Aim: The purpose of this study was to evaluate the clinical performance of Ketac Nano (Ketac N100), RMGIC (Fuji Filling LC), and Giomer (Beautifil® II) in noncarious cervical lesions (NCCLs). Materials and Methods: One operator restored 120 NCCLs in 20 subjects, with at least two lesions restored with one of the restorative materials: RMGIC (control group), Giomer and Ketac Nano (experimental groups). Two observers evaluated retention, marginal discoloration, marginal adaptation, color match, surface roughness, and postoperative sensitivity using modified USPHS criteria at baseline, 6, and 12 months. Study Design: Double-blinded randomized clinical trial (RCT). Statistical Analysis: Kruskal–Wallis test, Mann–Whitney U-test, Wilcoxon matched-pairs test. Results: There was statistically significant difference observed between Giomer, Ketac Nano and RMGIC after 12 months (P < 0.05). There was a significant decrease in retention rates for Giomer (P = 0.0050), increased marginal discoloration and color mismatch for Ketac Nano (P = 0.0025, P = 0.0053), increased surface roughness and color mismatch with RMGIC (P = 0.0022, P = 0.0077) from baseline to 12 months. Conclusion: Within the limitations of this RCT of 12 months, Ketac Nano and RMGIC restorations were better retained in NCCLs while superior color match and surface finish were observed with Giomer restorations.
