ProTaper rotary instrument fracture during root canal preparation: a comparison between rotary and hybrid techniques.
AIMS This study aimed to compare the frequency of ProTaper rotary instrument fracture with rotary (conventional) and hybrid (rotary and hand files) canal preparation techniques. Secondary objectives were to determine whether there was an association of ProTaper file fracture with the canal curvature and to compare the mean time required for canal preparation in the two techniques. METHODS An ...
متن کاملInfluence of instrument size on root canal debridement.
Files of Greater Taper (GT) are rotary nickel-titanium files of three tapers (0.06, 0.08, 0.10) with file tips of sizes 20, 30, and 40. The purpose of this study was to compare in an in situ model the efficacy of root canal debridement in the apical 3 mm when instrumenting to a GT size 20 or a GT size 40 at working length. Twenty matched human cadaver teeth with 32 canals were decoronated at th...
متن کاملInfluence of Taper of Root Canal Shape on the Intracanal Bacterial Reduction
OBJECTIVES Taper is a factor that determines final root canal dimensions and consequently, the space available for the cleaning action of irrigants. Therefore, the aim of this study was to investigate the influence of taper on intracanal bacterial reduction. METHODS Sterilized root canals of 25 mandibular incisors were inoculated with E. faecalis and then divided into two experimental groups ...
متن کاملRoot canal preparation with a novel nickel-titanium instrument evaluated with micro-computed tomography: canal surface preparation over time.
INTRODUCTION The aim of this part of an ongoing study was to describe the dentin removal ability of a novel nickel-titanium instrument, the self-adjusting file (SAF), by using micro-computed tomography. METHODS Twenty maxillary incisors were scanned preoperatively at 20-microm resolution and postoperatively after up to 6 minutes of preparation with an SAF with 1.5-mm or 2-mm diameter. SAFs we...
متن کاملReduction in intracanal bacteria during root canal preparation with and without apical enlargement.
AIM To compare in vitro intracanal bacterial reduction using nickel-titanium rotary instruments with and without apical enlargement. METHODOLOGY Thirty-eight palatal roots of maxillary molar teeth, with mature apices were subdivided according to lengths and then randomly assigned to two experimental and one control groups. The roots were sterilized and then reinfected with Enterococcus faecal...
