Abstract

ackground:  The aim of this study is to evaluate the fracture resistance of teeth when flared root canals are reinforced using bulkfill composite and fiber post.  Materials and method: A total of 30 freshly extracted human maxillary central incisors were collected. The teeth were divided into 3 groups of 10 specimens each. All specimens were simulated to flared root canals by instrumenting using peeso reamers Group 1 (control group), Group 2 (experimental group; Direct anatomic post), Group 3 (experimental group; Flowable bulk fill resin). All teeth were subjected to fracture testing using a universal testing machine and data recorded in newtons. Statistical analysis: Statistical data is analyzed using one way ANOVA test and Tukey post hoc test for intergroup comparisons exhibiting the p-value of P< 0.05, which was significant. Result: Group 2 & 3 had a statistically significant effect on the fracture strength of flared roots (p<0.05) When compared with group 1. Intergroup comparison shows no statistically difference between group 2 & 3 (p>0.05). Highest fracture resistance was observed in group 2 Conclusion: Both direct anatomic and flowable bulk fill technique increased the fracture resistance of teeth with no statistical significance; however, direct anatomic post group showed the highest value of fracture resistance.
