Abstract Objective To evaluate the clinical performance of self versus light-cured universal adhesive in non-carious cervical lesions (NCCLs) after 18 months. Materials and methods Sixty-eight NCCLs in 28 patients were divided into two equal groups; G1: self-cured universal adhesive (Palfique,Tokuyama,Japan) and G2: light-cured universal adhesive (Single Bond Universal,3 M ESPE,USA). Nanohybrid resin composite (Z350XT, 3 M ESPE, USA) was used as a final restoration. Evaluation for fracture, loss of retention, marginal adaptation and discoloration were done after 1 week, 6,12, and 18 months using FDI criteria. Postoperative sensitivity was assessed after 1 week. Chi-Square and Mann-Whitney tests with statistical significance at (P ≤ 0.05) were used for intergroup comparison,while the intragroup one was performed using the Cochran’s Q and Friedman’s tests. Survival rate was analyzed using Kaplan-meier and Log-rank test. Results Both groups exhibited fracture and retention loss, however, there was statistically significant difference favoring the control group at 6 months (p = 0.0114,0.0016). For secondary outcomes, marginal adaptation and discoloration revealed no significant differences. For postoperative sensitivity, there was a significant difference favoring the control group (p = 0.0007, 0.0011). Palfique had 1.5 Relative-Risk (RR) after 6 months (95% CI 0.5659–4.2617; P = 0.3928) and 20% less risk of failure after 18 months (RR 0.8) (95% CI 0.4618–1.3858; P = 0.4260). Tested adhesives showed equal survival rate (P = 0.5685). Conclusions Both adhesives revealed similar clinical performance in restoring the NCCLs after 18 m, however, the early failure was more frequent in the self-cured universal adhesive. |
