Periodontal practice focuses not only on biological and functional problems affecting the periodontium, but also on improving the aesthetics of the periodontium. The depth of the vestibule is one of the factors that may influence the periodontal condition. A shallow vestibule may lead to exposure of the root surface due to apical migration of the connecting epithelium, deterioration of aesthetics, root hypersensitivity and root caries. Deepening the vestibule can facilitate daily hygiene activities, improve patient comfort and positively change conditions in this area.

Key words: gingiva, oral vestibule, vestibular depth.
