目的评价齿槽外科中应用无痛微创拔牙技术的临床效果。方法对2014年1月至2015年6月辽宁省人民医院口腔科收治的96例拔牙患者,按照随机数字表法将其分为观察组和对照组,每组48例。观察组患者采用无痛微创拔牙技术拔牙,对照组患者采用传统拔牙方法拔牙。对比两组患者的拔牙手术时间、术中疼痛情况及术后感染情况,并且进行拔牙效果评价。结果观察组患者的拔牙手术时间明显短于对照组患者,术中疼痛发生率、术后感染率也明显低于对照组,差异均有统计学意义(均P<0.05)。观察组的拔牙效果评价为Ⅰ级的比例为93.75%,明显高于对照组的66.67%;而Ⅲ级的比例为2.08%,明显低于对照组的10.41%,差异均有统计学意义(均P<0.05)。结论在齿槽外科中应用无痛微创拔牙技术拔牙,具有手术时间更短、术中疼痛发生率和术后感染率更低的优点,值得临床推广。
Objective To evaluate the clinical effect of painless minimally invasive extraction in alveolar surgery. Methods From January 2014 to June 2015, 96 cases of tooth-extraction patients admitted to Department of Stomatology, Liaoning Provincial People’s Hospital were divided into observation group and control group according to random number table method, with 48 cases in each group. Patients in the observation group were treated with painless minimally invasive extraction technique, while those in the control group were extracted by traditional extraction method. Tooth extraction surgery time, intraoperative pain and postoperative infection were compared between two groups of patients, and tooth extraction effect was evaluated. Results In the observation group, the operation time of tooth extraction was significantly shorter than that of the control group. The incidence of intraoperative pain and postoperative infection was also significantly lower than that of the control group (all P <0.05). The rate of tooth extraction in the observation group was 93.75%, which was significantly higher than that of the control group (66.67%), while the grade Ⅲ was 2.08%, which was significantly lower than that of the control group (10.41%), both of which were statistically significant P <0.05). Conclusion The application of minimally invasive minimally invasive extraction of tooth extraction in alveolar surgery has the advantages of shorter operation time, lower intraoperative pain rate and lower postoperative infection rate, which is worthy of clinical promotion.
