Comparative in Vitrostudy of Root Roughness after Instrumentation with Ultrasonic and Diamond Tip Sonic Scaler
OBJECTIVE The purpose of this study was to evaluate the root surface roughness after instrumentation with hand curette and diamond-coated sonic and universal ultrasonic tips. MATERIALS AND METHODS Forty root surfaces of human teeth were randomly assigned to four treatment groups: control group (without instrumentation), curette instrumentation, ultrasonic instrumentation with universal tip an...
متن کاملUltramorphology of the root surface subsequent to hand-ultrasonic simultaneous instrumentation during non-surgical periodontal treatments. An in vitro study
OBJECTIVE The purpose of this study was to investigate the ultramorphology of the root surfaces induced by mechanical instrumentation performed using conventional curettes or piezoelectric scalers when used single-handedly or with a combined technique. MATERIAL AND METHODS Thirty single-rooted teeth were selected and divided into 3 groups: Group A, instrumentation with curettes; Group B instr...
متن کاملRoot surface defect produced by hand instruments and ultrasonic scaler with different power settings: an in vitro study.
The aim of this study was to evaluate the root surface defect produced by hand curettes and ultrasonic tips with different power settings. Forty root surfaces were divided into 4 groups according the treatment: Gracey curettes, ultrasonic scaler at 10% power, ultrasonic scaler at 50% power and ultrasonic scaler at 100% power. Each specimen was instrumented with 15 strokes and the and divided in...
متن کاملScanning electron microscopic evaluation of root-end preparations.
The use of an ultrasonic apical preparation technique has been advocated recently. Root-end preparations in 30 extracted single-canaled human teeth were evaluated, comparing those prepared with ultrasonic instrumentation alone, or in combination with rotary bur preparation, to those prepared with rotary instrumentation alone. Specimens were evaluated for the presence of debris, smear layer, and...
متن کاملComparison of the cleaning efficacy of passive sonic activation and passive ultrasonic activation after hand instrumentation in molar root canals.
The purpose of this study was to compare the cleaning efficacy of passive ultrasonic activation with that of passive sonic activation after hand instrumentation. Sixty curved molar canals were hand-instrumented to size 35 and divided into three groups. Group 1 received no further treatment. Group 2 received 3 min of passive sonic activation. Group 3 received 3 min of passive ultrasonic activati...
متن کاملEffectiveness of halothane used with ultrasonic or hand instrumentation to remove gutta-percha from the root canal.
This study compared halothane and chloroform used with hand or ultrasonic instrumentation to remove gutta-percha and sealer from root canals. Apically extruded debris, residual debris, time for filling removal, and amount of solvent used were determined. The differences in extruded apical debris and radiographically visible residual debris were not significant (p greater than 0.05). Ultrasonic ...
