Abstract: Objective: To compare the clinical effects of direct filling with SDR resin and indirect repair of non-carious cervical lesion with Ceramage polymer ceramic inlays. Methods: 52 patients with bilateral symmetric non-carious cervical lesion in mandibular first premolar with wear index Ⅲ in the Department of Stomatology of our hospital were selected from September 2018 to August 2019. Each pair of the defects was randomly divided into group A and group B. The two groups were respectively filled with SDR resin and repaired with Ceramage polymer ceramic inlay. After 1 month, 3 months, and 12 months, the clinical effects of these two methods were evaluated by checking the defects of the filling body, the degree of edge coloration, the degree of edge tightness, and the tooth sensitivity after operation. Results: 12 months after filling, there was no loss or defect in the two restorations. The difference of marginal tightness between two restorations after 12 months of filling was not statistically significant (P>0.05), however, the difference of edge staining degree was statistically significant (P<0.05). The edge coloring degree of group B was lighter than group A. The sensitivity of two groups of teeth after 1 month of filling was statistically significant (P<0.05), in which the sensitivity of group B was lower than that of group A. Conclusion: Both Ceramage polymer ceramic inlay and SDR resin are ideal materials for repairing non-carious cervical lesion. The postoperative edge coloring process and postoperative sensitivity rate of Ceramage polymer ceramic inlays were better than those of SDR resin direct filling.
