Comparison of Fracture Resistance of Different Reattachment Techniues and Adhesive Materials on Incisal Tooth Fragment Reattachment
Purpose: This is an in vitro study to compare fracture resistance of different reattachment techniques and adhesive materials on incisal tooth fragment reattachment. Methodology: 100 sound human maxillary central incisors were selected .10 were maintained as a control group. Remaining 90 were divided randomly into 3 groups (n=30) based upon the materials used for reattachment and further divided into 3 subgroups (n=10) on the basis of different reattachment techniques. The materials used are dual cure resin cement, flowable composite, nano hybrid composite and three different reattachment techniques used were simple reattachment , overcontour and internal dentinal groove. Data was analyzed with ANOVA (One-Way) test and Post-Hoc Bonferroni test. Results: The control group had a significantly higher fracture resistance (p= 0.001); the highest fracture resistance values were obtained by Dual cure resin cement followed by Nano hybrid composite and minimum in Flowable composite .When compared between three different reattachment techniques internal dentinal groove showed the maximum fracture resistance followed by over contour technique and minimum showed the simple reattachment technique. Conclusion: Although, none of the tested materials provided fracture resistance similar to that found with the intact maxillary central incisors, utilizing the dual cure resin cement improved the fracture resistance of the reattached fragment than other materials.
