Root Canal Surface Strain and Canal Center Transportation Induced by 3 Different Nickel-Titanium Rotary Instrument Systems.
INTRODUCTION Root canal anatomy and canal preparation instruments affect the outcome of endodontic treatment. The purpose of this study was to determine the root surface strain (SS) generated and the extent of canal center transportation during canal shaping using 3 different nickel-titanium instruments. METHODS Simulated root canals in resin blocks (n = 10 per group) were prepared using adap...
متن کاملRemedying and preventing endodontic rotary nickel-titanium (NiTi) file breakage.
Of all the procedural problems that can occur when practicing dentistry, endodontic file breakage is one dilemma that not only can lead to extreme stress for the clinician, but can cause great anxiety for the patient as well. Separated rotary nickel-titanium (NiTi) files can also pose an increased risk of post-endodontic complications. Understanding why and how endodontic file breakage occurs, ...
متن کاملThe ability of different nickel-titanium rotary instruments to induce dentinal damage during canal preparation.
The purpose of this study was to compare the incidence of dentinal defects (fractures and craze lines) after canal preparation with different nickel-titanium rotary files. Two hundred sixty mandibular premolars were selected. Forty teeth were left unprepared (n = 40). The other teeth were prepared either with manual Flexofiles (n = 20) or with different rotary files systems: ProTaper (Dentsply-...
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 کاملThe effects of different nickel-titanium instruments on dentinal microcrack formations during root canal preparation
OBJECTIVE The aim of the present study was to investigate the incidence of dentinal microcracks caused by different preparation techniques. MATERIALS AND METHODS 120 extracted human mandibular incisor teeth were divided into five experimental groups and one control group (n = 20): Group 1: Hand preparation with balanced force technique up to #25 K-file. Group 2: Preparation with only ProTaper...
