Apical Displacement Produced by Rotary Nickel-titanium Instruments and Stainless Steel Files Deslocamento Apical Produzido Por Instrumentos De Níquel- Titânio Acionados a Motor E Limas De Aço Inoxidável
he aim of this study was to evaluate the apical displacement produced by different rotary nickel-titanium instruments, testing the hypothesis that rotary systems with nickel-titanium instruments produce lower mean values of apical displacement than stainless steel hand instruments. A total of 100 maxillary permanent first molars were selected for the study. The mesiobuccal roots were sectioned ...

متن کاملA comparison of stainless steel hand and rotary nickel-titanium instrumentation using a silicone impression technique.
BACKGROUND Root canal preparation using rotary nickel-titanium instruments has been reported to be superior to hand instrumentation in terms of root canal shape, centring and frequency of procedural errors. The purpose of this study was to evaluate canal preparations using a sequential silicone impression technique to assess root canal morphology. METHODS Pre-operative canal impressions were ...
متن کاملThe accuracy of the Root ZX electronic apex locator using stainless-steel and nickel-titanium files.
Numerous apex locator studies have been performed. Generally, they use only stainless-steel hand files for testing purposes. Today many clinicians use both stainless-steel and nickel-titanium files during the treatment of a case. Given the widespread use of nickel-titanium files, a comparison of the accuracy in determining length with an apex locator using stainless-steel and nickel-titanium fi...
متن کاملRe: A micro-computed tomographic evaluation of apical root canal preparation using three instrumentation techniques.
AIM To investigate the morphological changes in the apical third of the root canal after preparation with three techniques. METHODOLOGY Forty molar teeth were scanned using micro-computed tomography before and after instrumentation with: Group 1 - stainless steel K-files using the balanced force technique; Group 2 - stainless steel K-files (balanced force) and then refining the apical prepara...
