一项临床试验被用来研究不同牙周手术方式对口腔卫生保持在最佳水平的患者的牙周组织愈合能力的影响。50名患者被分成五组，参与了这项研究。在初步检查和术前治疗后，不同的患者组接受了以下外科手术之一：1)根尖重置皮瓣手术，包括消除骨缺损；2)根尖重置皮瓣手术，包括刮除骨缺损但不去除骨；3)“Widman瓣”技术，包括消除骨缺损；4)“Widman瓣”技术，包括刮除骨缺损但不去除骨；5)牙龈切除，包括刮除骨缺损但不去除骨。手术后，所有患者接受口腔卫生指导和专业清洁牙齿，每两周一次，为期两年。结果表明，无论采用何种手术技术去除牙袋，牙周病都可以治愈，避免牙周组织的进一步破坏。然而，不同的手术技术促进了不同程度的支持组织的再生。避免骨切除，确保牙槽骨完全覆盖，可获得最佳愈合。
A clinical trial was undertaken to study the healing capacity of the periodontal tissues following different modes of periodontal surgery in patients whose oral hygiene was professionally maintained at an optimal level. Fifty patients, distributed into five groups, participated in the study. Following an initial examination and presurgical treatment, the various patient groups were subjected to one of the following surgical procedures: 1) the apically repositioned flap operation including elimination of bony defects, 2) the apically repositioned flap operation including curettage of the bony defects but without removal of bone, 3) the "Widman flap" technique including elimination of bony defects, 4) the "Widman flap" technique including curettage of the bony defects but without removal of bone, 5) gingivectomy including curettage of the bony defects but without removal of bone. After surgery, all patients received oral hygiene instruction and professional cleaning of the teeth once every 2 weeks during a 2-year period. The results showed that periodontal disease can be cured and further destruction of the periodontal tissues avoided irrespective of the surgical technique utilized for pocket elimination. Different surgical techniques, however, promoted varying degrees of regeneration of the supporting tissues. The most favourable healing was obtained when resection of bone was avoided and when complete coverage of the alveolar bone was ensured.
