摘    要:目的:评价显微超声去龋技术和传统涡轮机去龋技术的临床应用效果。方法:选取30颗龋坏深度相似的牙齿,随机分为实验组和对照组,分别使用显微超声技术和涡轮机技术去龋。比较两组去龋过程中患者对疼痛的敏感性,去龋后窝洞内牙本质碎屑的形成情况及去龋时间的差异。结果:实验组所有的患者感觉无痛或者轻度疼痛,对照组仅53.3%的患者感觉无痛或者轻度疼痛,经检验,两组患者去龋过程中疼痛感受具有显著性差异(P<0.05);显微镜下观察两组去龋后窝洞内牙本质碎屑形成情况,显微超声组明显少于涡轮机组(P<0.01);两组去龋所需时间具有显著性差异,涡轮机组较显微超声组快(P<0.05)。结论:显微超声去龋技术是一种可以改善去龋过程中酸痛感,提高去龋后窝洞内清洁度的好方法。

Abstract:Objective: To evaluate the clinical effects of micro-ultrasonic removing necrotic tissue on caries. Methods: Thirty patients with dentinal caries were randomly divided into two groups. The experiment group was excavated with ultrasonic tips and the control group with handpieces. The sensitivity of pain, dentin debris after lesions removal, and time consumption were compared. Results: All patients of the experiment group felt painless or minor aches while only 53.3% patients of the control group had the same feeling. There was significant difference between two groups (P<0.05).The dentin debris of micro-ultrasonic group was significantly less than that of handpieces group (P<0.01).The time consumption was also statistically different (P<0.01). Conclusion: The micro-ultrasonic technology is an excellent method to relieve pain and improve the cleanliness of the caries.
Keywords:Micro-ultrasonic   Caries removal   Pain   Dentin debris   Time consumption
