Title

A COMPARISON OF APICALLY EXTRUDED DEBRIS BETWEEN CONVENTIONAL AND 2 ROTARY INSTRUMENTATION TECHNIQUES ACCORDING TO THE NUMBER OF APPLICATIONS (AN IN VITRO STUDY)

Pages

  7-13

Abstract

 Background and Aim: Various kinds of hand or rotary techniques are used for mechanical preparation of the root canal. The aim of this study was to assess the influence of the number of applications of conventional and two rotary instrumentation techniques (Profile, Flex Master) on the apical extrusion of debris.Materials and Methods: In this study, 73 single rooted mandibular premolars with curvatures between 0 to 10 degrees were divided into three groups. Groups H, P and F were prepared by the hand step-back, Profile and Flex Master techniques, respectively. Preweighed vials (0.0001 precision) containing distilled water was used to collect debris. After CANAL PREPARATION, the vials were completely dried and weighed again. The weight of the debris extruded from the apical foramen was calculated by assessing the difference between the weights of the vials, before and after CANAL PREPARATION. One-way ANOVA was used to compare the mean weight differences of the debris between the numbers of applications of the three different techniques.Results: The weight of the debris varied significantly according to the number of times the Profile technique was applied (n=6), i.e. the quantity of debris decreased with increased application. A statistically significant difference was not observed between the numbers of applications using the other studied techniques.Conclusion: New Profile instruments induce more extrusion of debris from the apical foramen as compared to previously used instruments.
