Abstract：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.
