title: [Treatment of advanced periodontal and periapical lesion caused by malformed lingual groove with guided tissue regeneration: report of one case].
abstract: This paper reported one case with severe periodontal lesions caused by malformed lingual groove treated by guided tissue regeneration. The periodontal lesion was exposed palatally after the tooth had been treated with root canal therapy, the alveolar bone and the root surface was prepared, an unabsorbable member of e-PTFE was placed into the wound,and removed after 4 weeks, the patient was followed up for 3 years. The lesion recovered well three years after the operation, all of the periodontal tissue was in a healthy condition. It is advisable that guided periodontal tissue regeneration can be used as a new method to treat periodontal destruction induced by malformed lingual groove.
