[A decision tree for treatment of patients with gingival Stillman's cleft].

Gingival Stillman's cleft is a mucogingival triangular- shaped defect which influence on health and appearance of gingiva. Due to a lack of clinical reports, five cases of gingival Stillman's cleft were recruited in the present study. The treatment methods were selected according to the etiological factors of the defect in each patient. Satisfactory treatment responses were achieved in all cases during a 6 to 20 month follow up after the treatments. In this study, we summarized the treatment strategies in various types of gingival Stillman's cleft, so as to provide the reference for clinicians.
