Abstract

Background and Aims: Radiopacity is an essential requirement for all restorative materials. Radiopaque materials allow the dentist to diagnose and assess radiographically the restoration, primary caries, assessment of contours, overhang and secondary caries. The aim of this study was to evaluate the Radiopacity of two types of dental bases and liners in comparison whit dental structure using a Digital radiography system. Materials and Methods: Two classes of materials were prepared: 1 mm and 2 mm thickness disks for Glass inomer and 1 mm and 0. 5 mm thicknesses for Dycal. Specimens of enamel and dentine with the same thicknesses were obtained. As a control, an aluminum step wedge was used. Samples were positioned over a phosphor-ray, plate of min ray soredex system, exposed, and the images were analyzed using the contour dent software. ANOVA analysis was used to investigate the significance of differences among the groups. For pairwise comparisons, the Bonferroni test was applied (P<0. 005). Results: 0. 5 mm diameter of self-cure and light cure Dycal and enamel, presented radio-opacity higher than that of dentine, except for the light cure Dycal that had Radiopacity lowers than enamel. 1 mm diameter of all the groups presented higher Radiopacity than dentin. Light cure and self-cure Glass inomer and self-cure Dycal presented Radiopacity higher than enamel. Enamel showed radipacity higher than light cure Dycal in 2 mm diameter self-cure. Light cure Glass inomer presented Radiopacity higher than that of enamel and dentin. Conclusion: The increased thickness of the materials evaluated increased their radio-opacity. It was concluded that all the materials had lower radiopaaty than dentin. Only enamel showed higher Radiopacity than light-cured Dycal.
