The successful treatment of a large endodontically induced periradicular defect and soft tissue fenestration by combined endodontic and periodontal therapy is described. Endodontics was performed on the mandibular left central incisor, the apex was resected, and a retrograde amalgam was placed. The defect was thoroughly debrided and the exposed root surface was planed with curettes. Demineralized freeze-dried bone allograft and a nonresorbable membrane were placed over the defect and the exposed root surface. The membrane was removed in 6 months and there appeared to be bone regeneration with complete closure of the soft tissue fenestration. Endodontic therapy in combination with guided tissue regeneration and bone grafting may provide another modality of treatment for endodontically related hard and soft tissue defects.
本文描述了通过牙髓治疗与牙周治疗相结合成功治疗大型牙髓源性根尖周缺损及软组织开窗的病例。对下颌左侧中切牙进行了牙髓治疗，切除根尖后放置了逆行银汞合金充填物。对缺损进行了彻底清创，并用刮匙修整暴露的牙根表面。将脱矿冻干骨同种异体移植材料和不可吸收膜覆盖在缺损及暴露的牙根表面。6个月后取出膜，可见骨再生且软组织开窗完全闭合。牙髓治疗联合引导组织再生和骨移植可为牙髓相关的软硬组织缺损提供另一种治疗方式。
