AB  - Intra-canal fracture of rotary NiTi instruments occurs due to torsional stress, cyclic fatigue, or a combination of these two factors. Broken instruments are a serious obstacle to shaping, cleaning, and filling of the root canal and can adversely affect the outcome of endodontic therapy. The aim of this study was to examine the magnetic properties and ultrastructural changes of new, used, and fractured NiTi instruments using opto-magnetic imaging spectroscopy (OMIS). The study included three sets of different types of rotary instruments: MTwo (VDW, Munich, Germany), Pro Taper Universal (Dentsply Maillefer, Ballaigues, Switzerland), and BioRace (FKG DENTAIRE Swiss Dental Products, Le Cret-du-Locle Switzerland). Root canal shaping was performed on root canals with different curvatures, and after intra-canal fracture, in-struments of the same type (new, used, and fractured) were analyzed using OMIS at the Faculty of Mechanical Engineering, University of Belgrade. The obtained results showed a coincidence of peak localization for the used instruments that did not suffer a fracture, as well as for new, unused instruments of all examined groups. Additionally, there was a coincidence of peak intensities for new and fractured instruments in all groups. The specific treatment of electropolishing of the active surface of BioRace instruments caused a completely different electromagnetic response compared to conventional NiTi sets of tested instruments. New, unused BioRace instruments had the most pronounced pos-itive (5.6078 n.a.u. x1000) and negative (-8.5218 n.a.u. x1000) intensity values. The analysis of NiTi instruments using opto-magnetic imaging spectroscopy indicated changes in the magnetic properties after their instrumentation.

AB  - Introduction: Preparation of glide path is an important precondition for the safe use of rotary NiTi instruments during endodontic treatment. Aim: The aim of this study was to examine the duration of glide path preparation as well as all the changes in canal morphology and canal diameter after the use of hand K-files and NiTi rotary PathFiles. Material and methods: This research was performed on a total of twenty Endo Training Blocks (Dentsply, Maillefer, Switzerland). The glide path was prepared using hand stainless steel K-files ISO #10-15-20 (Dentsply, Sirona, USA) (n = 10) and NiTi rotary PathFiles ISO #13, #16 and #19 (Dentsply, Sirona, Switzerland) (n = 10). The time required to establish the glide path was measured with an iPhone stopwatch (Apple Inc. Cupertino, California). The images of the apical segment of canals before and after glide path preparation were taken under the stereomicroscope (Boeco BSZ-405, Germany), and then images were analyzed and processed with Scopeimage 9.0 (Teleskop, Austria). Statistical analysis was performed with the Mann-Whitney test at the level of significance 5% (a = 0.05). Results: A statistically significant difference was observed in terms of the time required for glide path preparation. The mean total time for glide path preparation was significantly longer with K-files (382 ± 62 s) than with PathFile (200 ± 11 s) (p < 0.05). A statistically significant difference in terms of changing the morphology of the apical part of the canal (p > 0.05) was not observed. The difference in the diameter of the root canal was at the limit of statistical significance (p ≈ 0.05). Conclusion: Instrumentation with NiTi rotary PathFiles reduces the time required for glide path preparation. Preparing endodontic space for rotary instrumentation with hand K-Files and rotary PathFiles leads to similar changes in the morphology of the apical segment. A slightly larger diameter of the root canal was measured after preparation with the hand K-files.
AB  - Uvod: Uspostavljanje instrumentacione putanje je važan preduslov za bezbednu primenu mašinskih NiTi instrumentata tokom oblikovanja kanalskih sistema. Cilj: Cilj ovog rada je bio da se uporedi vreme potrebno za formiranje instrumentacione putanje, kao i promene u morfologiji apikalnog segmenta i prečniku apikalnog otvora kanala posle primene ručnih K-turpija i mašinskih PathFile instrumenata. Materijal i metode: Istraživanje je realizovano na 20 "endo trening" modela (Dentsply Maillefer, Switzerland). Instrumentaciona putanja je uspostavljena primenom ručnih K-turpija od nerđajućeg čelika (#10-15-20) (Dentsply, Sirona, Switzerland) (n = 10), odnosno mašinskih PathFile NiTi instrumenata (Dentsply, Sirona, Switzerland) (n = 10). Vreme potrebno za uspostavljanje instrumentacione putanje mereno je iPhone stopwatch (Apple Inc. Cupertino, California). Slike apikalnog segmenta kanala, pre i posle formiranja instrumentacione putanje, snimane su stereomikroskopom (Boeco BSZ-405, Germany), a zatim obrađene i analizirane u softverskom programu Scopeimage 9.0. Dobijeni podaci statistički su obrađeni Man-Vitnijevim (Mann-Whitney) testom (a = 0,05). Rezultati: Uočena je statistički značajna razlika u pogledu vremena potrebnog za uspostavljanje instrumentacione putanje između ručnih K-turpija (6 min. 22 s) i mašinskih PathFile instrumenata (3 min. 20 s) (p < 0,05). U pogledu morfologije apikalnog segmenta nisu uočene značajne razlike (p > 0,05). Razlike u prečniku apikalnog otvora bile su na granici statističke značajnosti (p ≈ 0,05). Zaključak: Primena mašinskih PathFile instrumenata rezultirala je bržim formiranjem instrumentacione putanje u poređenju sa ručnim K-turpijama. Obe ispitivane grupe instrumenata dovele su do sličnih promena u morfologiji apikalnog segmenta kanala. Nešto veći prečnik apikalnog otvora kanala izmeren je posle primene ručnih K-turpija.

AB  - Background/Aim. There is no standard protocol for cleaning and disinfection of used endodontic instruments before their sterilization and reuse. The aim of this study was to determine the efficiency of the different methods of removing biological debris from different types of used hand stainless steel endodontic instruments. Methods. A total of 120 hand stainless steel endodontic instruments: KerrTM reamers, KerrTM files, and HedströmTM files, each forty ISO 25, used for root canal treatment on extracted teeth, were analyzed. The used instruments were divided into four groups based on different decontamination protocols. The evaluation of the efficiency of the cleaning methods was based on the evaluation of the amount of stained organic residues on the instruments (Van Gieson staining). Samples were analyzed by stereomicroscopy (x40). Statistical analysis was performed using the Mann-Whitney U test for the KerrTM reamers and HedströmTM files, while the One-Way ANOVA/Bonferroni test was used for the KerrTM files, at a significance level of 5% (a = 0.05). Results. Residual biological debris was observed on 93.3% of all the samples taken. The thermal disinfectant cleaning method showed the lowest contamination values for all types of instruments. The method of mechanical cleaning showed that the mean value of maximum biologic contamination (MBC) was 58.5% for the KerrTM reamers and 56.2% for KerrTM files, while for HedströmTM files, the highest MBC (50.2%) was shown by the ultrasonic method of cleaning. Conclusion. The use of a thermal disinfectant was the most efficient cleaning method for all three types of hand endodontic instruments.
AB  - Uvod/Cilj. Ne postoji standard za čišćenje i dezinfekciju upotrebljenih endodontskih instrumenata pre njihove sterilizacije i ponovnog korišćenja. Cilj rada bio je da se ustanovi efikasnost različitih metoda uklanjanja ostataka biološkog materijala sa radnih površina upotrebljenih ručnih endodontskih instrumenata od nerđajućeg čelika. Metode. Analizirano je ukupno 120 ručnih endodontskih instrumenata od nerđajućeg čelika: po četrdeset KerrTM proširivača, KerrTM turpija i HedströmTM turpija ISO 25, upotrebljenih za obradu kanala korena na ekstrahovanim zubima. Na osnovu protokola koji je korišćen za dekontaminaciju instrumenata, upotrebljeni instrumenti su podeljeni u četiri grupe. Procena efikasnosti korišćenih metoda čišćenja zasnovana je na proceni količine prebojenih organskih ostataka na instrumentima (bojenje po Van Gieson-u). Uzorci su analizirani stereomikroskopijom (x40). Statistička analiza dobijenih rezultata izvršena je MannWhitney U testom za KerrTM proširivače i HedströmTM turpije dok je za KerrTM turpije korišćen One-Way ANOVA/Bonferoni test, na nivou pouzdanosti od 5% (a = 0,05). Rezultati. Prisustvo rezidualnih ostataka biološkog materijala uočeno je na 93,3% svih analiziranih instrumenata. Metoda čišćenja toplotnim dezinfikatorom pokazala je najniže vrednosti kontaminacije za sve tipove instrumenata. Metoda mehaničkog čišćenja pokazala je da je srednja vrednost parametra maksimum biološke kontaminacije (MBK) bila 58,5% za KerrTM proširivače i 56,2% za KerrTM turpije, dok je za HedströmTM turpije najviša vrednost MBK (50,2%) bila posle ultrazvučne metode čišćenja instrumenata. Zaključak. Primena toplotnog dezinfikatora je najefikasnija metoda čišćenja za sva tri tipa ručnih endodontskih instrumenata.

AB  - Glide path is a procedure that precedes mechanical instrumentation of the root canals. It is defined as a procedure used to expand or create a smooth tunnel from the coronal part of the root canal to its physiological terminus. It is performed using small-size hand files or specially designed mechanical NiTi instruments. An adequately created glide path extends the life of rotary NiTi instruments, enables better mechanical and chemical debridement and easier preservation of original morphology of endodontic space during further mechanical instrumentation. Frequent use of mechanical instrumentation in daily practice requires better understanding of the glide path, its significance, and instruments and techniques used for its creation.

AB  - Introduction/Objective of this study is to use scanning electron microscopy (SEM) analysis to examine surfaces of new and same sets of Ni-Ti instruments after canal preparations, to check their suspectability to corrosion. Methods In this study, we used five different endodontic Ni-Ti instruments: K3, Mtwo, ProTaper Universal, HyFlex and BioRaCe. Instruments were analyzed before and after preparation of canals of different curvature, using SEM (150-2000 ×). Results Corrosion of the working part was observed in 5.5% of new Ni-Ti instruments of the K3 system (apical and middle segment), in 5.5% of Mtwo instruments (apical third), and in 11.1% of ProTaper Universal systems (apical and middle third). Corrosion was not observed on the new instruments of the HyFlex and BioRaCe kits. After instrumentation, disinfection, and sterilization, corrosion was observed in all sets of K3 and ProTaper Universal systems and in all HyFlex instruments of the first group. Corrosion was observed in the HyFlex system in the second group in 16.7% of instruments (apical and middle third) and in the third 83.3% in the apical and 66.7% in the middle segment. In the Mtwo set, corrosion was observed in 16.7% of instruments in the first (apical and middle third), in the second group in 33.3% of instruments in the apical part and 50% in the middle third, while in the third group, corrosion was observed in 16.7% of instruments in the middle third of instruments. Conclusion Rotary Ni-Ti instruments K3 and ProTaper Universal are susceptible to corrosion in a very high percentage. Ni-Ti systems with post-heat treatment of the working part (HyFlex) are somewhat more resistant to corrosion, while in Ni-Ti systems with electropolished surface (BioRaCe), corrosion is not observed.
AB  - Uvod/Cilj Cilj istraživanja je bio da se primenom skenirajuće elektronske mikroskopije (SEM) analiziraju površine nekorišćenih i istih setova nikl-titanijmskih (Ni-Ti) rotirajućih instrumenata nakon preparacije kanala, odnosno da se proveri njihova podložnost za pojavu korozije. Metod U istraživanje je uključeno pet različitih setova mašinskih endodontskih Ni-Ti instrumenata: K3, Mtwo, ProTaper Universal, HyFlex i BioRaCe. Instrumenti su analizirani pre upotrebe i nakon preparacije kanala različite povijenosti, pomoću SEM-a (150-2000 ×). Svaki set instrumenata je korišćen za obradu 10 kanala u tri eksperimentalne grupe (pravi, blago i izrazito povijeni kanali). Rezultati Korozija radnog dela uočena je kod 5,5% novih Ni-Ti instrumenata sistema K3 (apikalni i srednji segment), kod 5,5% Mtwo instrumenta (apikalna trećina) i kod 11,1% sistema ProTaper Universal (apikalna i srednja trećina). Korozija nije uočena na novim instrumentima HyFlex i BioRaCe setova. Nakon instrumentacije, dezinfekcije i sterilizacije korozija je primećena kod svih setova sistema K3 i ProTaper Universal i kod svih HyFlex instrumenata prve grupe. Korozija je uočena kod HyFlex sistema u drugoj grupi kod 16,7% instrumenata (apikalna i srednja trećina), a u trećoj grupi kod 83,3% instrumenata u apikalnom i 66,7% u srednjem segmentu. Kod Mtwo seta korozija je uočena kod 16,7% instrumenata u prvoj grupi (apikalna i srednja trećina), u drugoj grupi kod 33,3% instrumenata u apikalnom delu i 50% u srednjoj trećini, dok je u trećoj grupi korozija primećena kod 16,7% instrumenata u srednjoj trećini instrumenata. Zaključak Rotirajući Ni-Ti instrumenti K3 i ProTaper Universal podložni su koroziji u veoma visokom procentu. Ni-Ti sistemi sa naknadnom termičkom obradom radnog dela (HyFlex) nešto su otporniji na koroziju, dok kod Ni-Ti sistema sa elektropoliranom površinom (BioRaCe) korizija nije uočena.

AB  - Introduction. Deformations and fractures of Ni-Ti instruments during chemomechanical instrumentation of root canals occur due to the action of cyclic and torsional forces. The aim of this research was to analyze the surfaces of the working parts of Mtwo instruments after preparation of root canals with different curvatures using SEM and determine possible changes and deformations after instrumentation. Materials and methods. The study included 3 sets of Mtwo (VDW, Munich, Germany) instruments. Each set was used to instrument 10 canals in three experimental groups (straight, slightly curved, and highly curved canals). Instrumentation was carried out using crown-down technique with the following irrigation solutions, 2% NaOCl (CHLORAXID 2%, Cerkamed, Polska) and Distilled water (Iva, Serbia) in the amount of 5 cm3. The apical and middle third of the instruments were scanned in two directions using SEM at different magnifications (150-2000X). The SEM images were analyzed using qualitative analysis for the presence of different irregularities according to Eggert et al. Statistical analysis of obtained data was performed using Fisher test at a confidence level of 5% (α = 0.05). Results. Most defects (37.3%) were observed in instruments used in highly curved canals, followed by the instruments of the second group (35.6%), and the least defects were (27.1%) observed in the group with straight canals. Higher prevalence of defects was observed in the apical thirds of instruments (54.2%), especially in the experimental group of curved canals where the highest presence was observed (20.3%). The presence of production grooves was observed in all instruments, and the most common types of defects after instrumentation were the appearance of corrosion and changes in the cutting edges. In the group with extremely curved canals fractures were observed in two instruments (10/0.04 and 15/0.05). Conclusion. Root canal curvature significantly affects the occurrence of deformations and fractures of Ni-Ti rotating instruments. The most common types of defects were grooves, corrosion and changes in the blade edges. Mtwo instruments showed deformations in terms of thread changes, microfractures and two complete fractures.
AB  - Uvod Deformacije i fraktura Ni-Ti instrumenata tokom hemomehaničke obrade kanala nastaju usled dejstva cikličnih i torzionih sila. Cilj ovog istraživanja je bio da se primenom SEM-a analiziraju površine radnog dela MTwo instrumenata nakon preparacije kanala različite povijenosti i utvrdi eventualno postojanje promena i deformacija nakon instrumentacije. Materijali i metode U istraživanje su uključena tri seta MTwo (VDW, Munich, Germany) instrumenata. Svaki set je korišćen za obradu 10 kanala u tri eksperimentalne grupe (pravi, blago povijeni i izrazito povijeni kanali). Instrumentacija je realizovana kruničnoapeksnom tehnikom, a kao irigansi su primenjeni u količini od po 5 cm³, 2% rastvor NaOCl (CHLORAXID 2%, Cerkamed, Poljska) i destilovana voda (Iva, Srbija). SE snimci apikalne i srednje trećine instrumenata iz dva različita pravca, snimani pomoću SEM-a, na različitim uvećanjima (150-2000×) analizirani su kvalitativnom analizom prisustva različitih nepravilnosti po Edžeru i sar. Statistička analiza dobijenih podataka urađena je primenom Fišerovog testa na nivou pouzdanosti od 5% ( a = 0,05). Rezultati Najviše defekata (37,3%) uočeno je na instrumentima koji su upotrebljeni za obradu izrazito povijenih kanala, zatim na instrumentima druge grupe (35,6%), a najmanje defekata je bilo (27,1%) u grupi sa pravim kanalima. Veća zastupljenost defekata se uočava na apikalnoj trećini instrumenata (54,2%), posebno u trećoj eksperimentalnoj grupi, gde je uočeno najveće prisustvo - 20,3%. Uočeno je prisustvo proizvodnih žlebova na svim instrumentima, a najučestaliji tipovi defekta nakon instrumentacije su bili pojava korozije i promene sečivnih ivica. Uočene su frakture na dva instrumenta (10/0,04 i 15/0,05) u grupi sa izuzetno povijenim kanalima. Zaključak Na osnovu rezultata ove studije može se zaključiti da povijenost korenskog kanala znatno utiče na pojavu deformacija i prelom Ni-Ti rotirajućih instrumenata. Najučestaliji tipovi defekata su bili žlebovi, korozija i promene sečivnih ivica. MTwo instrumenti su pokazali deformacije u vidi promene navoja, mikrofraktura i dve kompletne frakture.

Mtwo instruments showed deformations in terms of thread changes, microfractures and two complete fractures., Uvod Deformacije i fraktura Ni-Ti instrumenata tokom hemomehaničke obrade kanala nastaju usled dejstva cikličnih i torzionih sila. Cilj ovog istraživanja je bio da se primenom SEM-a analiziraju površine radnog dela MTwo instrumenata nakon preparacije kanala različite povijenosti i utvrdi eventualno postojanje promena i deformacija nakon instrumentacije. Materijali i metode U istraživanje su uključena tri seta MTwo (VDW, Munich, Germany) instrumenata. Svaki set je korišćen za obradu 10 kanala u tri eksperimentalne grupe (pravi, blago povijeni i izrazito povijeni kanali). Instrumentacija je realizovana kruničnoapeksnom tehnikom, a kao irigansi su primenjeni u količini od po 5 cm³, 2% rastvor NaOCl (CHLORAXID 2%, Cerkamed, Poljska) i destilovana voda (Iva, Srbija). SE snimci apikalne i srednje trećine instrumenata iz dva različita pravca, snimani pomoću SEM-a, na različitim uvećanjima (150-2000×) analizirani su kvalitativnom analizom prisustva različitih nepravilnosti po Edžeru i sar. Statistička analiza dobijenih podataka urađena je primenom Fišerovog testa na nivou pouzdanosti od 5% ( a = 0,05). Rezultati Najviše defekata (37,3%) uočeno je na instrumentima koji su upotrebljeni za obradu izrazito povijenih kanala, zatim na instrumentima druge grupe (35,6%), a najmanje defekata je bilo (27,1%) u grupi sa pravim kanalima. Veća zastupljenost defekata se uočava na apikalnoj trećini instrumenata (54,2%), posebno u trećoj eksperimentalnoj grupi, gde je uočeno najveće prisustvo - 20,3%. Uočeno je prisustvo proizvodnih žlebova na svim instrumentima, a najučestaliji tipovi defekta nakon instrumentacije su bili pojava korozije i promene sečivnih ivica. Uočene su frakture na dva instrumenta (10/0,04 i 15/0,05) u grupi sa izuzetno povijenim kanalima. Zaključak Na osnovu rezultata ove studije može se zaključiti da povijenost korenskog kanala znatno utiče na pojavu deformacija i prelom Ni-Ti rotirajućih instrumenata. Najučestaliji tipovi defekata su bili žlebovi, korozija i promene sečivnih ivica. MTwo instrumenti su pokazali deformacije u vidi promene navoja, mikrofraktura i dve kompletne frakture.",

AB  - More certain therapeutic and significantly facilitated solution of everyday endodontic problems are provided by the introduction of NiTi rotary files in endodontic practice and their proper application. However, their widespread use has caused more and more frequent fractures and has become a significant frustrating factor that diminishes their numerous benefits. Torsional stress and cyclic fatigue are the main reasons for the occurrence of a fracture, and the frequency of NiTi file fractures is exactly proportional to the degree of bending of the canal, knowledge of the features of the file, ie. the skill and expertise of the therapist. The most dominant factor for the occurrence of fractures is the dentist who, in addition to manual dexterity, must have a good knowledge of the anatomy of various canal systems and file design in order to make the best choice for each individual case. Properly formed access cavity and knowledge of the working part of NiTi files enable maximum realization of endodontic skills, increased efficiency of intervention and reduced possibility of error during canal instrumentation. The special treatment of NiTi alloy and new solutions related to the design of the working part have significantly increased file flexibility and resistance to cyclic fatigue. Specific design (reduced number of threads, change of conicity, interruption of blade continuity), reduced engagement of file, ie. change of dynamics of movement in the canal (full rotation, reciprocal, eccentric, transaxial), as well as reduced number of processing files, have also significantly influenced the reduction of fracture risks. The aim of this paper was to analyze the most common reasons for the fracture of NiTi files and emphasize measures and factors that can increase their safe use and reduce complications during canal instrumentation.

Međutim, njihova široka primena uzrokovala je sve učestalije frakture i postala značajan frustrirajući faktor koji umanjuje njihove brojne benefite. Torziono naprezanje i ciklični zamor su glavni razlozi za nastanak frakture, a učestalost loma NiTi turpija je upravo srazmerna stepenu povijenosti kanala, poznavanju karakteristika instrumenta, odnosno veštini i stručnosti terapeuta. Najdominantniji faktor za nastanak fraktura je stomatolog, koji osim manuelne spretnosti mora dobro poznavati anatomiju različitih kanalskih sistema i dizajn turpije kako bi napravio najbolji izbor za svaki pojedinačni slučaj. Pravilno formiran pristupni kavitet i poznavanje radnog dela NiTi instrumenata omogućavaju maksimalnu realizaciju endodontske veštine, povećanu efikasnost intervencije i smanjenu mogućnost greške tokom obrade kanala. Poseban tretman NiTi legure i nova rešenja vezana za dizajn radnog dela značajno su povećali fleksibilnost turpije i otpornost na ciklični zamor.

Cilj ovog rada je bio da ukaže na najčešće razloge za pojavu fraktura NiTi turpija i apostrofira mere i faktore koji mogu povećati sigurnost instrumentacije i smanjiti moguće komplikacije tokom obrade kanala.

AB  - Introduction. Modern endodontic procedure implies the use of rotary Ni-Ti instruments during chemomechanical treatment of root canals. The aim of this study is to analyze the surfaces of new (unused) rotary endodontic instruments using the SEM-EDS method and determine how frequently manufacture defects or impurities appear on their working surfaces. Material and method. Five new different sets of rotary endodontic Ni-Ti instruments were included in this study: K3, Mtwo, ProTaper Universal, HyFlex and BioRaCe. The working part of endodontic instrument was analyzed using SEMEDS method (magnifications ×150 to ×2000), which determined the morphological characteristics of the instrument surface and chemical composition of the found impurities. Statistical analysis was performed using the Fisher’s test (p < 0.05). Results. The results of SEM-EDS analysis showed that there is no new instrument without defects on its surface. The most common defects were observed in K3 (27.43%) and ProTaper Universal group (27.21%) and the least were in BioRaCe instruments (7.67%). The most common type of defect in tested instruments was fretting. In addition, the presence of debris and metal strips was found on all instruments, while corrosion of the working part was observed only in K3, ProTaper Universal and Mtwo systems in a small percentage. Conclusion. Based on the results of this research, it can be concluded that manufacturing defects were noticed in all examined instruments. The most common defect is pitting. Impurities such as debris and metal strips have also been registered. No organic debris was observed on electropolished surface of BioRaCe instruments, but a small percentage of other types of defects were registered.

AB  - Introduction. The aim of this study was to analyze working surfaces of new hand endodontic instruments and to check possible existence of dirt or defects on working surface that resulted from manufacturing process using SEM. Material and methods. Three sets of new hand instruments: K-File (KF), (18 instruments) (Dentsply Maillefer, Switzerland) and Hedstorm Files (HF), (18 instruments) (SybronEndo Co, USA) were used. Instruments were analyzed by SEM method at 170× magnification while semi-quantitative EDS analysis was used to determine chemical composition of dirt particles. Fisher test (p < 0.05) was applied in statistical analysis. Results. Results showed that none of the instruments was defect-free. The most common defects were metal strips and fretting noticed at the surface of all tested instruments. Debris was present on all KF (100% in apical and middle third) and HF (56% in apical and 56% in middle third) instruments. Pitting was noticed in KF (33% in apical and 39% in middle third) and HF (11% in apical and 6% in middle third) instruments. Corrosion of working surface, metal flash and disruption of cutting edge were marked only in KF group. Conclusion. Manufacturing defects were noticed in all instruments and the most common type of irregularity were metal strips and fretting.

AB  - Introduction/Objective. The objective of this study is to use scanning electron microscopy (SEM) to analyze working surfaces of new manual and rotary endodontic instruments and to check possible existence of manufacture dirt particles or defects on the working surface. Methods. In this study, we used three sets of new manual instruments: K-File, KF (Dentsply Maillefer, Switzerland) and Hedstorm Files, HF (SybronEndo Co, USA) and three sets of mechanical Ni-Ti instruments – type K3 (SybronEndo Co, USA) and BioRaCe (FKG DENTAIRE Swiss Dental Products, Switzerland). The instruments were analyzed using SEM method at 170 × magnification while semi-quantitative energy dispersive x-ray analysis was used to determine chemical composition of dirt particles. Fisher test (p < 0.05) was applied in statistical analysis. Results. Results showed that none of the instruments were defect-free. The most common defect type was the presence of metal strips, which were noticed at the surface of all tested instruments. Debris was present on all manual and only one type of mechanical instruments, K3 (39% in the apical and 33% in the middle third). Fretting was noticed in all manual KF and all mechanical instruments of the K3 group. Pitting was common in all manual instruments, KF (33% in the apical and 39% in the middle third) and HF (11% in the apical and 6% in the middle third). Corrosion of the working surface, metal flash, and disruption of the cutting edge were marked only in the KF group. Conclusion. Manufacture defects were noticed in all instruments and the most common type of irregularity were metal strips. Electropolished surface of BioRaCe instruments showed no debris of organic origin.

AB  - Introduction/Objective Irrigation has an important role in root canal cleaning and its efficiency depends on the type of irrigants, the amount, the technique and the irrigation protocol. The aim of this work was to estimate the efficiency of cleaning of the canal walls by using scanning electron microscope analysis after the instrumentation by rotary NiTi instruments with the use of three different irrigation solutions and two final irrigation protocols. Methods Sixty extracted human incisors were divided into two groups after the rotary instrumentation with the iRace instruments. In both groups, the same amount (1.5 ml) of three solutions (2% sodium hypochlorite solution, 2% chlorhexidine solution, and 10% citric acid solution) and total final irrigation time (90 seconds) was the same. The final irrigation in the first group was accomplished using the technique of continuous irrigation and in the second group it was done using the intermittent protocol. The roots were cut longitudinally and analyzed by thirds (coronal, middle, and apical) on a scanning electron microscope (JSM 6460LV, JEOL Ltd., Tokyo, Japan) with 1,000× magnification. Results the most efficient cleaning of the root canal walls in both groups was seen after the use of citric acid with the intermittent protocol of the final irrigation (90.7% clean walls), while the least efficient was the final irrigation by chlorhexidine with continuous irrigation (80.3%). The most efficient cleaning of the canal walls in both groups was observed in the coronal third and the largest amount of the smear layer in the apical third. Conclusion the most efficient cleaning of the canal was achieved by the use of citric acid and the intermittent protocol of the final irrigation. In all tested solutions, the intermittent protocol of irrigation was more efficient than continuous irrigation.
AB  - Uvod/Cilj Irigacija ima važnu ulogu u čišćenju kanala korena, a njena efikasnost zavisi od vrste irigansa, količine, odnosno tehnike i protokola irigacije. Cilj ovog rada bio je da se analizom SEM proceni efikasnost čišćenja zidova kanala posle instrumentacije rotirajućim NiTi instrumentima uz primenu tri različita rastvora za irigaciju i dva protokola finalne irigacije. Metode Šezdeset ekstrahovanih humanih sekutića je posle mašinske instrumentacije iRaCe instrumentima podeljeno u dve grupe. U obe grupe su korišćena po tri rastvora - 2% rastvor natrijum-hipohlorita, 2% rastvor hlorheksidina i 10% rastvor limunske kiseline, u istoj količini (1,5 ml) i ukupnom vremenu finalne irigacije (90 sekundi). Finalna irigacija u prvoj grupi je realizovana tehnikom kontinuirane, a u drugoj tehnikom intermitentne irigacije. Korenovi su presečeni uzdužno i analizirani po trećinama (krunična, srednja i apikalna) na skenirajućem elektronskom mikroskopu (JSM 6460LV JEOL, Tokio, Japan) na uveličanju od 1000×. Rezultati Najefikasnije čišćenje zidova kanala korena u obe grupe uočeno je posle primene limunske kiseline uz intermitentni protokol finalne irigacije (90,7% čistih zidova), dok je najmanje efikasna bila finalna irigacija hlorheksidinom uz kontinuiranu irigaciju (80,3%). Najefikasnije čišćenje zidova kanala i u prvoj i u drugoj grupi uočeno je u kruničnoj trećini, a najviše razmaznog sloja u apikalnoj trećini. Zaključak Najefikasnije čišćenje kanala ostvareno je primenom limunske kiseline i intermitentnog protokola finalne irigacije. Kod svih testiranih rastvora intermitentni protokol irigacije je bio nešto efikasniji od protokola kontinuirane irigacije.

AB  - Introduction/Objective The application of nickel-titanium (NiTi) instruments in cleaning and shaping of the root canal system is a standard and a precondition for the success of endodontic treatment. The objective of this study was to use scanning electron microscopy (SEM) analysis in order to examine the efficiency of cleaning the apical third of the root canal system using two different NiTi systems with reciprocating movements. Methods The study included 20 single-rooted teeth (premolars) divided into two groups. In group 1, the canal preparation was realized with a single file UNICONE with reciprocating movements (MEDIN, Inc., Nové Město na Moravě, Czech Republic), and in group 2, with a RECIPROC BLUE instrument with reciprocating movements (VDW GmbH, Munich, Germany). The same quantities of 2% NaOCl solution and 17% EDTA solution were used as irrigation solutions. The samples prepared for SEM analysis of the smear layer in the apical third were evaluated on a scale of 1-5 and at a magnification of 1,000×. Results SEM analysis pointed to mostly clean canal walls in the apical segment in both tested groups. Slightly cleaner walls were observed after the application of the UNICONE file (78%) compared to the samples of the second group, where the instrumentation was realized by the RECIPROC BLUE file (76%), but without statistically significant differences. Conclusion Single-file reciprocating systems do not remove the smear layer completely, but provide efficient cleaning of the apical region of the canal.
AB  - Uvod/Cilj Primena instrumenata od legure nikl-titanijum (NiTi) u čišćenju i oblikovanju kanala je standard i preduslov za uspeh endodontskog tretmana. Cilj ovog rada je bio da se analizom skenirajućim elektronskim mikroskopom (SEM) proveri efikasnost čišćenja apikalne trećine kanala primenom dva različita NiTi sistema sa recipročnim pokretima. Metode U istraživanje je uključeno 20 jednokorenih zuba (pretkutnjaka) podeljenih u dve grupe. Preparacija kanala u prvoj grupi je realizovana jednom turpijom sa recipročnim pokretima UNICONE (MEDIN, Nove Mjesto u Moravskoj, Češka), a u drugoj instrumentom sa recipročnim pokretima RECIPROC BLUE (VDW Gmbh, Minhen, Nemačka). Kao rastvori za irigaciju korišćene su iste količine 2% rastvora NaOCl i 17% rastvor EDTA. Uzorci pripremljeni za analizu SEM razmaznog sloja u apikalnoj trećini su evoluirani prema skali 1-5 i na uveličanju od 1000×. Rezultati Analiza SEM je ukazala na uglavnom čiste zidove kanala u apeksnom segmentu u obe testirane grupe. Nešto čistiji zidovi uočeni su posle primene turpije UNICON (78%) u odnosu na uzorke druge grupe, gde je instrumentacija realizovana turpijom RECIPROC BLUE (76%), ali bez statistički značajnih razlika. Zaključak Recipročni sistemi sa jednom turpijom ne uklanjaju potpuno razmazni sloj, ali obezbeđuju efikasno čišćenje apikalne regije kanala.

Kao rastvori za irigaciju korišćene su iste količine 2% rastvora NaOCl i 17% rastvor EDTA. Uzorci pripremljeni za analizu SEM razmaznog sloja u apikalnoj trećini su evoluirani prema skali 1-5 i na uveličanju od 1000×. Rezultati Analiza SEM je ukazala na uglavnom čiste zidove kanala u apeksnom segmentu u obe testirane grupe. Nešto čistiji zidovi uočeni su posle primene turpije UNICON (78%) u odnosu na uzorke druge grupe, gde je instrumentacija realizovana turpijom RECIPROC BLUE (76%), ali bez statistički značajnih razlika. Zaključak Recipročni sistemi sa jednom turpijom ne uklanjaju potpuno razmazni sloj, ali obezbeđuju efikasno čišćenje apikalne regije kanala.",

AB  - Background/Aim: The aim of this study was to evaluate the efficacy of new rotary NiTi instrument XP-endo SHAPER (XPS) used with two irrigation protocols on the root canal cleaning in the apical area. Material and Methods: The research was conducted on 30 single-rooted teeth extracted for orthodontic reasons which were divided into the two groups. Instrumentation of the canals was conducted with XPS instrument and 2% solution of NaOCl was used as irrigant. Instrumentation in the first group was performed using a conventional continuous irrigation, in the second group, protocol of final irrigation was performed intermittently in 3 cycles. The SEM analysis of the apical third of the canal was performed on longitudinal root cross-section standardized photomicrography with a magnification of 2000X. Results: Results showed that a thicker smear layer was observed in the first group and with continuous irrigation protocol (2,10) in relation to the intermittent irrigation protocol in 3 cycles (1,96), but without significant differences. The walls of the root canal in the apical third of the samples of the second group were slightly cleaner (73.3%) in comparison with the teeth of the first group (64, 7%), but also without significant differences. Conclusions: The use of XPS and 2% solution of NaOCl in the root canal enables efficient cleaning of the apical third of tooth. The final irrigation protocol in three cycles improves the efficiency of the smear layer removal in the apical segment of the canal.

AB  - Introduction Efficient cleaning and canal design present a basic precondition for successful endodontic treatment. The aim of this study was to evaluate, using SEM analysis, the efficacy of cleaning the apical third of the canal with one instrument in both reciprocating motion and full rotation systems. Materials and methods Thirty (30) single-rooted teeth (upper incisors), extracted due to periodontal problems, were used and selected in 2 groups. In the group 1, instrumentation was done with a single instrument UNICONE with reciprocal movements (MEDIN, Czech Republic), while in the group 2, a single instrument XPS endo SHAPER (XPS) (FKG, Dentaire, Swiss) with full rotation was used. 2% solution of NaOCl and 17% EDTA solution were used as irrigation agents in both groups. SEM analysis of the smear layer in the apical third was done at standard magnification of 1000x and presented on a scale of 1-5. Results showed mostly clean canal walls and no smear layer in the apical region in both tested groups. Canal walls were somewhat cleaner after using UNICONE with reciprocal movements (80%) compared to the canals instrumented with XPS ENDO SHAPER (76%), but this difference was not statistically significant. Conclusion Single-file NiTi systems did not remove smear layer completely, but provided efficient cleaning in the api-cal part of the canal. UNICONE file with reciprocal movements was somewhat more efficient in removing the smear layer compared to the full rotation XPS ENDO SHAPER file.

AB  - Introduction the main objective of endodontic treatment is to eliminate infection from root canal and prevent re-infection by three-dimensional hermetic obturation of the canal system. Endodontic failure can occur due to inability of complete control and elimination of infection from the root canal. The aim of this study is to investigate, by PCR technique, microbiological status of previously endodontically unsuccessfully treated teeth immediately after the removal of obturation material. Material and Methods the analysis included 30 teeth indicated for endodontic retreatment. After removing previous root canal filling material, the bacteriological sample was taken by sterile instrument (# 15) and paper points. Standard PCR technique was used to analyze the incidence of E.faecalis, P.micros, P.intermedia, P. endodontalis and a.actinomycetemcomitans. Results Positive bacteriological findings were registered in 80% of cases, while bacteria were not identified in 20% of all samples (all taken from the root canals without significant changes in periapical tissue). From 24 canals with identified bacteria, 17 had affected apical periodontium. The most dominant microbe in root canals with positive bacteriological finding was E.faecalis (83.3% of the canals) and P.intermedia (75%). In case of teeth with chronic periapical changes, the most common was E. faecalis (94%) and P.intermedia (82.3%). Conclusion the presence of periapical lesions significantly affects microbiological status of endodontically treated teeth. The presence of bacteria was confirmed in most teeth with periapical lesions, while the most frequently identified bacteria were E. faecalis, P.intermedia and P.micros.
AB  - Uvod Osnovni zadatak endodontskog tretmana je da eliminiše infekciju iz kanala korena I spreči reinfekciju trodimenzionalnom hermetičkom opturacijom kanalskog sistema. Usled nemogućnosti potpune kontrole I eliminacije infekcije iz kanala korena može doći do pojave endodontskog neuspeha. Cilj ovog rada je bio da se neposredno posle uklanjanja materijala za opturaciju kod zuba sa neuspelim endodontskim lečenjem PCR tehnikom proveri mikrobiološki status endodontski lečenih zuba. Metode Mikrobiološka studija je obuhvatila 30 zuba (osam višekorenih I 22 jednokorena) indikovanih za ponovljeni endodontski tretman. Posle dezinfekcije radnog polja I dezopturacije koja je urađena isključivo mehaničkim putem, uzorak je uzet sterilnim kanalnim instrumentom tipa pulpekstirpatora (#15) ili Hoedstrem-turpije (#15) I uz pomoć papirnih poena kojima je sušen kanal. Ependorfice su čuvane na temperaturi od -20˚C do mikrobiološke analize. Putem klasičnog PCR analizirana je zastupljenost bakterija: Enterococcus faecalis, Peptostreptococcus micros, Prevotela intermedia, Porphyromonas endodontalis I Actinobacilus actinomicetemcomitans. Rezultati Pozitivan bakteriološki nalaz registrovan je u 80% slučajeva, dok bakterije nisu identifikovane u 20% uzoraka. Svi negativni uzorci su uzeti iz kanala korena zuba bez značajnih promena u apeksnom periodoncijumu, dok je 17 od 24 kanala sa identifikovanim bakterijama pripadalo zubima sa oštećenim apeksnim parodoncijumom. Najprisutniji mikroorganizam u kanalima sa pozitivnim bakteriološkim nalazom bio je E. faecalis, koji je identifikovan u 83,3% kanala, zatim P. inermedia sa 75% I P. micros sa zastupljenošću od 58,3%. Kod zuba sa hroničnim periapikalnim promenama najzastupljeniji je bio E. faecalis, koji je identifikovan u 94% kanala, zatim P. intermedia, koja je bila prisutna u 82,3% uzoraka. Mikroorganizmi E. faecalis I P. intermedia su registrovani kod svih pacijenata sa nekim od simptoma. Zaključak Prisustvo periapikalnih lezija značajno utiče na mikrobiološki status kanala korena endodontski lečenih zuba. Prisustvo bakterija u kanalima korena potvrđeno je u većini endodontski neuspešno lečenih zuba, a najčećše identifikovane bakterije bile su E. faecalis, zatim P. intermedia, P. micros I P. endodontalis.

AB  - Introduction Development of inflammatory lesions or their persistence after primary treatment is considered endodontic failure. The reason for failure can be complex anatomy of the canal system and numerous iatrogenic factors. The objective of this study was to analyze, clinically and radiographically, the causes of primary endodontic treatment failure and assess possibilities for retreatment of teeth with failed endodontic treatment. Method The study included 79 teeth (36 multirooted and 43 singlerooted tooth) indicated for repeated endodontic treatment. Based on the radiographic assessment of the status of periapical structures, teeth were divided into two groups. The first group included teeth without periapical lesions, i.e. the healthy periodontal tissues (PAI score of 1 and 2) in which retreatment was required for prosthodontic reason due to the poor quality of obturation (28 teeth), and the second group included teeth with visible signs of periapical tissue damage (PAI scores 3, 4 and 5) (51 teeth). In both groups, quality of obturation, coronal sealing and the presence or absence of clinical symptoms was analyzed. Results The most common radiographic finding of definitive obturation was short filling (65.8% of cases); “forgotten” canals (25.3%); non-homogeneous obturation with correct length (5.1%) and fractured instrument (3.8%). There was significant difference between healthy periodontal ligament and adequate restoration (P  lt  0.001). In 95% of patients with symptoms, changes in the periapical tissue were observed. Also, there was significant difference in the presence of symptoms after primary treatments, between the teeth with healthy apical periodontal tissue and teeth with periapical lesions (P = 0.019). Conclusion The outcome of the root canal treatment is significantly affected by the quality (density) of obturation and the presence and quality of coronal restoration. In patients with symptoms there were changes in the periapical tissue.

Razlog za neuspeh mogu biti kompleksna anatomija kanalnog sistema, ali i brojni jatrogeni faktori. Cilj ovog rada je bio da se kod zuba sa neuspelim endodontskim lečenjem klinički i radiografski analizira uzrok neuspeha primarnog endodontskog tretmana i procene mogućnosti za ponovni endodontski zahvat. Metod rada U ovo istraživanje je uključeno 79 zuba (36 višekorenih i 43 jednokorena zuba) indikovanih za ponovljeni endodontski tretman. Na osnovu radiografske ocene stanja periapikalnih struktura zubi su podeljeni u dve grupe: prvu grupu su činili zubi bez periapikalnih promena, tj. sa zdravim parodoncijumom (PAI skor 1 i 2) kod kojih je retretman bio neophodan iz protetskih razloga – zbog lošeg kvaliteta definitivne opturacije (28 zuba), a drugu zubi sa vidljivim znacima oštećenja apeksnog parodoncijuma (PAI skor 3, 4 i 5) (51 zub). U obe grupe analiziran je kvalitet opturacije, kvalitet kruničnog zaptivanja i prisustvo ili odsustvo kliničkih simptoma. Rezultati Najčešći radiografski nalazi kvaliteta definitivne opturacije kanala bili su: kratko punjenje (65,8% slučajeva), “zaboravljeni” kanali (25,3%), klinički nehomogeno punjenje uz korektnu dužinu definitivnog punjenja (5,1%) i frakturiran instrument (3,8%). Nađe- na je statistički visoko značajna razlika između adekvatne restauracije i zdravog parodoncijuma, odnosno pojave mikrocurenja zbog neadekvatne restauracije i periapikalnih promena (p  lt  0,001). Kod 95% pacijenata sa simptomima uočene su promene u apeksnom parodoncijumu. Takođe, nađena je statistički značajna razlika u prisustvu simptoma nakon primarne endodontske terapije između zuba sa zdravim parodoncijumom i zuba sa periapikalnim lezijama (p = 0,019) Zaključak Na ishod endodontskog lečenja značajno utiču kvalitet (hermetičnost) opturacije kanala korena, odnosno prisusutvo i kvalitet koronarne restauracije. Kod pacijenata sa simptomima uglavnom su postojale i promene u apeksnom parodoncijumu nakon endodontskog lečenja.

AB  - Introduction The aim of this study was to evaluate the efficacy of new rotary NiTi instrument XP endo SHAPER (XPS) used with conventional irrigation protocol on the root canal cleaning in the apical area. Material and methods The research was conducted in vitro on 40 extracted single-rooted teeth divided into the four groups. Instrumentation in the first group was performed using iRa Ce NiTi rotary instruments, in the second group the same instruments were used plus XP endo FINISHER (XPF) for smear layer removal. In the third group, canal instrumentation was done using new instrument XPS, and in the fourth XPS instruments plus XPF was used. During the instrumentation 2% NaOCl solution was used for rinsing canals. The SEM analysis of the cleaning quality in the apical third of the canal was performed on longitudinal root cross-sections and standardized microphotography with a 2000x magnification. Results The thickest smear layer in the apical third was recorded in the first group (iRa Ce) NiTi instruments (2.12), and somewhat less in the group with the new XPS instrument (1.95). An identical and somewhat smaller amount of smear layer was registered in the second and fourth groups where XPF was used with the final irrigant (1.64) (p lt 0.001). Conclusion The application of only one instrument (XPS) in the canal enabled efficient cleaning of a very complex apical third. Cleaning was more efficient when XPF was used with final irrigant after the canal instrumentation.

AB  - Introduction Endodontic retreatment is a complex intervention that requires detailed analysis of possible reasons for failure, and flawless practical execution of the procedure. Objective The aim of the study was to assess the outcome of endodontic retreatment based on clinical and radiographic criteria after a two-year observation period. Methods Clinical study included 49 teeth indicated for endodontic retreatment based on periapical index (PAI). All teeth were divided into two groups. Group I comprised teeth without any periapical lesion (PAI score of 1 and 2) while Group II consisted of teeth with visible periapical radiolucency (PAI score of 3, 4, and 5). Endodontic retreatment was completed in two visits with inter-appointment medication of 2% chlorhexidine and calcium hydroxide for two weeks. Outcome of endodontic retreatment was evaluated 12-24 months after final obturation. Results Endodontic retreatment was successful in 93.3% in Group I after 24 months. In Group II, successful treatment and complete healing was found in 52.9% of teeth, whereas 14.7% of teeth showed only partial healing. However, clinical symptomatology was not present in any of the cases. Considering the absence of clinical signs and subjective symptoms, retreatment was successful in 67.6% of cases where chronic periapical inflammation was present. Conclusion Endodontic retreatment was successful in high percentage in teeth with and without periapical lesions.
AB  - Uvod Endodontski retretman je kompleksna intervencija koja zahteva detaljnu analizu indikacija, odnosno perfektnu praktičnu realizaciju ovakvog zahvata. Cilj rada Cilj ovog rada je bio da se na osnovu kliničkih i radiografskih kriterijuma proceni ishod ponovljene endodontske terapije nakon perioda od dve godine kod pacijenata sa različitim endodontskim indikacijama. Metode rada Klinička studija je obuhvatila 49 zuba indikovanih za ponovljeni endodontski tretman, koji su na osnovu PAI (periapikalni indeks) skora podeljeni u dve grupe. U prvu grupu su svrstani zubi bez periapikalnih promena (PAI skor 1 i 2), dok su drugu grupu činili zubi sa vidljivim znacima oštećenja apeksnog parodoncijuma (PAI skor 3, 4 i 5). Ponovljeno endodontsko lečenje podrazumevalo je medikaciju 2% rastvorom hlor-heksidina i suspenzijom kalcijum-hidroksidom u trajanju od dve nedelje u obe grupe zuba. Ishod preduzete terapije procenjivan je na kliničkim i radiografskim kontrolama 12-24 meseca nakon definitivne opturacije. Rezultati Ponovljena endodontska terapija u grupi zuba sa zdravim parodontalnim tkivima nakon 24 meseca bila je upešna u 93,3% slučajeva.

abstract = "Introduction Endodontic retreatment is a complex intervention that requires detailed analysis of possible reasons for failure, and flawless practical execution of the procedure. Objective The aim of the study was to assess the outcome of endodontic retreatment based on clinical and radiographic criteria after a two-year observation period. Methods Clinical study included 49 teeth indicated for endodontic retreatment based on periapical index (PAI). All teeth were divided into two groups. Group I comprised teeth without any periapical lesion (PAI score of 1 and 2) while Group II consisted of teeth with visible periapical radiolucency (PAI score of 3, 4, and 5). Endodontic retreatment was completed in two visits with inter-appointment medication of 2% chlorhexidine and calcium hydroxide for two weeks. Outcome of endodontic retreatment was evaluated 12-24 months after final obturation. Results Endodontic retreatment was successful in 93.3% in Group I after 24 months. In Group II, successful treatment and complete healing was found in 52.9% of teeth, whereas 14.7% of teeth showed only partial healing. However, clinical symptomatology was not present in any of the cases. Considering the absence of clinical signs and subjective symptoms, retreatment was successful in 67.6% of cases where chronic periapical inflammation was present. Conclusion Endodontic retreatment was successful in high percentage in teeth with and without periapical lesions., Uvod Endodontski retretman je kompleksna intervencija koja zahteva detaljnu analizu indikacija, odnosno perfektnu praktičnu realizaciju ovakvog zahvata. Cilj rada Cilj ovog rada je bio da se na osnovu kliničkih i radiografskih kriterijuma proceni ishod ponovljene endodontske terapije nakon perioda od dve godine kod pacijenata sa različitim endodontskim indikacijama. Metode rada Klinička studija je obuhvatila 49 zuba indikovanih za ponovljeni endodontski tretman, koji su na osnovu PAI (periapikalni indeks) skora podeljeni u dve grupe. U prvu grupu su svrstani zubi bez periapikalnih promena (PAI skor 1 i 2), dok su drugu grupu činili zubi sa vidljivim znacima oštećenja apeksnog parodoncijuma (PAI skor 3, 4 i 5). Ponovljeno endodontsko lečenje podrazumevalo je medikaciju 2% rastvorom hlor-heksidina i suspenzijom kalcijum-hidroksidom u trajanju od dve nedelje u obe grupe zuba. Ishod preduzete terapije procenjivan je na kliničkim i radiografskim kontrolama 12-24 meseca nakon definitivne opturacije. Rezultati Ponovljena endodontska terapija u grupi zuba sa zdravim parodontalnim tkivima nakon 24 meseca bila je upešna u 93,3% slučajeva. U grupi sa periapikalnim promenama radiografski delimično poboljšanje zabeleženo je u 14,7%, a potpuno izlečenje u 52,9% slučajeva. S obzirom na odsustvo kliničkih znakova i subjektivnih simptoma, ponovljena terapija smatrana je uspešnom u oba slučaja, dakle u ukupno 67,6% zuba kod kojih su postojale hronične periapikalne lezije.

AB  - Dental fear represents a significant social concern. Therefore, an individual approach to each patient and timely recognition and elimination of dental stress are necessary in order to provide adequate and successful treatment. The aim of this paper was to present possible application of music therapy in dentistry and its role in reducing dental fear. Music has shown great prospective as an alternative therapy method in various fields of medicine. Music therapy is painless and noninvasive anxiolytic method that reduces dental anxiety as it provides relaxation and distraction. Music in dental office creates positive atmosphere among patients and their company as well as dental staff.

AB  - Introduction The aim of this study was to evaluate using SEM analysis the effectiveness of a new instrument XP-endo Finisher in cleaning root canal walls after instrumentation with BioRaCe NiTi rotary instruments. Material and Methods This in vitro study was conducted on 30 extracted single rooted teeth divided in two groups. Instrumentation of all canals was done using basic BioRaCe NiTi rotary instruments with copious irrigation of 2% NaOCl. In the first group, after complete instrumentation smear layer was removed using XP-endo Finisher, while the other group served as negative control. The roots were then after longitudinally cut and SEM analysis was performed. The presence of smear layer in the coronal, middle and apical third was assessed. The data were statistically analyzed using Mann-Whitney U-test (p lt 0.05). Results The results showed that average value of smear layer on the canal walls in the XP-endo Finisher group was significantly lower than in the control group (p lt 0.05). Conclusion XP-endo Finisher after canal instrumentation with NiTi rotary instruments effectively cleaned canal walls and removed smear layer.
AB  - Uvod Cilj ovog rada je bio da se SEM analizom proveri efikasnost novog instrumenta XP-endo Finisher na kvalitet čišćenja zidova kanala korena zuba nakon instrumentacije BioRaCe NiTi rotirajućim instrumentima. Materijal i metode rada Istraživanja su izvedena u uslovima in vitro na 30 ekstrahovanih jednokorenih zuba podeljenih u dve grupe. Instrumentacija svih kanala je realizovana osnovnim setom BioRaCe NiTi rotirajućih instrumenata uz irigaciju dvoprocentnim rastvorom NaOCl. U prvoj grupi je nakon instrumentacije za uklanjanje razmaznog sloja korišćen XP-endo Finisher, a druga grupa je služila kao kontrolna. Korenovi svih zuba su uzdužno podeljeni i SEM metodom je analiziran kvalitet čišćenja kanala korena, odnosno postojanje razmaznog sloja u kruničnoj, srednjoj i apeksnoj trećini. Podaci su statistički analizirani Man-Vitnijevim (Mann-Whitney) U-testom (p lt 0,05). Rezultati Dobijeni rezultati su pokazali da je ukupna srednja vrednost postojanja razmaznog sloja na zidovima kanala u grupi gde je korišćen XP-endo Finisher bila statistički značajno manja nego u kontrolnoj grupi uzoraka (p lt 0,05). Zaključak XP-endo Finisher posle obrade kanala NiTi rotirajućim instrumentima efikasno čisti kanal i uklanja razmazni sloj sa zidova kanala.

AB  - Dental anxiety might be the cause of serious health problems. Avoiding dental visits can lead to complications with functional, esthetic and sociological consequences. In order to have a simple and efficient dental procedure, it is very important to diagnose dental anxiety and to react adequately. The aim of this paper is using available literature to present most frequent causes, consequences as well as treatment options for dental anxiety. Treating dental anxiety and choosing the right treatment is not always easy, however, it is important for dental practitioners to be able to assess patient's behavior, possible causes of such behavior and select adequate therapy methods. Individual approach is very important as well as timely recognition and gradation of dental anxiety in order to apply adequate and successful dental treatment.

Za uspeh stomatološke intervencije i njeno lakše izvođenje veoma su važni pravilno dijagnostikovanje dentalne uznemirenosti i odgovarajuća reakcija stomatologa.
