Bond strength of adhesive systems to human tooth enamel.
The purpose of this study was to evaluate in vitro three adhesive systems: a total etching single-component system (G1 Prime & Bond 2.1), a self-etching primer (G2 Clearfil SE Bond), and a self-etching adhesive (G3 One Up Bond F), through shear bond strength to enamel of human teeth, evaluating the type of fracture through stereomicroscopy, following the ISO guidance on adhesive testing. Thirty...
متن کاملTooth whitening effects on bracket bond strength in vivo.
OBJECTIVE To test the hypothesis that there is no difference between the bracket survival rate of brackets bonded to bleached and unbleached teeth. MATERIALS AND METHODS Thirty-eight patients who required comprehensive orthodontic treatment were included in the study. A split mouth technique was used with one arch exposed to in-office whitening gel containing 38% hydrogen peroxide for 30 minu...
متن کاملShear bond strength of two adhesive materials to eroded enamel.
AIM To evaluate the bond strength of one etch-and-rinse adhesive system and one resin-modified glass ionomer cement to sound and eroded enamel. MATERIALS AND METHODS Forty-eight bovine incisors were embedded in acrylic resin and ground to obtain flat buccal enamel surfaces. Half of the specimens were submitted to erosion challenge with pH-cycling model (3x/cola drink for 7 days) to induce ero...
متن کاملAdhesive system affects repair bond strength of resin composite
Purpose This study evaluated the effects of different adhesive systems on repair bond strength of aged resin composites. Materials and Methods Ninety composite discs were built and half of them were subjected to thermal aging. Aged and non-aged specimens were repaired with resin composite using three different adhesive systems; a two-step self-etch adhesive, a two-step total-etch adhesive and...
متن کاملBond strength of adhesive resin cement with different adhesive systems
BACKGROUND To assess the immediate bond strength of a dual-cure adhesive resin cement to the hybridized dentin with different bonding systems. MATERIAL AND METHODS Fifty-six healthy human molars were randomly divided into 7 groups (n=8). After 3 longitudinal sections, the central cuts were included in PVC matrix and were submitted to dentin hybridization according to the groups: G1 - etch & r...
