Aim: The aim of this study was to assess the performance of moisture resistant, M-TEG-P containing universal adhesive (TMR-Aquabond0, YAMAKIN CO., Japan) in comparison to 10-MDP containing universal adhesive (Single Bond Universal Adhesive, 3M ESPE, USA) in geriatric patients with NCCLs. Materials and methods: 28 participants were enrolled in this study. NCCLs were restored using nano hybrid universal resin composites preceded with either Aquabond0 or Single bond universal adhesive. Restorations were assessed using the World Dental Federation (FDI) criteria at baseline (1 week), 6 and 12 months, measuring fractures and retention, marginal adaptation, marginal staining, post-operative sensitivity, and secondary caries. Categorical data was described as frequency and percentage, intergroup comparisons between interventions were performed using Chi-Squared test with statistical significance level set at (P ≤ 0.05), survival rate was analyzed using Kaplan-meier and Log-rank test. Results: No statistically significant difference between the two groups was found for all outcomes p>0.05. However, a statistically significant difference was found regarding survival analysis (p=0.034) where 10-MDP containing adhesive showed higher survival rate than M-TEG-P phosphate containing universal adhesive. Conclusion: Both universal adhesives revealed acceptable performance after 12 months of clinical service in NCCLs in geriatric patients. However, it should be noted that (Single Bond Universal, 3M ESPE, USA) showed a better survival rate.
