Abstract

Purpose

The purpose of the present study was to examine how the various resection methods effect the root fracture resistance of the endodontic surgery.

Methods

A test for the fracture resistance was performed using forty extracted human teeth. The root canals were prepared with rotary instruments and obturated with cold lateral compaction of gutta percha + root canal sealer. Apical 3-mm portions of the roots were resected. While all roots were divided into three experimental groups, 10 roots were used for the control group. Retrograde cavities were prepared using slow-speed tungsten carbide round burs, ultrasonic retrotips, and Er,Cr:YSGG laser. All cavities were restored with MTA. Roots were embedded in acrylic resin-filled cylindrical molds until 2 mm beneath the cementoenamel junction. The force with a speed of 1 mm/min was applied vertically along the long axis of the tooth. Then, the highest fracture resistance of each tooth was measured in Newtons. The recorded data were statistically analyzed with one-way ANOVA and post hoc Tukey tests.

Results

According to the results, there was no statistically significant difference among the groups (p > 0.05).

Conclusion

Root-end preparation methods had no effect on the fracture resistance of teeth.
