Study Overview
Brief Summary
Gingival recession is defined as the apical displacement of gingival margin to the cemento enamel junction (CEJ) exposing the root surface (Gustavo et al 2021 ). The causative factors include faulty tooth brushing, underlying periodontal disease, malaligned tooth, high frenal attachment causing marginal gingival pull, subsequently leading to the exposure of root causing esthetic concerns hypersensitivity, plaque retention and caries to the patients. Among the various surgical treatmentstrategies, the coronally advanced flap technique (CAF) combined with connective tissue graft (CTG) is considered as the gold standard protocol in the management of gingival recession resulting in complete root coverage along with improving keratinized tissue height and gingival thickness. A recent modification by zuchelliet al (2010), known as De-epithealized gingival graft (DGG) enables the clinician to obtain collagen rich fibrous connective tissue from lamina propria of the palate, with minimal amount of fatty and glandular tissue, than the previously mentioned sub epithelial connective tissue graft harvesting techniques. However, drawbacks of harvesting autogenous grafts include palatal morbidity as a result of the secondary surgical site and the patient’s fear of pain. Studies have reported that horizontal centrifugation of PRF was superior at accumulating platelets and leukocyteswhen compared to the results from standard fixed angle centrifuges **(Richard J.Miron et al 2020).**In this clinical study we propose to compare out comes of the PRF obtained by the horizontal centrifugation method and coronally advanced flap with connective tissue graft (CTG) obtained by de-epithelized FGG for a follow up period up to 6 months
