目的：：探讨下颌低位阻生第三磨牙拔除术后牙槽窝应用富血小板血浆对第二磨牙远中牙周探诊深度( PD)和附着丧失( AL)的影响。方法：选取C1分类下颌阻生第三磨牙患者40名,且拔牙术前第二磨牙远中PD>7.5 mm、AL>6 mm,患者随机分为两组(n=20)。阻生牙拔除后,实验组牙槽窝内置入富血小板血浆；对照组牙槽窝由血凝块充盈。拔牙术后6个月测量第二磨牙远中PD、AL,并比较两组之间差异。结果：术前两组患者PD、PL无显著差异(P>0.05)；术后6个月,与对照组相比,实验组牙槽窝内置入富血小板血浆能明显降低第二磨牙远中PD、AL值(P<0.05)。结论：下颌阻生第三磨牙拔除术后牙槽窝置入富血小板血浆有利于第二磨牙远中牙周组织健康。

AIM:To investigate the clinical effects of platlet rich plasma ( PRP) used in the socket on the distal probing depth( PD) and periodontal attachment loss( AL) of lower second molar after C1 impacted wisdom tooth extraction. METHODS:40 patients with C1 impacted wisdom teeth were divided into 2 groups(n=20). The distal PD and AL of lower second molars were no less than 7. 5 mm and 6 mm respecively before tooth extraction. In experi-ment group PRP was put in the sockets after tooth extraction. In control group the sockets were not treated. Before and 6 m after operation PD and AL were measured, statistical differences were analyzed. RESULTS:Before operation PD and AL in the 2 groups were not statistically defferent(P>0. 05), 6 m after operation PD and AL in experiment group were lower than those in control group(P<0. 05). CONCLUSION: Using PRP in the socket after extraction of im-pacted wisdom tooth is helpful for the distal periodontal health of lower second molar.
