目的：探讨橡皮障开口器在牙周翻瓣术患者口角牵拉中的应用效果。方法选取入我院行牙周翻瓣术患者92例，左右侧分次手术，2次手术间隔时间为1周。采用自身对照研究，左右侧随机分为观察组和对照组。对照组采用传统口镜进行口角牵拉，观察组采用橡皮障开口器和传统口镜进行口角牵拉。观察2组患者手术操作时间、术后舒适度、术后即刻及术后1周创伤性口角炎发生率。结果观察组手术操作时间短于对照组（t=14.313，P<0.01），术后口腔舒适度高于对照组（Z=6.808，P<0.01），术后即刻及术后1周创伤性口角炎发生率均低于对照组（P<0.01）。结论橡皮障开口器联合传统口镜在牙周翻瓣术中可为医生提供更好的视野，缩短手术时间，提高患者舒适度，降低患者术后创伤性口角炎发生率，值得临床借鉴使用。

Objective To discuss the effect of rubber dam oral lip opener combined with mouth mirror in periodontal flap surgery. Methods Ninety-two patients undertaking periodontal flap surgery were involved. The surgery was conducted for two times in terms of the left and right sides with an interval of one week. The study was designed as a self-control study with the surgeries of the left side and the right side set as experimental group and control group randomly. For experimental group, rubber dam oral lip opener and mouth mirror were used for oral lip opening, while for control group only mouth mirror was used. The time duration of the surgery, postoperative comfort, the incidence and degree of the traumatic angular cheilitis immediately and one week post-surgery were recorded and compared. ResuIts The time duration of the surgery in experimental group was shorter than that of control group ( t=14.313, P<0.01) and patients felt more comfortable in experimental group (Z=6.808, P<0.01). The degree of traumatic angular cheilitis immediately and one week post-surgery in experimental group was lower than those in control group ( P<0.01). ConcIusion Rubber dam oral lip opener combined with mouth mirror can provide better visibility for the dentists, shorten the surgery duration, improve the comfort of the patients, and decrease the degree of the traumatic angular cheilitis, thus being a good instrument for dental clinic.
