【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(P0.05);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(P0.01);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(P0.05)。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 application of microultrasonic caries removal technique and traditional turbine caries removal technique. Methods: 30 teeth with similar decayed depth were randomly divided into experimental group and control group. The sensitivity to pain, the formation of dentin detritus and the time of caries removal were compared between the two groups. Results: all the patients in the experimental group felt painless or mild pain, while only 53.3% of the patients in the control group felt painless or mild pain. The results showed that there was a significant difference between the two groups in the process of caries removal (P0.05). Microscopically observed the formation of dentin debris in the cavity after caries removal in the two groups, the microultrasound group was significantly less than the turbine unit (P0.01), the time of caries removal in the two groups was significantly different, the turbine unit was faster than the microscopic ultrasonic group (P0.05). Conclusion: microultrasonic caries removal is a good method to improve the ache and the cleanness of the cavities after caries removal.
