Matriz dérmica acelular para recobrimento radicular em recessão gengival unitária: relato de caso

Introduction: Gingival recession (GR) is defined as the apical migration of the gingival margin, resulting in root exposure in the oral environment, it is known that among its multifactorial etiology the use of orthodontic appliance is cited as a risk factor for GR in patients with a thin periodontal phenotype. Objective: This paper aims to report a case of single root coverage using acellular dermal matrix (MDA) graft. Case Report: Female patient, 24 years old, non-smoker and without systemic alterations, attended the dental clinic of a college in northern Brazil with the main complaint of dentin hypersensitivity in the posterosuperior region. The clinical examination showed stage I type 1 recession in tooth 25 associated with orthodontic movement in the buccolingual direction, the GR of tooth 15 had 2mm (cervico-apical direction) and 1mm (mesiodistal direction), it was also observed Thin scalloped phenotype, no interproximal bone loss, no bleeding on probing and dental biofilm. The indicated treatment was root coverage using the coronal slip technique with MDA fixed with sutures. Conclusion: Given the above, we verified that the clinical results reported in this study indicated a great clinical result with excellent predictability of success, increased keratinized mucosal band and clinical insertion gain.
