Table 2

Composition and manufacturer’s instructions of adhesive systems used in the study.

Adhesive	Composition	Manufacture	Technique
G-Bond	4-MET, phosphate ester monomer, UDMA, acetone, water, microfiller, and photoinitiator	GC Corp.; Tokyo, Japan	(i) Shake the bottle thoroughly prior to dispensing; (ii) Immediately apply to the prepared enamel and dentin surfaces using the disposing applicator; (iii) Leave undisturbed for 5–10 seconds; (iv) Dry thoroughly for 5 seconds with oil free air under maximum air pressure. The final results should be a thin, rough, adhesive film with the appearance of frosted glass and which doesn’t visibly move under further air pressure; (v) Light cure for 10 seconds
OptiBond-All-In-One	GPDM, GDM, HEMA, Bis-GMA, water, ethanol, acetone, silica, CQ, and sodium hexafluorosilicate	OP; Kerr; Orange, CA, USA	(i) Shake adhesive bottle briefly. (vigorously for 10 seconds); (ii) Using the disposable applicator brush, apply a generous amount of OptiBond-All-In-One adhesive to enamel/dentin surface. Scrub the surface with a brushing motion for 20 seconds; (iii) Apply a second application of OptiBond-All-In-One All-In-One adhesive with a brushing motion for 20 seconds; (iv) Dry the adhesive with gentle air first and then medium air for at least 5 seconds with oil-free air; (v) Light cure for 10 seconds
