“…Gingival recession is clinically characterized by apical displacement of the marginal gingiva with exposure of the root surface and has a multifactorial etiology (Wennstrom, 1966). It can be related to anatomical factors, such as bone fenestrations and dehiscences, abnormal position of teeth in the arch, incorrect sequence of tooth eruption and individual tooth shape (Alldritt, 1968), vestibulopalatine dimension of soft and hard tissues (Wennstron et al, 1987) and amount of inserted gingiva (Novaes & Palioto, 2019); physiological, such as orthodontic movement outside bone boundaries (Wennstron et al, 1987); and pathological factors, such as incorrect use of dental floss and tapes (Everett & Kunkel, 1953), Capítulo 88 traumatic brushing (Khocht et al, 1993), perioral and intraoral 'piercings' (Campbell et al, 2002), trauma associated with malocclusion (Tugnait & Clerehugh, 2001), inflammation caused by biofilm accumulation (Baker & Seymour, 1976) and lesions caused by the herpes virus (Prato et al, 2002). Among the possible treatments for gingival recessions is root coverage, where the main indications are the patient's aesthetic demands, inconsistent and disharmonic gingival margin, reduction of dentin hypersensitivity, and the prevention of caries and cervical non-carious lesions (Chambrone & Tatakis, 2015;Zucchelli & Mounssif, 2015).…”
