2种切开翻瓣法在上前牙显微超声根尖手术中的临床疗效研究

The effects of two kinds of incisions and flap designs on the maxillary anterior tooth endodontic microsurgery

纳入上前牙需根尖手术的患者40例,随机均分为2组(n=20),A组选半月形切口翻瓣术,B组选传统梯形切口翻瓣术,观察2组病例术后3、7d术区肿胀、疼痛、愈合情况,结果A组术后3d的疼痛、肿胀差异度指标均显著低于B组,术后7d的疼痛指标低于B组(P<0.05),术后2组的切口愈合等级无统计学差异(P>0.05)。

40 patients requiring maxillary anterior tooth endodontic microsurgery were randomly divided into A and B groups(n=20),the patients in group A received semilunar incision flap and those in group B underwent traditional trapezoid incision flap.The effects of two kinds of incisions and flaps on swelling,pain and healing were observed on the 3rd and 7th day postoperatively.The results showed that post-operative pain and swelling of 3rd day in group A were significantly lower than those in group B,postoperative pain of 7th day was lower than that of group B(P<0.05),there was no significant difference in incision healing between the 2 groups(P>0.05).
