AB  - Background/Aim. Discoloration of dental restorations makes them aesthetically unacceptable and is a frequent reason for replacement of composite restorations. The aim of this study was to evaluate changes of color and fluorescence of resin-based composites (RBCs) exposed to natural juices and energy drinks. Methods. Microhybrid composite Gradia Direct (TM) Extra Bleach White disc-shaped specimens (n = 35) were immersed in three different natural juices and four different energy drinks. Absorption spectra of natural juices and energy drinks, diffuse reflection and fluorescence of composite samples were measured prior and after seven-day immersion by spectrophotometer Thermo Evolution 600 and spectrofluorometer Fluorolog-3-221. Composite's color was calculated from diffuse reflection spectra and expressed in CIELAB color space (Commission International de l'Eclairage). Results. All natural juices and energy drinks induced color change of resin based composites, but to the different extent. Only aronia and carrot juices induced total color change considerably higher than clinically acceptable threshold, 9.3 and 6.2, respectively. All energy drinks and aronia juice induced notable decrease in fluorescence; the highest change of 28% was evidenced in the case of aronia juice. Conclusion. Change of color and fluorescence will appear differently with various solutions due to different chemical composition and concentration of colorant species in different beverages. Solutions with higher optical absorption induced higher total color change. Discoloration of composites in aronia and carrot juices is similar to those earlier reported for red wine, tea and coffee.

AB  - This study correlated the refractive indices (RIs) of unfilled resin mixtures and resin-based composites (RBCs) with color and translucency of conventional and low-shrinkage RBCs. Unfilled resin mixtures based on different ratios of conventional monomers Bisphenol A-glycidyl-methacrylate (BisGMA)/triethyleneglycol-dimethacrylate (TEGDMA) and urethane-dimethacrylate (UDMA)/TEGDMA and a low-shrinkage monomer FIT-852 (FIT, Esstech Inc.)/TEGDMA were used to prepare model RBCs, containing 30 wt % of the organic matrix and 70 wt % of silanated barium-glass fillers (n=1.553, Esstech Inc.). The RIs of resins were measured on an ABBE refractometer, those of cured RBCs using the Becke-line method in immersion oils. Color and translucency were determined using an AvaSpec-2048 (Avantes BV) spectrometer. The RIs of unfilled resin mixtures decreased with increasing amounts of TEGDMA. Cured RBCs had higher RIs than their respective resin mixtures. BisGMA-based composites were more translucent with significantly lower L* values than FIT- and UDMA-based RBCs. The RIs of unfilled resins positively correlated with cured RBCs (p=0.001), as did the RIs with translucency (p=0.001) and color (p=0.008). Resin mixtures and corresponding RBCs based on UDMA and its modified low-shrinkage version, FIT, showed similar optical properties. The RIs of unfilled resins appeared to be good predictors of the RIs of cured RBCs.

AB  - Objective. To compare cytotoxicity and genotoxicity of novel urethane-based monomer FIT-852 and monoacylphosphine oxide photoinitiator (Lucirin TPO) with conventional Bisphenol A-glycidyl-methacrylate (BisGMA) and triethylene glycol dimethacrylate (TEGDMA) monomers and camphorquinone (CQ)/amine photoinitiator system, respectively. Moreover, we quantified and analyzed the combinatorial effects of individual substances in resin-based mixtures concerning the nature of the combinatorial effects. Methods. Cytotoxic and genotoxic effects of BisGMA, FIT, TEGDMA, CQ DMAEMA and TPO and their combined toxicity in four clinically relevant mixtures (FIT/TPO, FIT/CQ BisGMA/TPO, BisGMA/CQ) were tested on human fetal lung fibroblasts MRC-5 using MTT and Comet assays. We assessed combination effects of monomers and photoinitiators on overall toxicity from the measured concentration-effect relationships. Combination index (CI) was calculated on the basis of the median-effect equation derived from the mass-action law principle. Results. Individual substances showed decreasing cytotoxic effects in the following order: BisGMA>TPO>FIT>CQ>DMAEMA>TEGDMA. Experimental mixtures showed decreasing cytotoxic effects in the order BisGMA/TPO>BisGMA/CQ>FIT/CQ>FIT/TPO. FIT-based mixtures exhibited antagonistic cytotoxic effects between components while BisGMA-based mixtures demonstrated synergistic effects at ED50 TPO amplified both antagonistic and synergistic cytotoxic effects in mixtures. Pure substances showed genotoxicity in the following order: TPO>BisGMA>FIT>CQ>TEGDMA. We did not detect the genotoxic potential of DMAEMA. The rank of genotoxic concentrations of the mixtures was: BisGMA/TPO>BisGMA/CQ>FIT/CQ>FIT/TPO. Significance. Lower cytotoxicity and genotoxicity of FIT than BisGMA suggests its greater bio-co mpatibility. Conversely, photoinitiator TPO was significantly more cytotoxic and genotoxic than both CQ and DMAEMA. CI values showed that components of FIT-based mixtures exhibit an antagonistic cytotoxic effect, while compontents of BisGMA-based mixtures show synergism.

AB  - Objective. To study the effect of a low-shrinkage methacrylate monomer and monoacylphosphine oxide photoinitiator on color, translucency, and color stability of model resin-based composites (RBCs). Methods. Four micro-hybrid RBCs were prepared containing barium-glass fillers in bisphenol A-glycidyl-methacrylate (BisGMA) and triethyleneglycol-dimethacrylate (TEGDMA) or urethane-based low-shrinkage monomer FIT-852 (FIT; Esstech Inc.) and TEGDMA matrix. Camphorquinone (CQ)/amine or Lucirin TPO were used as photoinitiators. Commercial low-shrinkage RBCs (Charisma Diamond, Heraeus Kulzer and N'Durance, Septodont) and conventional RBCs (Tetric EvoCeram, Ivoclar Vivadent and Filtek Z250, 3M ESPE) were used as controls. Color and translucency were measured using Thermo Scientific Evolution (Thermo Fisher Scientific) and SpectroShade (TM) Micro (MHT Optic Research) spectrophotometers. Color stability was evaluated after immersion in black tea (pure, with milk or lemon) and distilled water. Data were analyzed using analyses of variance with Tukey's post-test (alpha = 0.05). Results. Photoinitiators had no significant effect on baseline color. Initially whiter FIT-based RBCs showed greater staining in all staining solutions than BisGMA-based RBCs. TPO-containing RBCs showed better color stability than CQ-containing RBCs irrespective of the base monomer. Tea and tea with lemon induced greatest color changes. Adding milk to tea significantly reduced material staining. Significance. Urethane-based low-shrinkage monomer FIT and conventional BisGMA affected color, translucency and color stability of their respective RBCs. Despite being used in posterior teeth, low-shrinkage RBCs are expected to have favorable optical and esthetic properties. Manufacturers are urged to provide information on optical properties of monomers and monomer mixtures in their low-shrinkage RBCs to allow understanding of interaction with fillers and photoinitiators.

AB  - This study investigated the degree of conversion, depth of cure, Vickers hardness, flexural strength, flexural modulus and volumetric shrinkage of experimental composite containing a low shrinkage monomer FIT-852 (FIT; Esstech Inc.) and photoinitiator 2,4,6-trimethylbenzoyldiphenylphosphine oxide (TPO; Sigma Aldrich) compared to conventional composite containing Bisphenol A-glycidyl methacrylate (BisGMA) and camphorquinone-amine photoinitiator system. The degree of conversion was generally higher in FIT-based composites (45-64% range) than in BisGMA-based composites (34-58% range). Vickers hardness, flexural strength and modulus were higher in BisGMA-based composites. A polywave light-curing unit was generally more efficient in terms of conversion and hardness of experimental composites than a monowave unit. FIT-based composite containing TPO showed the depth of cure below 2 mm irrespective of the curing light. The depth of cure of FIT-based composite containing CQ and BisGMA-based composites with either photoinitiator was in the range of 2.8-3.0 mm. Volumetric shrinkage of FIT-based composite (0.9-5.7% range) was lower than that of BisGMA-based composite (2.2-12% range). FIT may be used as a shrinkage reducing monomer compatible with the conventional CQ-amine system as well as the alternative TPO photoinitiator. However, the depth of cure of FIT_TPO composite requires boosting to achieve clinically recommended thickness of 2 mm.

AB  - Objective. To compare strain and displacement of sculptable bulk-fill, low-shrinkage and conventional composites as well as dye penetration along the dentin-restoration interface. Methods. Modified Class II cavities (N= 5/group) were filled with sculptable bulk-fill (Filtek Bulk Fill Posterior, 3M ESPE; Tetric EvoCeram Bulk Fill, Ivoclar Vivadent; fiber-reinforced EverX Posterior, GC; giomer Beautifil Bulk, Schofu), low-shrinkage (Kalore, GC), nanohybrid (Tetric EvoCeram, Ivoclar Vivadent) or microhybrid (Filtek Z250, 3M ESPE) composites. Strain and displacement were determined using the 3D digital image correlation method based on two cameras with 1 mu m displacement sensitivity and 1600 x 1200 pixel resolution (Aramis, GOM). Microleakage along dentin axial and gingival cavity walls was measured under a stereomicroscope using a different set of teeth (N = 8/group). Data were analyzed using analyses of variance with Tukey's post-test, Pearson correlation and paired t-test (alpha = 0.05). Results. Strain of TEC Bulk, Filtek Bulk, Beautifil Bulk and Kalore was in the range of 1-1.5%. EverX and control composites showed 1.5-2% strain. Axial displacements were between 5 mu m and 30 mu m The least strain was identified at 2 mm below the occlusal surface in 4-mm but not in 2-mm layered composites. Greater microleakage occurred along the gingival than axial wall (p  lt  0.05). No correlation was found between strain/displacements and microleakage axially (r(2) = 0.082, p = 0.821; r(2) =-0.2, p = 0.605, respectively) or gingivally (r(2) =-0.126, p = 0.729, r(2) =-0.278, p = 0.469, respectively). Significance. Strain i.e. volumetric shrinkage of sculptable bulk-fill and low-shrinkage composites was comparable to control composites but strain distribution across restoration depth differed. Marginal integrity was more compromised along the gingival than axial dentin wall.

AB  - ObjectiveThe aim of this study was to evaluate changes of color and fluorescence of resin based composite exposed to beer. Materials and Methods84 samples (13 mm in diameter and 1.5 mm thick) of microhybrid composite Gradia Direct(TM) extra bleach white were immersed in 5 different beers (dark and light) or distilled water. Color and fluorescence were measured prior and after 1-, 7-, and 14-day immersion by Spectrophotometer Thermo Evolution 600 and Fluorolog-3-221 spectrofluorometer. ResultsResin based composites changed color after immersion in beers of different types. Beers with higher optical absorption induced greater color changes. The fluorescence intensity of composites was decreased after immersion in beer, but the shape of fluorescence spectra was not changed. 14-day immersion in Bernard dark beer caused the greatest changes in optical properties of composite: E*=9.0 and 57.6% reduced fluorescence. ConclusionDark and light beers changed optical properties of resin based composite. The color change come exclusively from the change of chroma. Clinical SignificanceTo fully meet esthetic criteria when using dental materials in restoration it is crucial to match optical properties of teeth and dental restoration at the moment of placement, but also to keep the match over the time. Considering that staining in beer causes changes in color and fluorescence of composites and that discoloration is a frequent reason for replacement of composite restorations, the data and conclusions on discoloration of dental restorations caused by beer consumption should aid dental professionals when reaching for high esthetics of modern dentistry.(J Esthet Restor Dent 28:330-338, 2016)

AB  - Colour changes in Gradia Direct (TM) composite after immersion in tea, coffee, red wine, Coca-Cola, Colgate mouthwash, and distilled water were evaluated using principal component analysis (PCA) and the CIELAB colour coordinates. The reflection spectra of the composites were used as input data for the PCA. The output data (scores and loadings) provided information about the magnitude and origin of the surface reflection changes after exposure to the staining solutions. The reflection spectra of the stained samples generally exhibited lower reflection in the blue spectral range, which was manifested in the lower content of the blue shade for the samples. Both analyses demonstrated the high staining abilities of tea, coffee, and red wine, which produced total colour changes of 4.31, 6.61, and 6.22, respectively, according to the CIELAB analysis. PCA revealed subtle changes in the reflection spectra of composites immersed in Coca-Cola, demonstrating Coca-Cola's ability to stain the composite to a small degree.

AB  - Objective. To determine the shear bond strength (SBS) between synthetic controlled porous hydroxyapatite (HAP) inserts and restorative materials and dimensional changes of insert-containing restorations during curing. Methods. Cylinder-shaped HAP inserts (4 mm in diameter, 1.6 mm thick) were cemented in dentin discs (5 mm x 1.6 mm), cut mid-coronally from human third molars, using one of the following materials: universal microhybrid composite Filtek Z250, flowable composite Filtek Ultimate or glass-ionomer Vitrebond (all 3M ESPE). SBS of the same materials to HAP inserts was tested in a universal testing machine. Three-dimensional digital image correlation system Aramis (GOM) was used to measure strains and displacements. Data were statistically analyzed using one-way ANOVA with Tukey's post-test (alpha = 0.05). Results. SBS of restorative materials to HAP inserts ranged between 12.2 +/- 2.1 MPa (Filtek Z250) and 0.7 +/- 0.4 MPa (Filtek Z250 without an adhesive). The 'total-etch' approach of adhesive application significantly increased SBS of both Filtek Z250 (12.2 +/- 2.1 MPa) and Filtek Ultimate flowable (9.5 +/- 2.5 MPa) compared to the 'self-etch' approach (8.2 +/- 1.6 MPa and 4.4 +/- 0.9 MPa, respectively) (p  lt  0.05). HAP inserts reduced polymerization shrinkage to below 0.5% as well as displacements in the central region of the restorations. Peripheral shrinkage of restorative materials was similar with and without HAP inserts as were displacements of Filtek Z250 and Vitrebond. Significance. Replacing major part of dentin clinically, especially in large cavities, HAP inserts may shorten clinical working time, improve dimensional stability of the restoration by reducing central shrinkage and displacements and provide adhesive bonding to universal composites following a 'total-etch' approach.

AB  - Elution of potentially toxic substances, including monomers, from resin-based dental composites may affect the biocompatibility of these materials in clinical conditions. In addition to the amounts of eluted monomers, mathematical modeling of elution kinetics reveals composite restorations as potential chronic sources of leachable monomers. The aim of this work was to experimentally quantify elution of main cross-linking monomers from four commercial composites and offer a mathematical model of elution kinetics. Composite samples (n = 7 per group) of Filtek Supreme XT (3M ESPE), Tetric EvoCeram (Ivoclar Vivadent), Admira (Voco), and Filtek Z250 (3M ESPE) were prepared in 2-mm thick Teflon moulds and cured with halogen or light-emitting diode light. Monomer elution in ethanol and water was analyzed using high-performance liquid chromatography up to 28 days postimmersion. The mathematical model was expressed as a sum of two exponential regression functions representing the first-order kinetics law. Elution kinetics in all cases followed the same mathematical model though differences in rate constants as well as the extent of monomer elution were material-, LCU-, medium-dependent. The proposed mechanisms of elution indicate fast elution from surface and subsurface layers and up to 100 times slower monomer extraction from the bulk polymer.

AB  - Objective: To analyze local shrinkage patterns in terms of surface shrinkage strains and z-axis displacements in a novel self-adhering composite and a conventional flowable composite using three-dimensional digital image correlation. Method and Materials: Seven samples of each material were prepared in cylindrical Teflon molds 5 mm in diameter and 2 mm thick. The surface of the composites facing the cameras was sprayed with a fine layer of black paint. The unsprayed surface of each sample, opposite the one facing the cameras, was light cured for 40 seconds using a light-emitting diode unit. Digital images were taken immediately before and after light curing. Shrinkage was calculated as von Mises strains, and z-axis displacements were measured in microns. The data were statistically analyzed using two-way ANOVA at alpha = .05. Results: No significant difference in strain was observed between the two materials (P > .05). Strain distribution was nonhomogenous-the outer segments showed significantly higher strains than central parts in each material (P  lt  .05).

abstract = "Objective: To analyze local shrinkage patterns in terms of surface shrinkage strains and z-axis displacements in a novel self-adhering composite and a conventional flowable composite using three-dimensional digital image correlation. Method and Materials: Seven samples of each material were prepared in cylindrical Teflon molds 5 mm in diameter and 2 mm thick. The surface of the composites facing the cameras was sprayed with a fine layer of black paint. The unsprayed surface of each sample, opposite the one facing the cameras, was light cured for 40 seconds using a light-emitting diode unit. Digital images were taken immediately before and after light curing. Shrinkage was calculated as von Mises strains, and z-axis displacements were measured in microns. The data were statistically analyzed using two-way ANOVA at alpha = .05. Results: No significant difference in strain was observed between the two materials (P > .05). Strain distribution was nonhomogenous-the outer segments showed significantly higher strains than central parts in each material (P  lt  .05). The opposite was observed for z-axis displacements-significantly greater displacements were found in central parts compared to the outer segments (P  lt  .05). Conclusion: Different shrinkage vectors across the surface of the tested flowable composites showed predominant in-plane shrinkage of the outer surface segments and out-of-plane shrinkage of the inner segments.

AB  - Objectives. To study monomer elution from four resin-based composites (RBCs) cured with different light sources. Methods. Twenty-eight premolars were randomly allocated to four groups. Standardized cavities were prepared and restored with a nanohybrid (Filtek Supreme XT or Tetric EvoCeram), an ormocer (Admira) or a microhybrid RBC (Filtek Z250) which served as control. Buccal restorations were cured with a halogen and oral restorations with an LED light-curing unit. Elution of diurethane dimethacrylate (UDMA), Bisphenol A diglycidylether methacrylate (BisGMA), triethylene glycol dimethacrylate (TEGDMA) and 2-hydroxyethyl methacrylate (HEMA) was analyzed using high-performance liquid chromatography (HPLC) 1h to 28 days post-immersion in 75% ethanol. Data were analyzed using multivariate and repeated measures analysis of variance (alpha = 0.05). Results. The greatest elution of UDMA and BisGMA occurred from Tetric EvoCeram and the least from Filtek Z250 (p  lt  0.05). LED and halogen light-curing units gave similar results for all RBCs (p > 0.05) except Tetric EvoCeram which showed greater elution for the LED unit (p  lt  0.05). TEGDMA was below the limit of quantification. HEMA eluted in similar concentrations from Filtek Supreme and Tetric EvoCeram (p > 0.05). Significance. : The two nanohybrid RBCs eluted more cross-linking monomers than the ormocer and the control microhybrid RBC. Continuous elution over 28 days indicates that RBCs act as a chronic source of monomers in clinical conditions. Light source may affect monomer elution since differences were found for one out of four RBCs. Mathematical models for elution kinetics of UDMA and BisGMA indicated two elution mechanisms.

AB  - Polymerization shrinkage is the single most important local deformation of dental composites that has a substantial effect on the quality of the tooth-restoration interface in clinical conditions. The aim of this study was to investigate the possibility to analyze local deformation fields of a dental composite upon polymerization using the 3D optical method of digital image correlation with two cameras. Conventional, microhybrid composite samples were prepared in custom-made Teflon molds and polymerized with a conventional halogen light. Local deformation fields were determined using the two-camera system, Aramis 2M, by correlating sample dimensions before and after polymerization. The greatest deformations of up to 6 % with the average of 3.5 % were observed along the periphery of the samples in contrast to substantially lower deformations of about 1-1.5% in the central parts. Polymerization of dental composites yields heterogeneous deformation with variations in shrinkage values. The 3D optical system is a promising tool enabling qualitative and quantitative mapping of local deformation fields in dental composites.

AB  - Introduction. Canal irrigation is an important segment of endodontic treatment. The aim of this study was to assess the efficacy of 0.5% NaOCl solutions of different pH values on smear layer removal. Material and Methods. Thirty-two freshly extracted single rooted teeth with gangrenous pulp were used in the study. The samples were divided into four groups of eight teeth in each. Four solutions of 0.5% NaOCl having pH values 5, 7, 9 and 12 respectively, were used during chemomechanical instrumentation with hand instruments and using step back technique. SEM analysis was done to assess the quality of smear layer removal in apical, middle and coronal part of root canal. Presence and quantity of smear layer and detritus was quantified using the scale from 1 to 5. Results. SEM analysis results showed similar results for 0.5% NaOCl solutions of different pH values in root canal cleaning with no statistically significant differences. Conclusion. The most effective cleaning root canal was achieved with 0.5% NaOCl solution of pH 5.

AB  - Nowadays, sodium hypochlorite is the irrigant of choice in endodontic therapy because of its characteristics. In the dental practice, the most often used are commercial solutions of different concentrations. The aim of this study was to investigate the possibility of using some home bleach solutions as possible agents for root canal irrigation. Sneznik (Panonija AD Pancevo) and Brekin (Briskol Chemical Industry Vrsac) were used as the materials in this study. The presence and concentration of hard metals were detected using atomic absorption spectrophotometry (AAS). The results have shown that the concentration of hard metals in the tested solutions, Sneznik and Berekin, was below maximum allowed concentrations for tap water. Tested solutions could be recommended for root canal irrigation but only after hard metal concentration is checked.

AB  - Introduction: Postoperative sensitivity is a common problem in patients after placement of resin-based composite (RBC) restorations. Aim: The of this study was to evaluate clinical efficacy of oxalate desensitizer BisBlock in the prevention of postoperative sensitivity after placement of RBC restorations. Materials and Methods: This clinical study was conducted at Belgrade University School of Dentistry Department of Restorative Dentistry and Endodontics. The study comprised 31 patients, both sexes, aged 18 - 32. In each patient, two class II cavities were prepared in premolars (62 cavities) and restored with RBCs. One restored tooth in each patient was treated with BisBlock (experimental group) while another served as control. In the restorative procedure, Single Bond (3M ESPE) was used as the adhesive and teeth were restored with Valux Plus (3M ESPE) RBC. Sensitivity evaluation was performed at day 1, day 4 and day 7 after restoration and comprised sensitivity on thermal and osmotic stimuli as well as sensitivity during mastication. Results: The obtained results revealed statistically significant decrease of postoperative sensitivity in experimental (3.23%) than control group (16.14%). .
AB  - Uvod: Postoperativna osetljivost je čest problem kod pacijenata nakon postavljanja kompozitnih ispuna na zubima. Cilj ovog istraživanja je bio da se proveri klinička efikasnost oksalatnog desenzibilizatora BisBlock u prevenciji postoperativne osetljivosti posle postavljanja kompozitnih ispuna na bočnim zubima. Materijal i metod: Kliničko istraživanje je sprovedeno na Klinici za Bolesti zuba Stomatološkog fakulteta Univerziteta u Beogradu. U istraživanje je uključen 31 pacijent, osoba oba pola, uzrasta od 18 do 32 godine. Kod svakog pacijenta su urađena dva kaviteta druge klase na premolarima (62 kaviteta) i restaurisani kompozitnim ispunima. Jedan restaurisani zub svakog ispitanika je tretiran BiSBlock-m (ekperimentalana grupa) dok je drugi poslužio kao kontrolna grupa. U restaurativnoj proceduri kao adhezivno sredstvo je korišćen Single Bond (3M ESPE) a zubi su restaurisani kompozitnim materijalom Valux plus(3M ESPE). Procena osetljivosti je vršena posle prvog, četvrtog i sedmog dana od restauracije, ispitivanjem osetljivosti na termičke i osmotske nadražaje i ispitivanjem osetljivosti na pritisak u toku mastikacije. Rezultati: Dobijeni rezultati su pokazali da je upotrebom desenzibilizatora BisBlock-a došlo do statisticki značajnog smanjenja pojave postoperativne osetljivosti kod eksperimentalne (3.23%.) u odnosu na kontrolnu grupu (16.14%). .

AB  - The therapy of non-caries cervical lesions is an important problem in restorative dentistry, for the ambiguous aetiology, clinical diagnoses and for the selection of restorative procedure. Aim: The aim of this work was to clinically check the efficiency of non-caries cervical lesions restoration depending on materials used for restorative fillings. Materials and methods: Clinical researches covered 62 teeth of different morphology group at the patients of both gender and of different age. The restoration of gingival lesions, with no previous preparation, was done with composite adhesive system SINGLE BOND/Valux Plus (3M) (30 teeth) and with campomer DYRACT AO (Dentsplay) (32 teeth). The fillings were estimated on the checkups which took place on 3,6 and12 months applying modified criteria according to Ridge and Cvar. Results: The acquired results showed that after 3 to 6 months there were no changes at none of examined parameters and all the fillings got maximal mark A. 12 months latter, in the two cases with composite filling, the marginal adaptation got the mark B (607%). The marginal adaptation at two teeth restored with compomers got the mark B (6.3%) Postoperative sensitiveness phenomenon, marginal discoloration and secondary caries weren’t registered in none of the cases after the observation period of 12 months. Conclusion: For the restoration of non-caries cervical lesions, composite materials with suitable adhesive system and the new generation of compomers could be used.
AB  - Terapija nekarijesnih cervikalnih lezija je značajan problem u restaurativnoj stomatologiji, zbog nejasne etiologije, kliničke dijagnoze ali i izbora restaurativne procedure. Cilj: Cilj ovog rada je bio da se klinički proveri efikasnost restauracija nekarijesnih cervikalnih lezija zuba u zavisnosti od korišćenih materijala za restaurativne ispune. Materijal i metod: Klinička ispitivanja su obuhvatila 62 zuba različitih morfoloških grupa kod pacijenata oba pola i različite starosti. Restauracija gingivalnih lezija, bez prethodne preparacije, urađena je kompozitnim adhezivnim sistemom SINGLE BOND/Valux Plus (3M) (30 zuba) i kompomerom DYRACT AP (Dentsplay) (32 zuba). Ispuni su procenjivani na kontrolnim pregledima posle 3, 6 i 12 meseci primenom modifikovanih kriterijuma po Ridge-u i Cvar-u. Rezultati: Dobijeni rezultati su pokazali da posle 3 i 6 meseci nije bilo promena na ispunima ni kod jednog ispitivanog parametra i svi ispuni su ocenjeni maksimalnom ocenom A. Posle 12 meseci, u dva slučaja ispunjenih kompozitima, ivična adaptacija je ocenjena ocenom B (6,7%). Ivična adaptacija je i u dva zuba restaurisanih kompomerima ocenjena ocenom B (6,3%). Pojava postoperativne osetljivosti, ivične diskoloracije i sekundarnog karijesa nije registovana ni u jednom slučaju posle observacionog perioda od 12 meseci. Zaključak: Za restauraciju nekarijesnih cervikalnih lezija mogu se koristiti kompozitni materijali sa odgovarajućim adhezivnim sistemima i novije generacije kompomera.
