Purpose Restorative materials and techniques have improved the clinical success of a variety of restorative procedures. Despite these new improvements, microleakage remains one of the leading causes of restoration failure and may lead to postoperative sensitivity, enamel microcracks, marginal staining, discoloration, recurrent caries, and deformation of teeth. This study evaluated microleakages of five recent resin composites in class V cavities. Materials and Methods Standardized class V cavities were prepared on the labial surfaces of one hundred extracted intact and noncarious human permanent premolar teeth. The cavities were divided into five groups (n=20) according to the resin composite material. Groups: A1, A2, A3, A4 and A5 were restored with Omnichroma, Spectrum, Mosaic, Tetric N-Ceram and Harmonize, respectively. The teeth were stained with methylene blue and then sectioned, and the extent of dye penetration was examined under a stereomicroscope and scanning electron microscope (SEM) to evaluate microleakage. One-way ANOVA test was used to statistically analyze the data. Statistical Package for Social Sciences Computer Software (SPSS) version 15.0 was used. Results Dye penetration was observed at the tooth-restoration interface in all the studied samples, with varying degrees of penetration. At the cervical margins of the cavities, no statistically significant difference in the microleakage scores was observed (P=0.16). At the cavity floor, no statistically significant difference in microleakage scores was observed (P=0.74). Omnichroma resin composite had the highest microleakage results. Conclusion Nanohybrid resin composites showed less microleakage than other resin composites. Among all the groups, Omnichroma showed the highest microleakage at the cavity floor and at the cervical areas. Clinical Significance In light of our findings, nanohybrid resin composites appear to be capable of reducing microleakage, and the results reported herein must be verified by additional clinical trials.

“…The surfaces were polished with the aid of 600-grit sandpaper (ERIOS, Ipiranga, São Paulo, Brazil), by using a circular polisher (DP-10, Panambra, São Paulo, SP, Brazil), under copious irrigation. The specimens were evaluated by three double-blind examiners calibrated (interand intra-examiner) regarding to the degree of microleakage at tooth-restoration interface at the occlusal and cervical margins with the aid of a stereoscopic loupe (XTD 217, LabKlass, Buenos Aires, Argentina) at x20 magnification, through a 4-point score system (table 2), modified from Dalli et al, 2010 [13]. The results obtained were tabulated and submitted to the nonparametric statistical analysis through Kruskal-Wallis and Mann-Whitney tests for multiple comparisons with level of significance of 5%.…”

composite on the microleakage of class V cavities. Fifteen premolars were freshly extracted and randomly divided into three experimental groups, according to the adhesive system used, as follows: P-90: Filtek P-90 adhesive; SE PLUS: Adper SE Bond adhesive; and SBMP: Adper Scotchbond MultiPurpose adhesive. Class V cavities were constructed on the buccal and lingual surface of each premolar exhibiting enamel margin at the oclusal surface and dentine margin at the water sealed, immersed in 50% silver nitrate for 24 hours, followed by immersion in a radiographic developing solution for 2 hours. The samples were cut and the degree of dye penetration was assessed with the aid of stereoscopic loupe at = 31.13; and SBMP = 36.90. The results were submitted Kruskal-Wallis and Mann-Whitney tests, showing statistically the smallest scores of dye penetration.The association of different adhesive systems with the silorane-based resin compo-KEYWORDS

IntroductionMicroleakage is one of the important contributing factors in the failure of resin restorations. The aim of this study was to determine the effect of the location of the gingival margin (enamel, dentin, or cementum) on nanohybrid composite resin on the microleakage of Class II posterior restoration.MethodsThis was an in vitro study done at Al-Farabi College of Dentistry and Nursing in Jeddah (Saudi Arabia). Eighty-one previously extracted human molars were taken from clinics at Al-Farabi College and divided into three main groups (27 each) according to the location of the gingival margin. Group 1: the location of the gingival margin was in the enamel. Group 2: at the cemento-enamel junction. Group 3: in the cementum. Each main group was divided into three subgroups (9 each) according to storage time. Subgroup A: storage time was 24 hours. Subgroup B: storage time was one month. Subgroup C: storage time was three months. Class II cavity was prepared in one proximal surface for each molar following the general principles of cavity preparation. All samples were restored by nanohybridresin composite (TetricEvoCeram). The specimens were stored in distilled water at 37°C and a humidity of 100% in an incubator for one day, one month, and three months, respectively, according to the subgroups. After sealing, the samples were stained with 2.5% methylene blue dye. Each sample was examined microscopically by a stereomicroscope using a computerized image analyzing system. Statistical analysis was done by two-way ANOVA test comparing dye penetration mean values (μm).ResultsThe value of dye penetration increased remarkably from enamel, Cemento-enamel junction [CEJ] to cementum, and this was statistically significant (p < 0.001).ConclusionNone of the materials tested was able to completely eliminate marginal microleakage at different gingival margins. The least dye penetration was detected at the enamel gingival margin followed by CEJ and then cementum. The least microleakage was observed at the gingival margin located in the enamel.
