An in vitro Comparison of Apically Extruded Debris with the use of Full Sequence M-two and Heroshaper Ni-Ti File systems
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 2
Abstract
Introduction: During rootcanal preparation, irrigants, dentin chips, pulp tissues may extrude into periapical tissues and may cause postoperative pain. The main objective of the present study was to compare the amount of apically extruded debris using M-two and HERO Shaper Nickel titanium instruments. Material and Methods: Forty freshly extracted human permanent single rooted straight teeth with single canal were divided into two groups each allotted with 20 teeth. Rotary Mtwo system used for instrumentation in one group and Hero-shaper for other group and each group was divided into two sub groups of sample size 10 each. Regardless of instrumentation technique, each group was irrigated with 1ml of distilled water. Debris extruded were collected using eppendorf tubes. Results: All rotary instruments used in this study caused apical extrusion of debris. A statistically significant difference was observed between two groups. Conclusion: Followed by instrumentation with different rotary file systems, HERO shapers with glide path created mechanically showed a less apical debris extrusion compared to Mtwo
