Randomized clinical trial of different adhesion strategies in noncarious cervical lesion restorations: 1-year follow-up.

Objectives: The purpose of the present prospective and randomized clinical trial was to evaluate the clinical performance of noncarious cervical lesions (NCCLs) restored with different adhesion strategies on the dental substrate.

Method And Materials: An adhesive restorative system (Single Bond Universal/ Z350XT) with and without selective enamel conditioning was evaluated, as well as a resin-modified glass-ionomer cement (Vitremer), with and without pretreatment with ethylenediaminetetraacetic acid (EDTA). Two operators placed a total of 200 restorations in 50 patients (four restorations per patient).
