AB  - Objective: This study aims to determine and compare the dental pulp and gingival blood flow in patients referred for oropharyngeal radiotherapy (RT) at three different time points: before the start, immediately after, and six months following the completion of RT. The aim is also to evaluate the dependence of the pulp and gingival blood flow on the radiation dose. Methodology: A prospective study included 10 patients referred for intensity-modulated RT (IMRT) in the oropharyngeal region, with at least one intact tooth surrounded by a healthy gingiva. The dose received by each selected tooth and adjacent gingiva was determined according to the map of treatment planning and computer systems. The blood flow measurements were performed using the laser Doppler flowmetry (LDF) method. Results: Comparing vascular flows at three different time points, the median blood flow in the dental pulp showed no statistically significant difference (p=0.325), contrary to gingiva (p=0.011). Immediately after RT completion, the gingival flow significantly increased compared to its starting point (p=0.012). The pulp flow correlated negatively with the radiation dose, whereas a strong correlation was noted 6 months following the RT completion. Conclusions: RT caused a significant acute gingival blood flow increase, followed by a long-term (over six months) tendency to return to the starting levels. The dental pulp blood flow is differently affected by higher radiation doses (over 50Gy) in comparison to lower doses (below 50Gy). During RT planning, considering the possibility of protecting the teeth localized near the Gross Tumor Volume as a sensitive organ is recommended.

AB  - Introduction: Open pores between endodontic sealer and root canal walls present potential niches for bacterial growth and migration pathways. The aim was to assess the internal and external porosity of calcium silicate-based sealers and to ascertain the long-term effect of storage in simulated body fluid on sealer porosity. Methods: Sixteen single-rooted teeth were filled with gutta-percha and 1 of 4 root canal sealers: BioRoot RCS, EndoSequence BC, MTA Fillapex, or AH Plus. Obturated roots, stored in Hank's balanced salt solution, were scanned after 7 days and after 6 months by using micro-computed tomography at an isotropic resolution of 9.9 mm. Total, open, and closed porosity were calculated in the coronal, middle, and apical thirds. Data were statistically analyzed by using general linear model and paired t test (alpha = 0.05). Results: Significantly higher percentage of open than closed porosity was found in all groups. Initially, significantly greater open and total porosity were found for MTA Fillapex than for AH Plus. After 6 months, the percentage of open and total porosity increased in BioRoot RCS and MTA Fillapex and decreased in AH Plus and EndoSequence BC. Both initially and after storage, coronal region of all sealers had significantly greater total porosity than middle and apical regions, which were comparable. Conclusions: None of the root fillings were void-free, with predominant open porosity persisting after long-term storage.

AB  - Introduction: Age-related changes of dental pulp tissue and atherosclerosis of carotid arteries as its feeding arteries could influence the functionality of pulpal circulation. The objective of our study was to evaluate the effect of aging (physiological process) and carotid bifurcation atherosclerosis (pathologic process) on the pulpal microcirculatory system using multifractal analysis of the laser Doppler flowmetry signal. Methods: Three groups of 10 subjects were enrolled in the study: the young group (healthy subjects, 20-25 years), the middle-aged group (healthy subjects, 50-60 years), and the clinical group (subjects with carotid bifurcation atherosclerosis, 50-60 years). Pulpal blood flow (PBF) signals recorded by laser Doppler flowmetry were assessed by multifractal analysis that estimates Holder exponents of the signal. PBF levels, the average mean values, and the range of Holder exponents were obtained. Results: PBF levels were significantly higher in the young group compared with the middle-aged and clinical groups, and the difference between the middle-aged and clinical groups was not statistically significant. The range of the Holder exponents was narrower in the middle-aged and clinical groups than in the young group and narrower in the clinical group than in the middle-aged group. The average mean value of Holder exponents was significantly higher in the young group than in the middle-aged and clinical groups, whereas there was no significant difference between the middle-aged and clinical groups. Conclusions: Our study investigating the multifractality of the PBF signal showed that the aging process and carotid atherosclerosis could affect the complex structure of PBF oscillations and contribute to a better understanding of pulpal hemodynamics.

AB  - Aim To investigate the effect of ageing on control mechanisms of pulpal microcirculation using wavelet analysis and to calculate linear and nonlinear parameters of blood flow oscillations, in a healthy general population. Methodology Pulpal blood flow (PBF) oscillations were recorded on right maxillary central incisors using laser Doppler Flowmeter (PeriFlux PF 5001, Perimed, Jarfalla, Sweden) on a group of 10 young participants (20-25 years) and a group of 10 older adults (60-70 years). In total, 20 recordings were obtained for at least 20 min (one recording on one tooth per subject). Using wavelet spectral analysis, the amplitude and power were calculated as a linear and Hurst exponent as a nonlinear parameter of PBF oscillations. Differences between the two groups were assessed with the independent Student t-test. Results Mean PBF levels were significantly lower (P = 0.024) in older adults than in young participants. Relative amplitudes and powers corresponding to the myogenic (P = 0.046, P  lt  0.001, respectively) and neurogenic activity (P = 0.04, P = 0.01, respectively) were significantly higher, whereas values corresponding to the endothelial function (P = 0.04, P = 0.01, respectively) were significantly lower in older adults than in young participants. Hurst exponents of the total spectrum, myogenic and endothelial component (P  lt  0.001, P = 0.02, P  lt  0.001, respectively) of PBF oscillations were significantly lower in older adults in comparison to young participants. Conclusions At the level of pulpal microcirculation, ageing was associated with altered blood flow levels, the contribution of different control mechanisms to blood flow oscillations as well as the interaction of vascular smooth muscle and endothelium. Described changes of pulpal haemodynamics contribute to a better understanding of physiological behaviour and decreased adaptability of aged dental pulp to pathological stimuli.

AB  - Introduction To obtain the ideal aesthetics, each restorative material must imitate natural tooth in color, surface texture and be stable over time. Damage or wear of the material causes poor optical properties of the restoration, so it is necessary to repolish, repair or replace it. The aim of this study was to test the gloss and surface changes of the composite materials with filler's particles of different size, before and after material artificial mechanical ageing. Material and Methods Four composite materials were tested, two microhybrid composites (Gradia Direct GC, Herculite XRV, Kerr) and two nanohybrid composites (Filtek Ultimate 3M; TetricEvoceram, Ivoclar). Composites' samples of 9 × 9 × 2 mm in size were polished in accordance to the standard protocol by Sof-Lex discs (2382 C, SM, F, SF) for 30 seconds. Gloss was measured after polishing and taking photos using optical microscope (400×). In the chewing simulator, ageing of the samples was conducted (100,000 cyclic kicks). After the samples' ageing, surface photos were taken and gloss measured. The obtained results were statistically processed (One-way ANOVA, t-test). Results The best gloss after polishing was shown by Filtek Ultimate (54.00 ± 14.06), the worst by Gradia Direct (47.33 ± 7.92). There was no statistically significant difference (p > 0.05) in surface gloss after polishing composite. The smallest defects on the surface of composites were detected in material Gradia Direct (21363.7 mm2 ) with the average value of the diameter 137 mm. Conclusion The tested nanohybrid and microhybrid composites showed comparable gloss value before and after artificial aging. Mechanical aging caused vivid changes regarding surface defects on all tested composite materials.
AB  - Uvod Da bi se dobila idealna estetika, svaki restaurativni materijal mora oponašati prirodni zub po boji i teksturi površine i mora biti stabilan u vremenu. Oštećenje ili habanje materijala uzrokuje loša optička svojstva ispuna, pa ga je neophodno prepolirati, reparirati ili zameniti. Cilj rada je bio da se ispitaju sjaj i površinske promene kompozita sa različitom veličinom čestica punilaca, pre i posle artificijalnog mehaničkog starenja. Materijal i metode Testirana su četiri kompozita, dva mikrohibridna (Gradia Direct GC; Herculite XRV, Kerr) i dva nanohibridna (Filtek Ultimate 3M; Tetric Evoceram, Ivoclar). Uzorci kompozita (9 × 9 × 2 mm) polirani su po standardnom protokolu diskovima Sof-Lex 30 sek. Posle poliranja izmeren je sjaj, a uzorci su posmatrani pod optičkim mikroskopom (×400). U simulatoru žvakanja uzorci su izloženi artificijalnom starenju sa 100.000 cikličnih udaraca. Posle mehaničkog starenja ponovo je izmeren sjaj, a površine su fotografisane i sačuvane u digitalnom formatu. Dobijeni rezultati su statistički obrađeni (One-way ANOVA, t-test). Rezultati Najveći sjaj posle poliranja pokazao je Filtek Ultimate (54,00 ± 14,06), a najmanji Gradia Direct (47,33 ± 7,92). Nije bilo statistički značajne razlike sjaja između testiranih materijala posle poliranja (p > 0,05). Najmanji defekti na površini kompozita uočeni su kod materijala Gradia Direct (21.364 mm), sa srednjom vrednošću prečnika 137 mm. Zaključak Ispitivani nanohibridni i mikrohibridni kompozitisu pokazali komparabilne vrednosti sjaja pre i posle artificijalnog starenja. Mehaničko starenje je izazvalo vidljive promene u vidu površinskih defekata na svim ispitivanim kompozitima.

Oštećenje ili habanje materijala uzrokuje loša optička svojstva ispuna, pa ga je neophodno prepolirati, reparirati ili zameniti. Cilj rada je bio da se ispitaju sjaj i površinske promene kompozita sa različitom veličinom čestica punilaca, pre i posle artificijalnog mehaničkog starenja. Materijal i metode Testirana su četiri kompozita, dva mikrohibridna (Gradia Direct GC; Herculite XRV, Kerr) i dva nanohibridna (Filtek Ultimate 3M; Tetric Evoceram, Ivoclar). Uzorci kompozita (9 × 9 × 2 mm) polirani su po standardnom protokolu diskovima Sof-Lex 30 sek. Posle poliranja izmeren je sjaj, a uzorci su posmatrani pod optičkim mikroskopom (×400). U simulatoru žvakanja uzorci su izloženi artificijalnom starenju sa 100.000 cikličnih udaraca. Posle mehaničkog starenja ponovo je izmeren sjaj, a površine su fotografisane i sačuvane u digitalnom formatu. Dobijeni rezultati su statistički obrađeni (One-way ANOVA, t-test). Rezultati Najveći sjaj posle poliranja pokazao je Filtek Ultimate (54,00 ± 14,06), a najmanji Gradia Direct (47,33 ± 7,92). Nije bilo statistički značajne razlike sjaja između testiranih materijala posle poliranja (p > 0,05). Najmanji defekti na površini kompozita uočeni su kod materijala Gradia Direct (21.364 mm), sa srednjom vrednošću prečnika 137 mm. Zaključak Ispitivani nanohibridni i mikrohibridni kompozitisu pokazali komparabilne vrednosti sjaja pre i posle artificijalnog starenja. Mehaničko starenje je izazvalo vidljive promene u vidu površinskih defekata na svim ispitivanim kompozitima.",

AB  - AimTo investigate melatonin (MEL) levels in human dental pulp tissue (hDP) in type 2 diabetic (T2D) participants and the underlying molecular mechanisms of its effects in human dental pulp cells (hDPCs) under hyperglycaemia. MethodologyThe study included 16 healthy and 16 T2D participants who underwent vital pulp extirpation for hDP and four healthy participants undergoing third molar extraction for hDPCs analyses. MTT and NRU were used as tests for cytotoxicity. The pulp tissue levels of MEL, inducible NO synthase (iNOS) and superoxide dismutase (SOD) activity, as well as iNOS, histone acetyltransferase p300 (p300) and SOD activity levels in hDPCs incubated with MEL (0.1 and 1.0mmolL(-1)) under normoglycaemia and hyperglycaemia were measured by enzyme-linked immunosorbent assay. Comparisons between the two groups were made by unpaired t-tests or Mann-Whitney test whilst the chi-square test was used for dichotomous variables. To compare more groups, the Kruskal-Wallis test with Dunn's multiple comparison was used, whilst Spearman correlation was used to assess association between two variables. ResultsMelatonin was decreased (124.3021.6 vs. 240.0 +/- 19.1 pgmL(-1), P lt 0.01), whilst iNOS levels increased (0.92 +/- 0.08 vs. 0.32 +/- 0.09ngmL(-1), P lt 0.01) in hDP from T2D compared to nondiabetic participants. In hDPCs, MEL (0.1 and 1.0mmolL(-1)) had no cytotoxicity. Incubation with 1.0mmolL(-1) of MEL (24h) decreased hyperglycaemia-induced increases of iNOS (0.34 +/- 0.01ngmL(-1) vs. 0.40 +/- 0.01ngmL(-1), P lt 0.01) and p300 (11.59 +/- 0.58ngmL(-1) vs. 16.12 +/- 0.39ngmL(-1), P lt 0.01), and also, increased SOD activity (87.11 +/- 3.10% vs. 68.56 +/- 3.77%, P lt 0.01) to the levels comparable to the normoglycaemic; iNOS and p300 protein expression levels showed strong positive correlation under hyperglycaemia (Spearman r=0.8242, P lt 0.001). ConclusionType 2 diabetic participants had decreased MEL in hDP. At pharmacological concentrations, MEL is not cytotoxic for hDPCs and normalizes iNOS and SOD activity levels in hyperglyceamic hDPCs suggesting its antioxidant and protective effects in human dental pulp tissue under hyperglycaemia.

AB  - Objectives: The aim of this study was to test long-term microtensile bond strength (mu TBS) of 2 universal adhesives applied to dentin following "total-etch" (TE) or "self-etch" (SE) protocols and aged by direct or indirect water exposure using simulated pulpal pressure. Materials and methods: Single Bond Universal (SBU, 3M ESPE) or Ipera Bond (IP, Itena) were applied to mid-coronal dentin ("flat dentin") or Class I cavity ("cavity dentin") following TE or SE protocols in 112 extracted human third molars. Sixteen groups (n=7 per group) were prepared, 8 groups for mu TBS measurements after 24 hours, and further 8 groups for measurements after 6 months storage. "Cavity dentin" groups were subjected to simulated hydrostatic pulpal pressure of 15 cm H2O using a custom-made device before cutting 1 x 1 mm sticks while "flat dentin" groups were cut into sticks and directly exposed to deionized water. Results: Generally, the TE protocol resulted in highest mu TBS values on flat dentin initially for both adhesives (general linear model, P lt .05). Long-term storage resulted in significantly lower mu TBS values for the TE protocol (P lt .05) while the SE protocol showed comparable values after 6 months (P>.05). "Cavity dentin" with simulated pulpal pressure resulted in lower mu TBS than "flat dentin" (P lt .05). For both adhesives, mu TBS was in the range of 19-42 MPa initially and 16-36 MPa after 6 months storage. Conclusions: mu TBS to dentin of universal adhesives is more stable in the long term following the SE than TE protocol. Simulated pulpal pressure and cavity-type sample preparation may be recommended for mu TBS testing as a more clinically relevant strategy.

AB  - Introduction Knowledge of biological and cultural heritage represents a significant basis for the advance of human civilization. The aim of this study was to determine and define dental health status of pre-historic people of the Vinca culture. Material and method Study included twenty skeleton remnants of different gender and age from anthropological series of Gomolava. Skeletons originated from one necropolis and two individual graves dating from mid and early Neolithic periods of the Vinca culture. Based on radiocarbon analysis absolute skeletal age was determined to date within the periods from 5848±38 to 5739±35 BC. Preservation of skeletons varied from completely preserved skulls and jaws to fragmented parts of jaws. Data analysis was performed with methodology used in the research of human population teeth and jaws from the Lepenski Vir culture. Results Results showed high level of teeth abrasion (98,1%), medium level of dental calculus deposits (44,9%), low level of tooth decay, significant number of retained roots, as well as the occurrence of periapical lesions and periodontal disease within the neolith population of Gomolava site. Conclusion Taking into account absolute age of examined skeletons, collected data are very significant, from the perspective of its wide content. From a pathological perspective, teeth abrasion stands out as a dominant feature, while tooth decay fits within standard values for human population of the neolith period.

AB  - Introduction Vascular network of dental pulp is supplied through common and external carotid artery and terminal dental branches that supply each pulp tissue. Age related changes of pulp tissue influence pulpal vascularization as well. The aim of this study was to compare and correlate pulpal and common and external carotid artery blood flow in young and middle age individuals of general population. Material and Methods Two groups of 10 participants were included in the study, young (20-25 years) and middle age (50-55 years) group. Pulpal blood flow (PBF) measurements on intact right and left upper central incisors were performed using laser Doppler flowmetry (LDF) method. Carotid arteries blood flow was assessed using carotid ultrasonography. Results PBF levels were significantly higher in young (3.11±0.67 and 3.46±1.11, right and left upper central incisors, respectively) compared to middle age (1.93±0.47 and 2.30±0.64, right and left upper central incisors, respectively) participants (independent sample t test; p lt 0.05). There was no correlation between common and external carotid artery blood flow and upper central incisors PBF in young as well as middle age participants, for right or left side. Conclusion Absence of correlation between carotid arteries blood flow and PBF suggests that reduced PBF in middle age participants was probably not due to reduced blood supply from carotid arteries but it was result of age related changes at the level of pulpal blood vessels.
AB  - Uvod Vaskularna mreža zubne pulpe dobija dotok krvi preko zajedničke i spoljašnje karotidne arterije i završnih zubnih grana koje snabdevaju svaku pojedinačnu pulpu. Mala fleksibilnost okruženja zubne pulpe pojačava promene vezane za starenje koje utiču na vaskularizaciju pulpe.

abstract = "Introduction Vascular network of dental pulp is supplied through common and external carotid artery and terminal dental branches that supply each pulp tissue. Age related changes of pulp tissue influence pulpal vascularization as well. The aim of this study was to compare and correlate pulpal and common and external carotid artery blood flow in young and middle age individuals of general population. Material and Methods Two groups of 10 participants were included in the study, young (20-25 years) and middle age (50-55 years) group. Pulpal blood flow (PBF) measurements on intact right and left upper central incisors were performed using laser Doppler flowmetry (LDF) method. Carotid arteries blood flow was assessed using carotid ultrasonography. Results PBF levels were significantly higher in young (3.11±0.67 and 3.46±1.11, right and left upper central incisors, respectively) compared to middle age (1.93±0.47 and 2.30±0.64, right and left upper central incisors, respectively) participants (independent sample t test; p lt 0.05). There was no correlation between common and external carotid artery blood flow and upper central incisors PBF in young as well as middle age participants, for right or left side. Conclusion Absence of correlation between carotid arteries blood flow and PBF suggests that reduced PBF in middle age participants was probably not due to reduced blood supply from carotid arteries but it was result of age related changes at the level of pulpal blood vessels., Uvod Vaskularna mreža zubne pulpe dobija dotok krvi preko zajedničke i spoljašnje karotidne arterije i završnih zubnih grana koje snabdevaju svaku pojedinačnu pulpu.

AB  - Introduction Calcium silicate cements can be successfully used for the treatment of root perforations due to their exceptional biological and sealing properties. The aim of this study was to test, using dye penetration method, marginal microleakage of newly synthesized nanostructured biomaterials based on calcium silicate system and hydroxyapatite after their application in interradicular perforation of extracted teeth. Material and Methods The study included 34 extracted human molars. Newly synthesized nanostructured materials: one based on calcium silicate system (CS), and the other one based on hydroxyapatite and active calcium silicate system (HA-CS) were tested. Mineral trioxide agreaggate (MTA; Angelus, Londrina, Brazil) was used as control. Marginal microleakage was evaluated using dye penetration test 6 months after the application of materials in experimentally prepared inter-radicular perforations in extracted human molars. Dye penetration was analyzed using light microscope at 30X magnification, a method of quantifying visual information in computer software for image processing (Adobe Photoshop CS5 Extended, version 12.0 x 32). The values were expressed in millimeters, and the results statistically analyzed using one-way ANOVA and Tukey post-hoc test (α=0.05). Results The shortest dye penetration was measured for calcium silicate system (0.44 mm), while slightly higher values were found for MTA (0.54 mm). Dye penetration for hydroxyapatite and active calcium silicate system (2.00 mm) was longer than for the other two materials (p lt 0.05). Conclusion The lowest marginal microleakage was observed in CS and was comparable to MTA. Microleakage in HA-CS was significantly higher than CS and MTA.

Zaključak Najmanja marginalna mikropropustljivost zabeležena je kod materijala CS i bila je komparabilna sa MTA. Mikropropustljivost materijala HA-CS bila je značajno veća u odnosu na materijal CS i kontrolni materijal MTA.

AB  - Introduction. Acute periapical inflammation is the most common cause of postoperative pain developing as a result of mechanical, chemical and/or microbial injury of periapical tissue. The major inflammatory event responsible for periapical pain is increased vasodilatation and vascular permeability, partly caused by prostaglandin E2, with consequent edema, which leads to the compression of nerve fibers. Objective. The aim of this study was to determine the concentrations of prostaglandin E2 in apical tissue fluid after endodontic treatment of intact and teeth with large restorations and to compare it with the occurrence and intensity of postoperative pain. Methods. Single-rooted teeth of 24 patients, selected for this study, were distributed into two groups: intact (group 1, n=27) and asymptomatic teeth with large restorations (group 2, n=20). Clinical examination of the involved teeth included the electric pulp test, recording pain on percussion, spontaneous pain, and a radiographic examination. Samples of apical tissues fluid were obtained from root canals at two treatment visits, and prostaglandin E2 concentrations were measured using radioimmunoassay. Pain intensity was assessed by visual analogue scale. Results. Prostaglandin E2 concentrations at the second visit, in teeth with large restorations, was significantly higher (36%) than at the first treatment visit (Wilcoxon signed rank test, p lt 0.05). Occurrence and intensity of spontaneous pain after the first visit were significantly higher in group 2 (p lt 0.05) than in group 1. Conclusion. These results suggest that the increased prostaglandin E2 concentration, caused by endodontic treatment of teeth with large restorations, is well correlated with the intensity of postoperative pain.
AB  - Uvod. Akutno periapikalno zapaljenje je najčešći uzrok postoperacionog bola koji se javlja kao rezultat mehaničke, hemijske i/ili mikrobne povrede periapikalnog tkiva. Glavni zapaljenjski proces odgovoran za periapikalni bol je povećana vazodilatacija i vaskularna propustljivost, delimično uzrokovana prostaglandinom E2, s posledičnim edemom, što dovodi do kompresije nervnih vlakana. Cilj rada. Cilj rada je bio da se utvrdi koncentracija prostaglandina E2 u tečnosti apikalnog tkiva posle endodontskog lečenja intaktnih i zuba s velikim restoracijama, a zatim uporedi s pojavom i intenzitetom postoperacionog bola. Metode rada. Jednokoreni zubi 24 odabrana pacijenta svrstani su u dve grupe: intaktni zubi (grupa 1, 27 zuba) i asimptomatski zubi s velikim restoracijama (grupa 2, 20 zuba). Klinički pregled zuba sastojao se od elektrotesta, registrovanja bola na perkusiju ili spontanog bola i radiografskog ispitivanja. Uzorci tečnosti apikalnog tkiva sakupljani su iz kanala korena tokom dve posete stomatologu, a koncentracija prostaglandina E2 merena je radioimunoesej analizom. Intenzitet bola je određivan na vizuelnoj analognoj skali. Rezultati. Koncentracija prostaglandina E2 kod zuba s velikim restoracijama prilikom druge posete bila je značajno veća (36%) nego tokom prve posete (Vilkoksonov test, p lt 0,05). Intenzitet spontanog bola posle prve posete bio je značajno veći u grupi 2 (p lt 0,05) nego u grupi 1. Zaključak. Rezultati pokazuju da je povećana koncentracija prostaglandina E2 uzrokovana endodontskim lečenjem zuba s velikim restoracijama u korelaciji s intenzitetom postoperacionog bola.

AB  - Introduction: The skin microcirculation is significantly affected by serum estrogen levels. The objective of this study was to investigate the effects of estrogen serum level changes associated with the menstrual cycle and postmenopause on dental pulp blood flow (PBF) as well as its dynamics. Methods: Young women at the menstrual phase (low serum estrogen levels) and in the mid-cycle phase of the menstrual cycle (high serum estrogen levels) and postmenopausal women were enrolled in the study. PBF and its oscillations were measured by laser Doppler flowmetry and analyzed by using wavelet transform. Serum levels of estradiol-17 beta were measured by immunoassay. Results: PBFs of young women in the menstrual phase and postmenopausal women were mutually similar and significantly lower than those of young women in the mid-cycle period. With respect to the mid-cycle phase, relative amplitude and power were significantly increased in the interval 0.0095-0.02 Hz and decreased in the intervals 0.02-0.06 and 0.06-0.2 Hz in the menstrual phase. A significant decrease in 0.0095-0.02 Hz and increase in 0.02-0.06, 0.06-0.2, 0.2-0.6, and 0.6-1.6 Hz intervals were observed in postmenopause. Conclusions: The study has shown that the menstrual phase of the menstrual cycle and postmenopause have similar PBF decrease, but PBF oscillations are differently affected in the mid-cycle phase.

AB  - Dental pulp represents a microcirculatory sistem which due to localization within dentinal walls has specific characteristics. Major feeding blood vesels of dental pulp, as well as orofacial region, are common carotid artery (CCA) and external carotid artery (ECA). Carotid arteries, like dental pulp microcirculation, undergo different structural and functional age-related changes. It has been shown that physiological changes in plasma estrogen levels during the menstrual cycle, and postmenopause, significantly affect blood flow in the microcirculatory system of the brain and skin. In pathological conditions, in presence of carotid atherosclerosis, there are significant changes in blood flow in tissues they supply. Having all this in mind, it was hypothesized that age, estrogen status and carotid atherosclerosis significantly affect blood flow in the dental pulp. The aims of this study were to: 1. Determine dental pulp blood flow and blood flow through the CCA and ECA and intima-media thickness (IMT) of these arteries in healthy adults of both sexes in two age groups of 20-25 and 50-60 years (general population); 2. Examine the dependence of dental pulp blood flow, the flow through the CCA and ECA, and IMT of these arteries in relation to age in the general population; 3. Examine the correlation between dental pulp blood flow and flow through the CCA and ECA and IMT of these arteries in the general population; 4. Determine dental pulp blood flow and estrogen levels in healthy women aged 20-25 years during the regular menstrual cycle (which is 28 days), at a phase when estrogen is high (from 10 to 13 days) and a phase when estrogen is low (from 26 to 5 days), and in postmenopausal women; 5. Examine the correlation between dental pulp blood flow and estrogen levels in women with regular menstrual cycle and postmenopausal women...
AB  - Zubna pulpa predstavlja mikrocirkulatorni sistem koji zbog svoje lokalizacije unutar čvrstih dentinskih zidova ima posebne karakteristike. Glavni dovodni krvni sudovi za zubnu pulpu, kao i druge organe i tkiva orofacijalne regije, su zajednička karotidna arterija (ZKA) i spoljašnja karotidna arterija (SKA). Karotidne arterije, kao i mikrocirkulacija zubne pulpe starenjem podležu različitim strukturnim i funkcionalnim promenama. Pokazano je da fiziološke promene nivoa estrogena u plazmi tokom menstrualnog ciklusa, kao i u menopauzi, značajno utiču na protok krvi u mikrocirkulatornim sistemima mozga i kože. U patološkim uslovima, u prisustvu ateroskleroze karotidnih arterija, postoje značajne promene u protoku krvi u tkivima koja one ishranjuju. Imajući sve ovo u vidu postavljena je hipoteza da životna dob, estrogenski status i ateroskleroza karotidnih arterija značajno utiču na protok krvi u zubnoj pulpi. Ciljevi ovog istraživanja bili su: 1. Odrediti protok krvi kroz krvne sudove zubne pulpe i protok kroz ZKA i SKA kao i debljinu intimo-medijalnog kompleksa (IMK) pomenutih arterija kod zdravih osoba, oba pola, u dve starosne grupe, od 20-25 i od 50- 60 godina (opšta populacija); 2.

AB  - Emerging technologies and new nanoscale information have potential to transform dental practice by improving all aspects of diagnostics and therapy. Nanocharacterization allows understanding of oral diseases at molecular and cellular levels which eventually can increase the success of prevention and treatment. Opto-magnetic spectroscopy (OMS) is a promising new technique based on light-matter interaction which allows insight into the quantum state of matter. Since biomolecules and tissues are usually paramagnetic or diamagnetic materials it is possible to determine the dynamics of para-and diamagnetism at different teeth structures using that method. The topography of the surface of a sample can be obtained with a very high resolution using atomic force microscopy (AFM), which allows observation of minimal changes up to 10 nm, while magnetic force microscopy (MFM) is used to record the magnetic field gradient and its distribution over the surface of a sample. The aim of this study was to determine the possibility of AFM and MFM for the characterization of dental calculus, and a potential application of OMS for the detection of subgingival dental calculus.

AB  - Introduction. The function of root canal fillings is to seal the root canal system. The important physical property necessary for sealers to achieve this is low solubility. However, any therapeutic effect of calcium hydroxide-based sealers is dependent on the calcium hydroxide being in ionized form, which implies that the material must be at least partly soluble. Objective. The objective of our study was to compare weight changes of Acroseal and Apexit, conventional calcium hydroxide-based sealer and AH Plus, epoxy-amine resin sealer in Hank's solution at different exposure times. Methods. The standardized samples of each material were weighed and immersed in the Hank's solution for 1 h, 24 h, 96 h, 14 days and 28 days. After these exposure times, they were removed, dried, and weighed again. Mean weight changes were determined and the differences between sealers were analysed statistically using a one-way ANOVA. Results. The highest differences in mass were observed in Apexit, 1.52%, and were significantly different from Acroseal, 0.93% (p lt 0.05) and AH Plus, 0.45% (p lt 0.05). There were no significant differences between Acroseal and AH Plus, except for 96 h period. Conclusion. Under the conditions of our study, it may be concluded that the Acroseal sealer presented the behaviour more like epoxy-based material, AH Plus, than calcium hydroxide sealer, Apexit.

Međutim, terapijski efekat silera na bazi kalcijum-hidroksida zavisi od jonizovanosti ovog jedinjenja, što znači da materijal mora biti bar delimično rastvorljiv. Cilj rada. Cilj istraživanja bio je da se uporedi promena mase pasti Acroseal i Apexit, kao konvencionalnih silera na bazi kalcijum-hidroksida, i paste AH Plus, kao silera koji se sastoji od epoksiamin smole, u Henkovom rastvoru pri različitim vremenima izlaganja. Metode rada. Standardizovani uzorci svakog materijala mereni su i potapani u Henkov rastvor na jedan sat, 24 sata, 96 sati, 14 dana i 28 dana. Posle ovih vremenskih intervala uzorci su izvađeni iz rastvora, sušeni i ponovo mereni. Razlike između srednjih vrednosti promene mase silera statistički su analizirane primenom jednosmernog ANOVA testa. Rezultati. Najveća razlika u masi uočena je kod paste Apexit (1,52%), koja je bila statistički značajno veća nego kod pasti Acroseal (0,93%; p lt 0,05) i AH Plus (0,45%; p lt 0,05). Statistički značajne razlike između silera Acroseal i AH Plus nije bilo, izuzev za period od 96 sati. Zaključak. Naše istraživanje je pokazalo da se Acroseal ponaša sličnije sileru baziranom na epoksiamin smoli (AH Plus), nego pasti na bazi kalcijum-hidroksida (Apexit).

Razlike između srednjih vrednosti promene mase silera statistički su analizirane primenom jednosmernog ANOVA testa. Rezultati. Najveća razlika u masi uočena je kod paste Apexit (1,52%), koja je bila statistički značajno veća nego kod pasti Acroseal (0,93%; p lt 0,05) i AH Plus (0,45%; p lt 0,05). Statistički značajne razlike između silera Acroseal i AH Plus nije bilo, izuzev za period od 96 sati. Zaključak. Naše istraživanje je pokazalo da se Acroseal ponaša sličnije sileru baziranom na epoksiamin smoli (AH Plus), nego pasti na bazi kalcijum-hidroksida (Apexit).",

AB  - Laser Doppler is a noninvasive, objective, reproducible and painless method for measuring blood flow in tissue microcirculation. This method is based on the Doppler effect, the change in frequency of light reflecting from blood cells in motion. Light from helium-neon laser through optical fibers and probes is directed to the surface of the tissue in which the flow is measured. Light portion is reflected from the cells in motion and changes the frequency while another portion is reflected from the static tissue maintaining the same frequency as the initial light. The total reflected light, with changed and original frequency, reaches photo detector in the same probe where the emitter is and it is transformed into electrical impulse. In the orofacial region the laser Doppler method is used to examine blood flow in the mandible, teeth pulp and masticator muscles. A significant drawback of the laser Doppler method is its sensitivity to the ambient conditions during measuring and the fact that blood flow is measured in all blood vessels of examined microregion. Therefore, the circulation of isolated individual blood vessels can not be monitored. Laser Doppler method can give reliable indicators of blood flow in mouth tissue and method is acceptable for the patients.
AB  - Laser dopler floumetrija je neinvazivna, objektivna, reproduktibilna i bezbolna metoda merenja protoka krvi na nivou mikrocirkulacije tkiva. Metoda je zasnovana na promeni frekvencije svetlosti pri odbijanju od krvnih ćelija u pokretu, odnosno na Doplerovom efektu. Svetlost helijum- neonskog lasera se putem optičkih vlakana i sonde s emiterom usmerava na površinu tkiva u kojem se ispituje protok. Deo svetlosti se odbija od ćelija u pokretu, pri čemu menja frekvenciju, a drugi deo svetlosti se odbija od statičnih tkiva zadržavajući istu frekvenciju kao i upadna svetlost. Ukupna odbijena svetlost s promenjenom i nepromenjenom frekvencijom dospeva do fotodetektora, koji je u okviru iste sonde kao i emiter, i pretvara se u električni impuls. U orofacijalnoj regiji laser dopler metoda je korišćena za ispitivanje protoka krvi u mandibuli, protoka u pulpi humanih zuba i u mastikatornim mišićima. Značajan nedostatak ove metode je njena osetljivost na uticaje iz okoline, kao i činjenica da se protok krvi meri u svim krvnim sudovima ispitivane mikroregije, pa se ne može izolovano pratiti cirkulacija u pojedinačnim krvnim sudovima. Ovom metodom se mogu dobiti pouzdani pokazatelji protoka krvi u tkivima usne duplje, a pacijenti je dobro prihvataju.

AB  - Supernumerary teeth are defined as any supplementary tooth in addition to usual configuration of twenty deciduous and thirty-two permanent teeth. They are most commonly found in the anterior maxilla and mandibular bicuspid region. Although supernumerary teeth have been reported in the incisor region of the mandible, they are very rare. It has been confirmed that approximately 25% of permanent supernumerary teeth appear in the mouth, the rest remains unerupted. The aim of this study was to present a case of single, erupted, supernumerary tooth in the right incisal region of the mandible. A patient showed up at the dental office complaining about aesthetic problem caused by a supernumerary tooth in mandibular incisal region. On intraoral examination, a supernumerary tooth, conical in shape and labially positioned, between the tooth 42 and 43, was observed. On previously taken panoramic radiogram, six months ago, the supernumerary tooth was undetected. Because the supernumerary tooth was masked by the denser overlying cortical bone, it was difficult to interpret the radiogram correctly. It should be noted that panoramic radiography does not guarantee accurate diagnosis of supernumerary teeth, therefore additional diagnostic methods are required.
AB  - Kao prekobrojni može se definisati svaki zub koji se javi kao višak u odnosu na uobičajenu konfiguraciju od dvadeset mlečnih zuba i trideset dva stalna zuba. Prekobrojni zubi se najčešće javljaju u prednjem delu gornje vilice i predelu pretkutnjaka donje vilice. Iako su poznati slučajevi prekobrojnih zuba u predelu sekutića donje vilice, oni se retko javljaju. Pokazano je da oko 25% prekobrojnih zuba stalne denticije niče, dok ostali ostaju impaktirani. Cilj ovog rada je bio da se kod odraslog muškarca prikaže slučaj prekobrojnog zuba koji je iznikao u predelu sekutića donje vilice. Pacijent se javio zbog estetskih problema izazvanih dodatnim nicanjem donjeg prednjeg zuba. Intraoralno, u predelu između zuba 42 i 43, mogao se uočiti labijalno pozicioniran prekobrojni zub koničnog oblika. Na ortopantomogramu načinjenom šest meseci ranije ovaj prekobrojni zub nije zapažen. S obzirom na to da se prekobrojni zub superponirao s kortikalnom kosti, bilo je otežano ispravno tumačenje snimka. S obzirom na to da ortopantomografski snimci ne garantuju uvek preciznu dijagnozu prekobrojnih zuba, za kliničku dijagnozu je neophodno preduzeti i dodatne dijagnostičke postupke.

AB  - Light-curing of resin-based composites (RBCs) is associated with temperature increase in the pulp chamber, which may have a detrimental effect on the vital pulp. The purpose of the study was to evaluate temperature changes of silorane-, ormocer-, and dimethacrylate-based RBCs at the bottom surface of the RBC and in the pulp chamber roof dentin (PCRD) during curing. In part A, temperatures were measured for Filtek LS (3M ESPE, St. Paul, MN, USA), Admira (Voco GmbH, Cuxhaven, Germany), and Herculite XRV (Kerr Corp., Orange, CA, USA) with a high-power light-emitting diode (LED) unit by placing thermocouples in contact with the bottom surface of the material in standardized acrylic molds. In part B, temperature changes in PCRD were measured in extracted molars during light-curing of adhesives and RBCs in 2-mm-deep cavities with a remaining dentin thickness (RDT) of 1 mm. Filtek LS showed a different temperature curve compared with Admira and Herculite XRV. Significantly higher temperatures were recorded for Filtek LS (p  lt  0.001) than for Admira and Herculite XRV in acrylic molds. Temperature rises recorded in PCRD for adhesives and RBCs were between 4.1 and 6.4 degrees C. No significant differences in PCRD temperatures were found between the three groups during adhesive curing and RBC curing (p > 0.05). Filtek LS showed a different heat-generation pattern from and significantly higher temperatures than Admira and Herculite XRV when the materials were tested in acrylic molds. Similar temperatures were recorded in the PCRD during curing of adhesives and RBCs. Although a substantial temperature rise in the bulk material occurred during light-curing of the three resin-based composites, a remaining dentin thickness of 1 mm caused a significant reduction in pulp chamber roof dentin temperatures. Temperatures measured in the pulp chamber roof dentin corresponding to the zone occupied by the postmitotic odontoblast layer were not statistically different for the three types of resin-based composites.
