Abstract：AIM:To investigate the efficacy of periodontal guided tissue regeneration technology on deep periodontal pockets of distal mandibular second molars.METHODS:15 patients with 20 mandibular second molars subbony defects≥3 mm in the distal surface and had a history of impacted third molar extraction admitted in the Department of Periodontology of Dongguan Jianli Stomatological Hospital,during July 2021 to July 2023.6 weeks after the periodontal basic treatment,found probing depth(PD)≥6 mm,and probing bleeding,then periodontal guided tissue regeneration was performed.Bio-Oss bone powder is used in combination with absorbable collagen membranes.Before surgery,6 months and 12 months after surgery,clinical indicators included PD and after surgery,clinical indicators,PD,gingival sulcus bleeding index(SBI),tooth mobility(TM),clinic attachment loss(CAL),periapical radiograph were examined.And statistical analysis was performed.RESULTS:Compared with the preoperative periodontal pocket PD,gingival sulcus SBI decreased significantly,TM was improved,the clinical CAL was significantly reduced,and the clinical attachment recovery was satisfactory,and periapical radiograph showed that the bone defect with sufficient bone filling images,which was statistically significant(P＜0.05),and the difference between the indexes at 12 months after surgery and 6 months after surgery was not statistically significant(P＞0.05).CONCLUSION:Periodontal guided tissue regeneration can achieve good results in the distal deep periodontal pockets of mandibular second molars after extraction of impacted third molar.
