Abstract

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=< 0>
Conclusion: Reinforcement with titanium posts can significantly improve the fracture strength of reattached teeth and results in a favourable fracture mode.

Keywords: Fiber posts, Reattachment, Super bond C& B, Titanium posts.
