Application methods of the adhesives systems used in this study.

GroupsApplication method

XT, QC, and OL(i) Etching phosphoric acid 37%, 30 s on the enamel  
(ii) Washing for 30 s and air jet drying  
(iii) Active application of 2 layers of the adhesive (5 s)  
(iv) Using a brief air jet to evaporate the solvent and make sure there is a thin, uniform layer  
(v) Photopolymerization for 20 s.  
(vi) Resin application and photopolymerization for 10 s, each surface (mesial, distal, cervical, and incisal).
