目的探讨三段式横断法拔除下颌低位水平阻生智齿对邻牙的影响。方法收集2008年7月至2009年12月中山大学光华口腔医学院附属口腔医院收治的下颌双侧低位水平阻生牙患者62例,共124颗牙。将患者左右侧阻生牙随机分成A、B两组,每组62颗。A组采用三段式横断法拔除阻生牙,B组采用两段式横断法拔除阻生牙。比较两组术后1周邻牙温度敏感、叩痛及松动等不良反应发生情况。结果术后1周,A组患者邻牙的温度敏感、叩痛及松动等不良反应的发生率均明显低于B组患者,差异均有统计学意义(P<0.05)。结论在拔除下颌低位水平阻生牙时,三段式横断法可以减少邻牙术后不良反应的发生,是一种值得在临床中推广的拔牙术式。
Objective To investigate the effect of three-stage transection on the adjacent teeth with low-level impacted wisdom teeth. Methods Totally 62 teeth with bilateral low level breech teeth were collected from July 2008 to December 2009 at the Stomatological Hospital Affiliated to Guanghua School of Stomatology, Sun Yat-sen University. A total of 124 teeth were collected. Left and right patients with impacted teeth were randomly divided into A, B two groups, each of 62. In group A, the three-stage transverse method was used to remove the impacted teeth. In group B, the two-stage transverse method was used to remove the impacted teeth. The adverse reactions such as temperature sensitivity, percussion pain and loosening of adjacent teeth were compared between the two groups at 1 week after operation. Results One week after operation, the incidence of adverse reactions such as temperature sensitivity, percussion pain and loosening of adjacent teeth in group A were significantly lower than those in group B (P <0.05). Conclusions The three-stage transection method can reduce the occurrence of postoperative adverse reactions in removal of the lower level of impacted teeth. It is a kind of extractive technique worthy of promotion in clinic.
