Radiological and clinical dental investigation. (A) The panoramic X-ray at age five years revealed extensive alveolar bone loss on teeth 82, 83, and 84 with furcation involvement in the latter. Teeth 71 and 81 were lost due to periodontal bone loss at age four years. (B) Lack of attached gingiva is evident in the mandibula; the thin and fragile mucosa extends to the free gingival margin and the interdental papillae, which are normally keratinized and “thick”. Severe gingival recession up to 6 mm was diagnosed in all teeth but numbers 75 and 85.
