Background: Dental composite resins are types of synthetic resins which are used in dentistry as restorative material or adhesives.The resin-modified glass ionomer cement is the most frequently used cement for the cementation of well-fitting porcelain-fused-to-metal (PFM) crowns. The present study was conducted to compare the efficacy of composite resin andresin-modified glass ionomer cement (RGIC) for class III restorations. Materials & Methods: The present study was conducted in the department of Endodontics. It included 40 patients with class III cavity of both genders. All the patients were divided into two study groups. Group I were of composite resin cement and group II were of resin-modified glass ionomer cement. Results: Each group had 20 number of patients. The mean value of anatomical shape in group I was 1.2 and in group II was 1.06, adaptation of margin was 1 in group I and 1.2 in group II, discoloration of margin was 1 in group I and 1.1 in group II and secondary caries was 1 in both groups. The difference was non- significant (P> 0.05). Conclusion: Both the restorativematerials found to be equally effective in class III restoration in primary anteriorteeth.Anatomical shape, adaptation of margin, discoloration of margin and secondary caries in both groups were almost of same intensity.
