口腔内镜辅助高速涡轮钻拔除阻生智齿的临床研究

目的探讨口腔内镜辅助高速涡轮牙钻法拔除下颌阻生智齿的临床疗效。方法随机选取280例需拔除下颌阻生智齿的患者,分为口腔内镜辅助高速涡轮钻(实验组,130例)和单纯高速涡轮牙钻法(对照组,150例)。对比观察两组平均手术时间及术后肿胀、疼痛、张口受限及干槽症等并发症的发生情况。结果实验组与对照组患者下颌阻生智齿分布比较,差异无统计学意义(P>0.05)。实验组患者下颌阻生智齿平均拔除时间较对照组明显缩短,差异有统计学意义(P<0.05)。实验组术后肿胀、疼痛及张口受限等并发症发生率明显低于对照组,差异有统计学意义(P<0.05)。实验组与对照组干槽症发生率差异无统计学意义(P>0.05)。结论口腔内镜辅助高速涡轮牙钻法拔除下颌阻生智齿能显著缩短手术时间,减少患者术后并发症,值得临床推广。

Clinical Evaluation of the Extraction of Impacted Mandibular Third Molar by High-speed Turbine Assisted by Intraoral Camera System

Objective To observe the clinical curative effects of high-speed air turbine in extraction of impacted mandibular third molar assisted by intraoral camera system.Methods A total of 280 impacted mandibular third molars included in this study were randomly assigned to two groups:the experimental group and the control group,to which the high-speed turbine assisted by intraoral camera system method and high-speed turbine method were applied respectively.The average extraction time and postoperative complications such as swelling,pain,limition of mouth opening,dry socket ect,were compared between the two groups.Chi-square test and t test were used to statistical analysis.Results No sinigficant difference was noted in distribution mandibular third molar between two groups(P>0.05).The average extraction time was shorter,and the incidence of postoperative complications except dry socket was lower in experimental group than in control,and the difference was significant(P<0.05).Conclusion The high-speed turbine assisted by intraoral camera system can sinigficantly shorten operative time and reduce postoperative complications during the extraction of wisdom teeth,which is worthy to be generalized in clinic.
