| Summary: | Introduction: This randomized clinical study aimed to evaluate the clinical performance of composite and compomer materials in primary molars over two years. Methods: Children aged five to six years with at least two carious proximal surface primary molars were screened for resin-hybrid composite (Kerr Herculite Classic) and compomer (Dyract XP and R&D Series Nova) restorations. The restorations were clinically evaluated after 3, 6, 9, 12, 15, 18, and 24 months using the modified United States Public Health Service criteria. Statistical analyses were performed using Chi-square, McNemar, z-tests, and Kaplan-Meier survival analysis. P<0.01 and P<0.05 values were considered statistically significant according to the test used. Results: The survival rates were 95.3% for Kerr Herculite Classic resin-based composite, 97.6% for Dyract XP, and 95.4% for R&D Series Nova compomer restorations with no statistically significant differences (P>0.05). No significant differences were observed between the three materials concerning retention, color matching, marginal discoloration, anatomic form, marginal integrity, secondary caries, and surface texture (P>0.05). No statistically significant differences were also found between the effects of the cavity type, the tooth position in the arch, the age of the patient, the restorative material, and the lining material on the survival rates of the teeth (P>0.05). Restoration loss was higher in males than females, and a statistically significant relationship was observed in terms of gender (P=0.017). Restoration loss in the first primary molars (8.3%) was greater than that in the second primary molars (6.7%) (P=0.041). Conclusion: Both composite and compomer restorations were clinically successful over two years. |
