عنوان انگلیسی Effect of the Type of Restorative Material on Bonding Efficacy and Microleakage of a Self-Etching Adhesive System
چکیده انگلیسی مقاله Background: Prompt L-Pop is a self-etching dentin adhesive, which is recommended to use with both compomers and composite resins. The aims of this investigation were to determine and compare the microleakage, shear bond strength, and shear push out strength of composite and compomer to dentin with application of Prompt L-Pop as adhesive system. Methods: After application of Prompt L-Pop on the occlusal dentinal surfaces of 24 intact molar teeth, the specimens were divided into two groups (n=12). Composite resin(Filtec Z250) and compomer (F2000) were used to dentinal surfaces of group 1 and 2 respectively, using a plastic mold. Twenty-four truncated cavities were prepared in 24 horizontal occlusal coronal dentinal wafer. After application of Prompt L-Pop, the specimens divided into two groups (n=12), and the cavities in group 1 and 2 were filled with composite and compomer respectively. After application of Prompt-L-Pop on the surfaces of 20 class V cavities, the cavities were randomly divided into two groups (n=10), and were restored with composite resin and compomer respectively. The bond strength values and microleakage scores of groups were evaluated. Results: Compomer material revealed more but not statistically significant different means (SD) of shear bond strengths (Mpa) and shear push out strength (MPa). There were no significant differences in enamel and also dentinal microleakage scores, between two groups (p>0.05). Conclusion: Improving bonding efficacy and microleakage result of compomer in this study, would be because Prompt LPop is a water based material and therefore chemically more compatible with hydrophilic restorative materials, such as compomers.
