摘　　要：目的评价自体牙本质颗粒结合富血小板纤维蛋白治疗Ⅱ度根分叉病变的临床效果。方法牙周基础治疗的下颌第一磨牙Ⅱ度根分叉病变患者共32例,16例患者的16颗牙,用自体牙本质颗粒结合PRF植入骨缺损区并覆PRF膜,对照组的16例患者的16颗牙,用Bio-Oss植入骨缺损区并覆盖胶原膜,术后3、6、12个月回访,通过临床检查及X线检查评定疗效。结果两组术后牙周袋深度(PD)、附着丧失(AL)、根分叉水平探入深度(HPD)均明显减少,有显著性差异(P<0.05),两组术后根分叉区骨密度显著增加,且有显著性差异(P<0.05)。结论自体牙本质颗粒结合PRF治疗Ⅱ度根分叉病变临床效果明显。Objective To evaluate the efficacy of the autogenous dentin particles combining PRF in treating class Ⅱ furcation involvement. Methods 32 patients without systemic disease but with mandibular first molar class Ⅱ furcation involvement,who had been treated through initial therapy were selected. In the experiment group,16 patients with 16 teeth,the autogenous dentin particles and PRF were placed in the areas with furcation defect,while in the control group,another 16 patients with 16 teeth,Bio-Oss and collagen membrane were used. The patients were followed up at 3,6,12 months after operation. The efficacy was evaluated with clinical parameters and X-ray examination. Results The following periodontal indexes including PD,AL,HPD significantly decreased in both groups after operation（P〈0. 05） The alveolar bone density obviously increased in two groups（P〈0. 05）. Conclusion The clinical effect of the treatment on class Ⅱ furcation involvement by autogenous dentin particles with PRF is remarkable.
