Effect of mode of rotation on apical extrusion of debris with four different single‐file endodontic instrumentation systems: Systematic review and meta‐analysis

摘要

Abstract This systematic review and meta‐analysis evaluated whether single‐file endodontic instrumentation systems with the reciprocating type of motion are responsible for more debris extrusion than single‐file endodontic instrumentation systems with the full rotational type of motion. Electronic and manual searches were performed following the recommendations of Preferred Reporting Items for Systematic Reviews and Meta‐Analysis – PRISMA. We included studies comparing rotary (Neoniti and/ OneShape) versus reciprocating (WaveOne and/ Reciproc) systems. We evaluated the quality of studies and performed statistical analysis using R‐Project software. Eight studies of high quality were included to perform the meta‐analysis. Subgroup analysis was also done. The overall risk of bias was too low. In conclusion, single‐file reciprocating systems tend to generate more extrusion of debris than single‐file rotary systems.
