Abstract

Aim: The present study aimed to compare and evaluate debris and irrigant extrusion from curved root canals using different rotary systems.

Materials and methods: 30 single-rooted mandibular canines were used in this study. The crown was decoronated, working length and initial apical diameter were established. A 1.5% agar gel model was used in this study. Samples were assigned randomly into 3 groups (n = 10 teeth per group). Protaper Next, OneShape, and Hanudent files were used according to the manufacturers' instructions for canal instrumentation. Apically extruded debris and irrigant was were computed by deducting the initial weight of the test apparatus without a tooth from its weight after the biomechanical preparation. Comparative analysis of the amount of apically extruded debris and irrigant for each of the instruments and the experimental models was performed.

Results: The statistically significant difference was found between the three experimental groups. (P < .05). Among all the groups least extrusion was observed in the Protaper Next group when used in combination with conventional irrigation.

Conclusion: All the instruments produced apically extruded debris and irrigant, but the maximum was seen with OneShape among the experimental groups.

Keywords: Apically extruded debris and irrigant; Hanudent; OneShape; ProtaperNext.
