摘　　要：目的跟踪观察195例拔除低位水平阻生智齿患者的临床资料,分析患者年龄对拔除低位水平阻生智齿术后愈合的影响,探讨低位水平阻生智齿的拔除时机。方法将195例患者按年龄分为﹥25岁组及≤25岁组,跟踪6个月,观察其术后肿胀、并发症、拔牙创骨质重建、邻近第二磨牙远中牙周愈合情况及骨硬板修复重建情况。结果所有患者术后肿胀、并发症与拔牙年龄无关,但术后邻牙不适在较高年龄组的发生率高于低年龄组(P﹤0.05)。术后1个月及3个月,较高年龄组的邻牙远中深牙周袋大于低年龄组(P﹤0.05);而术后6月,两组间深牙周袋无明显差异(P﹥0.05)。术后骨质高度比值,术后3个月及6月内较高年龄组低于低年龄组(P﹤0.05)。术后邻牙远中骨硬板及牙周膜间隙重建率在较高年龄组低于低年龄组(P﹤0.05)。结论对于低位水平阻生第三磨牙,越早拔除越好。OBJECTIVE To observe the healing procedure after extraction of low horizontal impacted 3rd molar and to ascertain the optimal time of the removal of the low horizontal impacted 3rd molar. METHODS 195 patients who extracted low horizontal impacted mandibular third molar were divided two groups （group with age age 〉 25 and group with age^25） . All of them were followed up for 6 months. The post-operative course was recorded including postoperative reaction, complication and periodontal examination of the next second molar. RESULTS The postoperative swelling, complication and the periodontal probing depths in 6 month after operation were not associated with the age, but the incidence of the discomfort of the next second molar （P 〈 0.05）. The periodontal probing depths at the time 1 and 3 months after operation in the age 〉 25y group were significantly higher than those in the age~〈25y group （P 〈 0.05）. The postoperative ratios of bone height in the time of 3 and 6 months after opera- tion in the age 〉 25y group was significantly lower than the age ≤ 25y group（P 〈 0.05）. The incidences of reconstruction of lamina dura and periodontal membrane space in the age 〉 25y group that of the age ≤ 25y group were significantly higher than those in the non-bony destrution group （P 〈 0.05）. CONCLUSION It is better to extract the low horizontal impacted mandibular third moler as early as possible.
