Background: Endodontic treatment results in a reduction of fracture resistance of teeth. It is generally accepted that the strength of an endodontically treated tooth is directly related to the amount of remaining sound tooth structure. The present study was conducted to compare the fracture resistance of root canals obturated with different obturating systems. Material and methods: The present study was conducted to compare the fracture resistance of root canals obturated with different obturating systems in 80 freshly extracted single-rooted anterior teeth. All debris and remaining tissues were removed from the teeth, and the teeth were disinfected with 5% sodium hypochlorite solution and then kept in normal saline solution. All specimen were randomly divided into two experimental groups and two control groups. All prepared teeth were vertically set in self-cure acrylic resin blocks Fracture resistance was evaluated in a Universal Testing Machine. The force necessary to fracture each tooth was recorded in Newtons. Statistical analysis was done using software SPSS (version 20.0) The post hoc Tukey-HSD test were used for analysis of data. P-value of less than 0.05 was considered statistically significant. Results: The result showed that the mean difference of fracture resistance in Group II (+ve control) was statistically significantly lower than all other groups. There was no significant difference between Group II and Group IV. On the basis of the above assessment, the following order of fracture resistance was observed in the different groups: Group I > Group III > Group IV>Group II. Conclusion: Our study concluded that the fracture resistance was maximum in group I that were Negative control group. Teeth obturated using cold lateral compaction technique showed better fracture resistance than teeth obturated using injection-molded thermoplasticized technique with C-fill system.
Keywords: Fracture resistance, C-fill, cold compaction.
