Root Canal Preparation of Maxillary Molars With the Self-adjusting File: A Micro-computed Tomography Study

Root canal preparation of maxillary molars with the self-adjusting file: a micro-computed tomography study.

INTRODUCTION The aim of this study was to describe the canal shaping properties of a novel nickel-titanium instrument, the self-adjusting file (SAF), in maxillary molars. METHODS Twenty maxillary molars were scanned by using micro-computed tomography at 20-μm resolution. Canals were shaped with the SAF, which was operated with continuous irrigation in a handpiece that provided an in-and-out v...

Flat-oval root canal preparation with self-adjusting file instrument: a micro-computed tomography study.

INTRODUCTION The aim of this study was to evaluate the root canal preparation in flat-oval canals treated with either rotary or self-adjusting file (SAF) by using micro-tomography analysis. METHODS Forty mandibular incisors were scanned before and after root canal instrumentation with rotary instruments (n = 20) or SAF (n = 20). Changes in canal volume, surface area, and cross-sectional geome...

Micro-computed tomography evaluation of the preparation of long oval root canals in mandibular molars with the self-adjusting file.

INTRODUCTION The aim of this study was to assess the shaping potential of a novel nickel-titanium instrument, the self-adjusting file (SAF), in long oval root canals in distal roots in mandibular molars. METHODS Twenty mandibular molars with long oval distal root canals were selected and scanned preoperatively and postoperatively by using micro-computed tomography at an original resolution of...
