不同年龄段患者拔除下颌阻生第三磨牙的临床比较

摘要

将330例下颌阻生第三磨牙患者按18岁以下（A）、18～25岁（B）、25岁以上（C）年龄段分3组，对手术时间及术中、术后并发症进行比较，A、B、C 3组手术时间（min）分别为21．95±5．86、6．45±4．92、18．77±9．64，B 组的手术时间明显短于其他2组（P ＜0．01）；术中并发症发生率分别为2．73％、6．36％、30．91％（P ＜0．01），术后并发症发生率分别为51．82％、23．64％、66．36％（P ＜0．01）。18～25岁年龄段拔除下颌阻生第三磨牙难度小、并发症少。%330 cases of impacted mandibular third molar were divided into 3 groups,A:younger than 18 years,B:18-25-year-old,C:ol-der than 25-year.Operation time(min)of group A,B and C was 21.95 ±5.86,6.45 ±4.92 and 18.77 ±9.64(B vs A or C,P <0.01), intraoperative complication rates were 2.73%,6.36% and 30.91%(P <0.01),postoperative complication rates were 51.82%,23.64%and 66.36%(P <0.05),respectively.18-25 year-old is the suitable age for removal of impacted mandibular third molars.
