Introduction: Reattachment of fractured tooth fragment is the contemporary minimal intervention concept. Aim: To compare the fracture resistance of three reattachment techniques in fractured endodontically treated incisors. Materials and Methods: Eighty maxillary central incisors were divided into four groups (n=20 each), where group A samples served as control. Remaining (n=60) crowns were sectioned experimentally, and after root canal treatment, in group B reattachment was done by placing palatal grooves and overcontouring. In group C, teeth were reattached by placing glass fiber posts and in group D, titanium posts were used. After thermocycling, fracture resistance evaluation was done by using universal testing machine and mode of failure was analysed under stereomicroscope. Statistical Analysis: The force required to fracture the tooth recorded in newtons was subjected to statistical analysis using one-way ANOVA and Tukey’s multiple post-hoc test with a level of significance ?=0.05. Results: Reattachment with titanium post reinforcement has shown higher fracture resistance, whereas palatal grooves with over-contouring has exhibited lowest resistance to fracture (p= Conclusion: Reinforcement with titanium posts can significantly improve the fracture strength of reattached teeth and results in a favourable fracture mode.

The knowledge of variations in root canal morphology is essential for a successful endodontic outcome. Contralateral mandibular molar with six root canals is a rare entity. Root canal treatment of mandibular molars with aberrant canal configuration can be diagnostically and technically challenging. While dealing with variant mandibular molars, mishaps may happen. This case report describes variations in contralateral mandibular molars and also an endodontic mishap while managing them.

Background To facilitate the easier placement of direct resin composite in deeper cavities, bulk fill composites have been introduced. The Mechanical stability of fillings in stress bearing areas restored with bulk-fill resin composites is still open to question, since long term clinical studies are not available so far. Thus, the objective of the study was to evaluate and compare the microtensile bond strength of three bulk-fill restorative composites with a nanohybrid composite. Material and Methods Class I cavities were prepared on sixty extracted mandibular molars. Teeth were divided into 4 groups (n= 15 each) and in group I, the prepared cavities were restored with nanohybrid (Filtek Z250 XT) restorative composite in an incremental manner. In group II, III and IV, the bulk-fill composites (Filtek, Tetric EvoCeram, X-tra fil bulk-fill restoratives) were placed as a 4 mm single increment and light cured. The restored teeth were subjected to thermocycling and bond strength testing was done using instron testing machine. The mode of failure was assessed by scanning electron microscope (SEM). The bond strength values obtained in megapascals (MPa) were subjected to statistical analysis, using SPSS/PC version 20 software.One-way ANOVA was used for groupwise comparison of the bond strength. Tukey’s Post Hoc test was used for pairwise comparisons among the groups. Results The highest mean bond strength was achieved with Filtek bulk-fill restorative showing statistically significant difference with Tetric EvoCeram bulk-fill (p< 0.003) and X-tra fil bulk-fill (p
