Comparative in vitro evaluation of the amount of apically extruded debris using different root canal instrumentation

Abstract

Background: To compare and evaluate the amount of apically extruded debris using root canal instrumentation. Materials and methods: A total of 15 mandibular first premolars were enrolled. They were divided into 3 groups (n = 5 teeth/group). The root canals were instrumented according to the manufacturers’ instructions using the Reciprocating single-file system Wave One™ and full-sequence rotary Hyflex CM™ and ProTaper™ instruments. The p- value less than 0.05 was considered significant. Results: The mean apically extruded weight of debris in Wave One (0.0075 g) was more when compared with the Hyflex (0.0020 g). Wave One™ and Pro Taper™ (0.0070 g) was significantly more when compared to Hyflex™ (p<0.05). Conclusion: The WaveOne™ and ProTaper™ rotary instruments produced significantly more debris compared with Hyflex CM™ rotary instruments (p<0.05).
