Do Continuous Rotating Endodontic Instruments Extrude Fewer Apical Debris Than Reciprocating Instruments in Non-Surgical Endodontic Retreatments? A Systematic Review

Applied Sciences
Background: All endodontic treatment techniques are associated with the extrusion of debris into periradicular tissues through the apex. The extrusion of apical debris can lead to delayed healing or even therapy failure.

Apical extrusion of debris when using OneCurve, ProTaper Next and TruNatomy in curved canals

, 2023
Background. The extrusion of apical debris is related to various factors, and may be affected by varia-tions in technique or instrumentation system. Although the extrusion cannot be completely prevented, it is crucial to minimize the amount of extruded ...

Microtubule disassembly by caspases is an important rate-limiting step of cell extrusion

, 2022
The expulsion of dying epithelial cells requires well-orchestrated remodelling steps to maintain tissue sealing. This process, named cell extrusion, has been mostly analysed through the study of actomyosin regulation.

Comparison of apical debris extrusion using a conventional and two rotary techniques.

Iranian endodontic journal, 2010
Preparation techniques and instruments produce and push debris out of canals. This can induce inflammation within the periapical area. Therefore, instrumentation that causes less extrusion of debris is more desirable. The purpose of this in vitro study was to evaluate the quantity of debris extruded from the apical foramen during root canal preparation
