摘　　要：目的探讨应用显微超声技术行牙半切术的临床疗效,为临床进一步推广提供依据。方法选择30例一侧基本完好,一侧病变严重的患牙,随机分为对照组和实验组,每组15颗。对照组行传统的牙半切术,实验组应用显微超声技术行牙半切术,术后1、3年后复诊评估其成功率以及边缘性牙龈炎的发生率。采用Pearson Chi-Square检验统计牙半切术的疗效,当频数少于5时则采用Fisher精确概率法,检验水准α=0.05。结果两组术后1年和3年成功率差异无统计学意义(P1=1,P3=1),实验组术后3年边缘性牙龈炎发生率低(P=0.035)。结论显微超声技术行牙半切术可以有效的保存一侧基本完好,一侧病变严重的患牙,可有效降低术后边缘性牙龈炎的发生。Objective To investigate the clinical effect of the application of micro ultrasonic technology in the treatment of dental resection, and provide the basis for its clinical application. Methods Thirty patients were randomly divided into the control and experimental group, with 15 teeth of each. One side of each tooth was basically intact, and the other side was severe lesion. The control group was treated with the traditional dental semi cut operation, and the experimental group was treated with the micro ultrasonic technique. The success rate and the incidence of marginal gingivitis were both evaluated after 1 and 3 years. Results No significant difference of the success rate was seen in the two groups （P1=1,P3=1）. The incidence of marginal gingivitis of experimental group was lower than the control group after 3 years （P=0.035）. Conclusion Microscope and ultrasonic technique for tooth hemisection surgery can effectively save the tooth with an intact half side. It can also effectively reduce the incidence of postoperative marginal gingivitis.
