NCT02434601

Brief Summary

The surface of non-carious cervical lesions (LCNC) is a challenge to adhesive systems, it presents a dentin layer sclera hypermineralized, presence of bacteria and lack of mechanical retention, so this study aimed to evaluate the influence of different surface treatments on LCNC through a randomized clinical trial. Patients with LCNC were referred to the study and selected according to the inclusion criteria, such as the presence of at least 3 LCNC. Three different types of surface treatment were carried out in LCNC: control group, 15 seconds of etching dentin; Group I, acid etching of dentin in 30 seconds; and group II, cavity prophylaxis with ultrasound for 30 seconds. The remaining steps of the adhesive and restorative procedure was the same for all groups, following the material manufacturer's recommendations. Evaluations of restorations will be carried out in periods of one week (baseline), six months, one year, two years and three years as of tooth sensitivity, integrity and color change. Data will be analyzed by McNemar and chi-square test.

Study Arms (3)

Treatment of Dentin Surface

OTHER

Treatment of Dentin Surface: Restoration made following the protocol recommended by the manufacturer of the materials.

Procedure: Treatment of Dentin Surface

Dentin Surface

EXPERIMENTAL

Treatment of Dentin Surface: Increased etching dentin for 15 seconds to 30 seconds

Procedure: Dentin Surface

Treatment

EXPERIMENTAL

Treatment of Dentin Surface: Intervention with the cavity prophylaxis probe ultrasound blunt applied for 30 seconds in Surface hypermineralized non-carious dentin cervical lesions. Therefore, the restoration was done following the protocol recommended by the manufacturer of the material.

Procedure: Treatment

Interventions

* Experimental Group 1: Increase the etching time to 30 seconds, performed with phosphoric acid gel at 37%, prior to application of the resin adhesive. * Experimental Group 2: Prophylaxis cavity probe / blunt tip of ultrasound, applied for 30 seconds on the dentin surface hypermineralized of cervical lesions non-carious. Both restorative procedures were performed using a conventional adhesive system and composite restorative nanoparticulate.
