Study: NCT05211908

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: Composite resin restoration with Self Etch adhesive protocol and absence of sclerotic dentin
Description: The adhesive system Single Bond Universal (3M Oral Care; Brazil) and a nanoparticulate composite resin Z350 XT (3M Oral Care; Brazil), shade A3B, will be the materials used in the restorative procedures.~For the D-SE group, the universal adhesive system will be applied with a disposable microbrush, actively, for 20s and then a gentle stream of air will be used for 5s to solvent evaporation, followed by light curing for 10s using the Valo Cordless light curing (Ultradent Products Inc.), in Standard mode (1000mW /cm2).~All groups will receive the restorations made following the incremental technique of insertion of composite resin (2mm per increment), which will be light cured according to the manufacturer's recommendations.

Intervention: Composite resin restoration with Seletive enamel etch adhesive protocol and absence of sclerotic dentin
Description: The adhesive system Single Bond Universal (3M Oral Care; Brazil) and a nanoparticulate composite resin Z350 XT (3M Oral Care; Brazil), shade A3B, will be the materials used in the restorative procedures.~For the D-SELETIVE group a 37% phosphoric acid will be applied only at the enamel margin for 15s, then rinsed with water for 20s, and slightly dry. The universal adhesive system will be applied with a disposable microbrush, actively, for 20s and then a gentle stream of air will be used for 5s to solvent evaporation, followed by light curing for 10s using the Valo Cordless light curing (Ultradent Products Inc.), in Standard mode (1000mW /cm2).~All groups will receive the restorations made following the incremental technique of insertion of composite resin (2mm per increment), which will be light cured according to the manufacturer's recommendations.
