This study evaluated the effect of Compoglass restorative material placed in class-II restoration on the adjacent sound enamel. 120 extracted human impacted third molars were divided into 4 groups: Compoglass, Glass Ionomer Cement, Z250 and Control. Each group contained 15 paired teeth. Class-II preparation was performed on one tooth of each pair, and restored. Teeth were placed in demineralization solution for three weeks. The proximal surface of un-restored teeth were sectioned longitudinally (140-160µm) and analyzed microradiographically. Chi-square showed significant differences among all groups, (df = 3 = 10.01, p = 0.018). Pair-wise comparisons showed that: Compoglass had less demineralization than the control (df = 1 = 4.8, p = 0.033) and was no different from GIC (df = 1 = 0.2, p = 0.5). Copmoglass had less demineralization than Z250, however, not significant (df = 1 = 3.4, p = 0.07). There were significant differences between GIC and Z250 (df = 1 = 5.0, p = 0.03) and the control (df = 1 = 6.6, p = 0.013). Z250 was no different from the control (df = 1 = 0.14, p = 0.5). The study demonstrates the ability of Compoglass to intervene before a carious lesion occurs when placed in an adjacent class-II restoration. |
