ProTaper rotary root canal preparation: effects of canal anatomy on final shape analysed by micro CT.
AIM To evaluate the relative performance of ProTaper nickel-titanium (Ni-Ti) instruments shaping root canals of varying preoperative canal geometry. METHODOLOGY Extracted human maxillary molars were scanned, before and after shaping with ProTaper, employing micro computed tomography (muCT) at a resolution of 36 mum. Canals were three-dimensionally reconstructed and evaluated for volume, surfa...
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 کاملEvaluation of Root Canal Preparation Using Rotary System and Hand Instruments Assessed by Micro-Computed Tomography
BACKGROUND Complete mechanical preparation of the root canal system is rarely achieved. Therefore, the purpose of this study was to evaluate and compare the root canal shaping efficacy of ProTaper rotary files and standard stainless steel K-files using micro-computed tomography. MATERIAL AND METHODS Sixty extracted upper second premolars were selected and divided into 2 groups of 30 teeth eac...
متن کاملEffects of root canal preparation on apical geometry assessed by micro-computed tomography.
INTRODUCTION Previous micro-computed tomography analyses of root canal preparation provided data that were usually averaged over canal length. The aim of this study was to compare preparation effects on apical root canal geometry. METHODS Sixty extracted maxillary molars (180 canals) used in prior studies were reevaluated for analyses of the apical 4 mm. Teeth were scanned by using micro-comp...
متن کاملEffects of preparation techniques on root canal shaping assessed by micro-computed tomography
BACKGROUND Root canal shaping without any procedural error is of the utmost preference. Therefore, the purpose of this study was to use micro-computed tomography to evaluate and compare the root canal shaping efficacy of ProTaper rotary files and standard stainless steel K-files. MATERIAL AND METHODS Sixty extracted upper second premolars were selected and were divided into 2 groups of 30. Be...
