无论治疗目标是再生、预防还是保守，在动物和人类试验中，牙根表面吸收、强直（替代吸收）和牙槽骨吸收都是牙周愈合的常见后遗症。本报告描述了一例进行性颈椎根吸收患者接受牙周再生治疗与引导组织再生（GTR）。一名46岁妇女因严重牙周炎就诊。在18个月的时间里，在非手术和手术治疗期间，在x线片上诊断出角度缺陷，在24和25近端发现复发出血的牙周袋（6 mm）。无牙根龋。在这一区域进行牙周手术GTR。术后无立即并发症。两年后，临床和x线检查显示牙龈萎缩，牙周袋出血（6mm），部分暴露了25例严重的近端颈椎吸收。根面无龋。手术检查后，切除了25根。随后准备根进行组织学分析。吸收腔几乎覆盖了完整的骨下骨质上方的整个颈椎近端表面，并被大量CD68（-）覆盖，包括单核和多核细胞。在x线片显示的中心区域，蛀牙渗透到根管中，没有发现牙根龋的迹象。
ROOT SURFACE RESORPTION, ANKYLOSIS (replacement resorption) and alveolar bone resorption are not uncommon sequelae to periodontal healing in both animal and human trials whether the treatment objective is regenerative, preventive, or conservative. The present report describes a case with progressive cervical root resorption in a patient who received periodontal regenerative treatment with guided tissue regeneration (GTR). A 46-year-old woman was referred for treatment of severe periodontitis. Remaining radiographic attachment was less than 50%, Following a period of 18 months, during which non-surgical and surgical therapies were performed, angular defects were diagnosed on radiographs and recurrent bleeding periodontal pockets (6 mm) were found in the proximal areas of 24 and 25. Root caries was not present. Periodontal surgery with GTR was performed in this area. No immediate postsurgical complications were noted. Two years later, clinical and radiographic examinations revealed gingival recession with bleeding periodontal pockets (6 mm) which had partly uncovered severe proximal cervical resorptions in 25. Root surface caries was not present. Following surgical inspection, the root of 25 was removed. The root was subsequently prepared for histological analysis. Resorption cavities covered almost the entire cervical proximal surface of the root above intact infracrestal cementum and were covered by numerous CD68(-), both mononuclear and multinucleated cells. In a central area as indicated on the radiographs, the cavities penetrated into the root canal, There was no evidence of root caries.
