Apical extrusion of debris by manual and mechanical instrumentation.
The aim of the present study was to assess the presence of apically extruded debris and evaluate the influence of canal curvature on the amount of debris produced by manual and mechanical techniques. Forty single-rooted mature teeth with 15 to 30 degree of root canal curvature were selected. The presence of only one foramen was confirmed using a magnifying lens. A size 15 K-file was placed up t...
متن کاملQuantitative evaluation of apical extrusion of debris and irrigants using four rotary instrumentation systems: an in vitro study.
CLINICAL SIGNIFICANCE The apical extrusion of infected debris may have the potential to disrupt the balance between microbial aggression and host defense, resulting in incidents of acute inflammation. During preparation, irrigants and debris, such as bacteria, dentin filings and necrotic tissue may be extruded into the periradicular region leading to periapical inflammation and postoperative fl...

متن کاملthe influence of instrument application frequency on apical extrusion of debris in three instrumentation techniques
introduction various kinds of hand-held or rotary techniques are used for mechanical preparation of the canal. the purpose of this study was to assess the influence of the number of applications on apical extrusion of debris in conventional and two rotary instrumentation techniques (profile, flex master). methods and materials in this in vitro study, 75 extracted single-rooted human mandibular ...
متن کاملApical Extrusion of Intracanal Debris Using Two Engine Driven and Step-Back Instrumentation Techniques: An In-Vitro Study
OBJECTIVES The purpose of this study was to compare in-vitro the amount of debris extruded apically from extracted teeth, using K3, Protaper rotary instruments and manual step-back technique. METHODS Forty five human single-rooted mandibular premolar teeth were randomly divided into 3 groups. The teeth in 3 groups were instrumented until reaching the working length with K3, Protaper rotary in...
