目的：探讨不同外科暴露术式的选择对助萌后腭侧阻生尖牙和邻牙牙周状况的影响。方法：选择30例单侧上颌腭侧阻生尖牙患者，随机分为2组，每组15例，分别采用开放式和闭合式方法助萌。在去除矫治器3个月后进行牙周状况的检查，测量阻生尖牙及邻牙的牙周袋深度（ PPD）、龈退缩量（ GR）、牙龈出血指数（ BI）、角化龈（ KG）宽度和骨支持量（ BS）。结果：开放组与闭合组的阻生尖牙及邻牙的PPD、GR、BI、KG宽度和BS的差异无统计学意义（P均＞0．05）。开放组阻生尖牙的牵引萌出时间及正畸治疗时间短于闭合组（t＝3．422和2．351，P＜0.05）。结论：外科暴露术式的选择对助萌后腭侧阻生尖牙和邻牙的牙周状况影响不大。

Aim:To evaluate post-treatment periodontal status of palatally impacted canines and adjacent teeth treated by open technique with free eruption and closed technique .Methods:The subjects comprised 30 patients treated for unilat-eral palatally impacted maxillary canines and examined 3 months after removal of the fixed appliance .The group 1 com-prised subjects treated by open technique with free eruption ( n=15 ) and group 2 by closed technique ( n=15 ) .Post-treat-ment examination comprised periodontal and radiographic examination .Results:There were no significant differences with respect to periodontal pocket depth , gingival recession , bleeding index , width of keratinize gingiva or bone support ( P >0.05).The time required to achieve eruption of the impacted canine and duration of treatment were shorter in group 1 than those in group 2(t=3.422 and 2.351,P<0.05).Conclusion:Choice of surgical method is not associated with any signifi-cant differences in post-treatment periodontal status of palatally impacted canines and adjacent teeth .
