[Reconstruction of soft and hard tissue around the tooth in aesthetic areas: a case report]

Gingival recession or root exposure is associated with the loss of soft and hard tissue around the root. Gingival recession not only leads to aesthetic problem, but also affects tooth function, and even causes the loss of tooth. A case was diagnosed as gingival recession of upper incisor and periodontal- endodontic combined lesion. This report included the history of disease, clinical examination, X-ray film, treatment planning, root canal treatment and sequence of periodontal disease treatment (initial therapy, local drug therapy, bone graft and guided tissue regeneration combined with double laterally positioned flaps, subepithelial connective tissue graft and coronal positioned flap). The reasons of gingival recession, the methods of root coverage and the reconstruction of soft and hard tissue were also discussed on the basis of this case.
