半导体激光在牙齿美白术中的应用

The clinical study by lasers-assisted in tooth bleaching

目的:了解半导体激光在牙齿美白术中的应用。方法:随机选择78例患者,女性患者比男性多,约4:1,平均年龄33岁。35%H2O2作为美白剂,美白过程中以半导体激光进行牙齿美白催化。结果:经过4个循环近1h的牙齿激光美白,牙齿在色阶上有显著性差异,美白过程中,患者有不同程度酸痛感,24h后不适感消失。结论:半导体激光美白牙齿效果显著,对周围组织刺激性小,临床易于推广应用。

Objective To understand the effect of the clinical trail study by diode Lasers-assisted in tooth bleaching. Methods eighty patients at random （Average age was 33 years） Who had done in office diode laser-assisted tooth bleaching with 35% H202,data were collected. Results After four rounds diode-assisted tooth bleaching, there are significant changes with the teeth shade. During the tooth bleaching procedure, patients felt slightly tooth sensitivity.After 24 hour,there is no patient has any tooth sensitive. Conclusion the effect of tooth Laser-assisted bleaching is satisfied, The patient has less tooth sensitive for treatment,it could be used in clinical study.
