Abstract:

BACKGROUND: In the clinical course, dental prostheses often fall off together with adhesive materials or produce small bleeding holes; therefore, it is of clinical significance to explore the effect of binders applied via different ways on the bonding performance of total-etch resin cements with the dentin.

OBJECTIVE: To compare the effects of binders used via different ways on the bonding performance of total-etch resin cements with the dentin.
METHODS: Ninety second molars which were freshly extracted from caries-free people were enrolled and randomized into three groups. Enamel crowns were polished and rinsed with water at room temperature to expose the dentin that was used to prepare the bonding surface. Then, these specimens were treated with no binder (control), total-etch resin cements with illumination, and total-etch resin cement with no illumination, respectively. Micro-tensile bond strength was detected immediately after treatment and after ageing treatment.
RESULTS AND CONCLUSION: Immediately after treatment, the micro-tensile bond strength was (8.089±3.431) MPa for the control group, (11.671±2.561) MPa for the group of total-etch resin cements with no illumination, and (8.821±2.513) MPa for the group of total-etch resin cements with illumination, and there were significant differences between groups (P < 0.05). After ageing treatment, the micro-tensile bond strength was changed to (1.069±0.421), (7.621±2.061), (4.821±1.513) MPa in these three groups, respectively, and there were also significant differences between groups (P < 0.05). These findings indicate that the binder treatment with no illumination is an optimal method for the binding between total-etch resin cements and the dentin.
