This randomized, single-blind, placebo-controlled clinical trial aims to evaluate the effect of an experimental gel based on Acmella oleracea (jambú) extract, associated or not with fluoride, in reducing dentin hypersensitivity (DH) in non-carious cervical lesions. The volunteers were randomized into 4 groups according to the treatments applied: CT (control), NP (potassium nitrate), AO (Acmella oleracea) and AF (Acmella oleracea associated with fluoride). Prophylaxis with pumice stone and water was performed on the previously selected teeth and, subsequently, the gels were applied to the cervical region with a microbrush, rubbed for 10 seconds, and remained on the tooth surface for 10 minutes. Three gel application sessions were performed, with 1-week interval between them. The DH evaluation was performed at four time points: baseline (before the first session), T1 (before the second session), T2 (before the third session) and T3, one week after the final application of the products.
