Objective
To investigate the effect of curing of composite cements and a new ceramic silanization pre-treatment on the micro-tensile bond strength (渭TBS).Methods
Feldspathic ceramic blocks were luted onto dentin using either Optibond XTR/Nexus 3 (XTR/NX3; Kerr), the silane-incorporated 鈥榰niversal鈥?adhesive Scotchbond Universal/RelyX Ultimate (SBU/RXU; 3M ESPE), or ED Primer II/Panavia F2.0 (ED/PAF; Kuraray Noritake). Besides 鈥榗omposite cement鈥? experimental variables were 鈥榗uring mode鈥?(鈥楢A鈥? complete auto-cure at 21 掳C; 鈥楢A*鈥? complete auto-cure at 37 掳C; 鈥楲A鈥? light-curing of adhesive and auto-cure of cement; 鈥楲L鈥? complete light-curing) and 鈥榗eramic surface pre-treatment鈥?(鈥楬F/S/HB鈥? hydrofluoric acid (鈥楬F鈥? IPS Ceramic Etching Gel, Ivoclar-Vivadent), silanization (鈥楽鈥? Monobond Plus, Ivoclar-Vivadent) and application of an adhesive resin (鈥楬B鈥? Heliobond, Ivoclar-Vivadent); 鈥楬F/SBU鈥? 鈥楬F鈥?and application of the 鈥榰niversal鈥?adhesive Scotchbond Universal (鈥楽BU鈥? 3M ESPE, only for SBU/RXU)). After water storage (7 days at 37 掳C), ceramic-dentin sticks were subjected to 渭TBS testing.
Results
Regarding the 鈥榗omposite cement鈥? the significantly lowest 渭TBSs were measured for ED/PAF. Regarding 鈥榗uring mode鈥? the significantly highest 渭TBS was recorded when at least the adhesive was light-cured (鈥楲A鈥?and 鈥楲L鈥?. Complete auto-cure (鈥楢A鈥? revealed the significantly lowest 渭TBS. The higher auto-curing temperature (鈥楢A*鈥? increased the 渭TBS only for ED/PAF. Regarding 鈥榗eramic surface pre-treatment鈥? only for 鈥楲A鈥?the 渭TBS was significantly higher for 鈥楬F/S/HB鈥?than for 鈥楬F/SBU鈥?
Significance
Complete auto-cure led to inferior 渭TBS than when either the adhesive (on dentin) or both adhesive and composite cement were light-cured. The use of a silane-incorporated adhesive did not decrease luting effectiveness when also the composite cement was light-cured.
