Abstract

The gingival recession is frequently associated with non-carious cervical lesion. When the two lesions are associated resulting in a combined lesion, it may have a different treatment prognosis compared to the lesions alone. The literature shows just few studies that propose a multidisciplinary approach (restoration of the cervical lesion and surgery for root coverage) to optimize the treatment of this combined lesion. However, the proposed approaches have limitations and optimal clinical protocol for the treatment of these lesions has not been established yet. The aim of this study is to evaluate a new multidisciplinary protocol by means of a randomized controlled clinical trial. Twenty four patients presenting the combined lesion will be randomly allocated to one of the following groups: Test group (n = 12), partial restoration of cervical lesion and surgery for root coverage with connective tissue graft (CTG + PR) and control group (n = 12), planing of the cervical lesion and surgery for root coverage with connective tissue graft (CTG). The groups will be compared as to bleeding on probing (BOP), plaque index (IP), relative gingival recession (RGR) clinical attachment level (CAL), decrease of dentin hypersensitivity (DH) and aesthetic evaluation (AE) at baseline, 45, 60, 90 days, and 6 months after the procedure. The parameters of height, width and depth of the cervical lesion (CLH, CLW and CLD), height and thickness of keratinized tissue (KTH and KTT), height and width of papillae (PH, PW), height of bone crest (HBN) and the gingival margin position in the immediate postoperative period (MPIPP) will be used as independent variables in a multiple linear regression model to evaluate their influence each one on the final outcome of the procedures.
