Aim: The aim of this study is to compare the bond strength of fractured teeth reattached using four different techniques, i.e., simple reattachment, overcontour, internal dentinal groove, and enamel bevelling using nanohybrid resin composite. Materials and Methods: A total of eighty extracted permanent maxillary central incisor teeth was used in this study. Sample was uniformly divided into four groups, i.e., (n = 20). Group I: Fracture teeth reattached with a simple technique. Group II: Fracture teeth reattached with overcontouring technique. Group III: Fracture teeth reattached with the internal dentinal groove technique. Group IV: Fracture teeth reattached with enamel bevelling technique. After the fracture teeth reattachment, the specimens were mounted on a custom-made fixture and were kept in saline till the specimens were subjected to the bond strength testing. The universal testing machine was used for the determination of bond strength. One-way ANOVA test was used to analyze the data and post hoc test was used for comparing (testing) three or more means (groups or variables) for statistical significance. SPSS 17.0 version was the software used in this analysis, and the level of significance was set at P = 0.002. Results: Highest bond strength was seen with Group II (reattached with overcontour technique) (9.04 ± 4.94) followed by Group III (inter-dentinal groove technique) group (8.04 ± 2.48), then Group IV (enamel bevelling technique) (5.87 ± 3.77), and least bond strength was with Group I (simple reattachment) (5.17 ± 1.59). Conclusion: Overcontour fracture reattachment technique displayed significantly higher bond strength as compared to simple reattachment, internal dentinal groove, and enamel bevelling techniques.
