Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Retraction and total-etch
Gingival displacement with a gingival cord (#0, #00 or #000) prior to the restoration. Application of total-etch adhesive system: enamel and dentin etched with 35% phosphoric acid, wash, dry, two layers of primer/bond application with a brush and photoactivated for 20 seconds.
Gingival displacement
Gingival displacement with a gingival cord (#0, #00 or #000) with specific spatula.
Enamel and dentin etched
Enamel and dentin etched with 35% phosphoric acid for 30 and 15 seconds, respectively.
Wash and dry
Wash and dry with absorbent paper.
Total-etch adhesive system
Two layers of pirmer/bond on enamel and dentin with a brush.
Photoactivated
Photoactivated for 20 seconds
No retraction and total-etch
Application of total-etch adhesive system: enamel and dentin etched with 35% phosphoric acid, wash, dry, two layers of primer/bond application with a brush and photoactivated for 20 seconds.
Enamel and dentin etched
Enamel and dentin etched with 35% phosphoric acid for 30 and 15 seconds, respectively.
Wash and dry
Wash and dry with absorbent paper.
Total-etch adhesive system
Two layers of pirmer/bond on enamel and dentin with a brush.
Photoactivated
Photoactivated for 20 seconds
Retraction and self-conditioning
Gingival displacement with a gingival cord (#0, #00 or #000) prior to the restoration. Application of self-conditioning adhesive system: selective enamel etched with 35% phosphoric acid, wash, dry, one layer of acid/pirmer on enamel and dentin with a brush, one layer of bond with a brush and photoactivated for 20 seconds.
