RMGIC and E-RMGIC presented more alteration in surface texture than SBU and E-SBU. SBU had lower retention at four years than at baseline. Decreased alpha scores for marginal integrity and marginal discoloration were observed for all groups after four years when compared to baseline. Survival curves, related to retention, presented no statistical differences among groups (<em>p</em> = 0.315).</div></div><div><h3>Conclusions</h3><div>NCCLs restored with ionomer had more reduction in surface luster than resin composite restorations. The use of selective enamel etching promoted less loss of retention for universal adhesive. The increase of initial marginal defects occurred for all types of adhesion strategies.</div></div><div><h3>Clinical relevance</h3><div>The use of selective enamel etching cause less loss of retention for universal adhesive used in NCCL.
