超声洁治及橡皮杯抛光对牙釉质表面的影响
Effect of the number of ultrasonic scaler scraping and rubber polishing on the surface roughness of teeth in vitro
摘要
Abstract
Objective: To investigate the effects of the frequency of the use of the ultrasonic scaler scraping and Rubbet polishing on the surface roughness of teeth in vitro. Method: The surface of 80 bicuspid teeth which were treated with ultrasonic scaler by different frequencies was observed with surface roughness measuring instrument. Then the measurements as the surface roughness (Ra) could be obtained. We observed the values of Ra and analyzed how the different polishing time with rubber would influence these surfaces. Result:The surface of teeth treated with ultrasonic scaler became rougher (P ＜0.05). The surface roughness of the enamel increased as the frequency of the use of the supersonic cleans was increased too.But after being polished with rubber polishing cup, it could become smoother (P ＜0.05). Although the Polishes lasted for 2～4 s,the surface roughness had non-significant differences compared with those natural teeth (P ＞0.05). Conclusion: By the clinical disposal with ultrasonic supragingival scaling, we could increase the surface roughness of the enamel, after being polished for 2～4 s,the surface roughness may drop as similar as these natural ones.关键词
