Thirty-Six Months Clinical Evaluation of 10%DMSO Primer in Carious-Cervical-Lesions
Objectives: This randomized clinical trial assessed the impact of applying 10% DMSO/H2O before etch and rinse adhesive on the durability of carious cervical lesions (CCL) restorations using FDI criteria for restoration evaluation.
Methods: The inclusion requirements were met by Seventy-four CCLs. Cavities were treated with (37% H3POO4) for 15 seconds before rinsing them for another 15 seconds before bonding. Under rubber-dam isolation. Both groups received bonding with Single-Bond2 (3M-ESPE) and restoration with Z350XT nanohybrid-composite (3M-ESPE) under rubber-dam isolation. In intervention group, solution of 10% DMSO/H2O was applied for 60-seconds, followed by air-drying after etching and before adhesive application. Assessment of the restorations was conducted at baseline, 12-months, 24-months, and 36-months using the FDI-criteria for evaluation. For statistical analyses, categorical data was described as frequency and percentage, intergroup comparisons between interventions were performed using Chi-Square test with statistical significance level set at (P ≤ 0.05), intragroup comparison within each intervention was performed using the Cochran’s Q test with statistical significance level set at (P ≤ 0.0083) after Bonferroni correction.
Results: In the current study, intergroup comparison between both groups at baseline and after 12 months showed no statistically significant differences for all tested outcomes (P>0.05), except for postoperative sensitivity at baseline, where there was statistically significant difference (P<0.05) favoring DSMO. However, after 24 and 30 months, intergroup comparisons revealed statistically significant difference for all tested outcomes (P<0.05) favoring DSMO. Intragroup comparison within control revealed statistically significant deterioration through time (P < 0.0083), while within DSMO there was no statistically significant change through time (P > 0.0083).
Conclusions: 10%DMSO Primer improved the durability of etch and rinse adhesives, which were used to bond composite restorations to CCLs. Longer follow-up should be evaluated in the future.
