“…25 Another hypothesis is that the materials share similar properties and consistency. 26 Nanohybrid resin composites (Tetric N Ceram, Mosaic and Harmonize) showed the least microleakage. These results were consistent with those of Shah et al, who compared nanohybrid resin composites to microfilled resin composites.…”

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.

“…20 About 2% MB dye was selected for this study because of its low molecular size which allows for the detection of minutest leakage where even bacteria cannot penetrate and is a more sensitive indicator of leakage. 19,20,[22][23][24] The dye-penetration studies are popularly employed due to their low cost and simplicity of technique and do not necessitate sophisticated materials, but they give questionable results. In the present study, the fluidfiltration and dye extraction techniques allowed the scaling of four perforation repair materials and presented corresponding results.…”

Introduction:In endodontic practice, technical accidents are commonly encountered such as furcation perforation. For everlasting success, furcation perforations shall be corrected rapidly with an ideal perforation sealing material. For an ideal perforation sealing material, the desirable properties include an adequate seal, minimal microleakage, good biocompatibility, high pushout strength, stability in blood-contaminated areas, bactericidal, induction of mineralization, osteogenesis, and cementogenesis, radio-opacity and ease of clinical manipulation. Mineral trioxide aggregate (MTA) is the commonly used furcation repair material, but it presents sundry clinical shortfalls for instance prolonged setting time, difficulty in handling, and tooth discoloration. To remodel the attributions of MTA, new materials have been introduced which include Biodentine, calcium-enriched material (CEM) cement, and Cention N (CN). Biodentine is used as a dentin substitute because of its excellent sealing potential, high compressive strength, high pushout strength, less setting time, good biocompatibility, and biomineralization properties. Calcium-enriched material cement is a water-based tooth-colored material that yields a biological glue, is biocompatible, and ability to induce osteogenesis and cementogenesis. Cention N is an "alkasite" restorative material, like compomer or ormocer materials. It is radiopaque and releases ions such as fluoride, calcium, and hydroxyl. Objectives: To evaluate and equate the sealing capability and pushout strength of ProRoot MTA, CEM cement, CN, and Biodentine as furcation perforation repair materials. Materials and methods: A total of 60 extracted permanent mandibular molars were collected, and furcation perforations were made between the roots in a standardized manner. Based on kind of perforation repair material, samples were arbitrarily categorized into four discrete groups having 15 teeth each. In group I, samples were restored with ProRoot MTA. In group II, samples were restored with CEM Cement. In group III, samples were repaired with CN, and in group IV, samples were revived with Biodentine. After which, five samples from each group were selected for sealing ability testing using the dye extraction method by spectrophotometer, five samples from each group were selected for microleakage testing using the dye infiltration method followed by sectioning and evaluation of the sectioned samples by stereomicroscope, and five samples from each group were selected for Pushout strength evaluation by embedding them in acrylic using polyvinyl chloride (PVC) molds and subjecting them to universal testing machine. The data collected was statistically analyzed. Results: The mean spectrophotometric dye absorbance was significantly higher in CN followed by CEM cement and dye absorbance was least in ProRoot MTA and Biodentine. Infiltration loss was significantly higher among ProRoot MTA and Biodentine compared to CEM cement and CN. The mean pushout strength was significantly higher in Biodentine followed by ...

“…Some studies showed that BF composite has lower polymerization shrinkage and gap formation than conventional composites [26,27]. Other studies, however, showed comparable shrinkage for both material types [28,29]. Studies focusing on photoinitiator systems in both BF and conventional composites are very scarce.…”

Objective: The aim of this study was to assess the knowledge and utilization of Bulk-Fill (BF) resin composites among dental practitioners in Saudi Arabia. Materials and Methods: An online survey was distributed through Twitter, Instagram and WhatsApp applications among dentists in Saudi Arabia. A 31-item questionnaire covering personal data, general knowledge and utilization of BF composites was used. Responses were collected and analyzed for trends. A knowledge scale was developed based on answers with specific weight for each correct answer provided by the participants. A score of ≥ 50% was considered as a satisfactory knowledge level for participants. Statistical analysis was conducted using One-sample Z- and Chi-square tests followed by Bonferroni correction at 0.05 significance level. Results: The total number of participants of the survey was 183, of which 41.5% had some knowledge and utilized BF composites in their practice. Only 9.84% of the participants score ≥ 50% on the knowledge scale. A significantly low proportion recognized accurately the compositional difference between BF and conventional resin composite as well as the minimum irradiance values needed for proper polymerization of BF. There was no effect for gender or years of experience on the knowledge or utilization of BF materials (p-value = 0.172). Conclusion: The proportions of practitioners with adequate knowledge and utilization of BF materials were very low. Additional focus must be provided in order to expose graduating dentists to advances in resin composite formulations.
