Randomized clinical trial of class II restoration in permanent teeth comparing ART with composite resin after 12 months

摘要

Objective This study evaluated the effectiveness of class II restorations, in permanent teeth, through the ART technique in comparison to composite resin. Materials and methods Participants (154), aged 8 to 19 years, with good general health, with class II cavities in permanent teeth, and without pulp involvement and tooth pain were included in this parallel and randomized clinical trial. The Ethics Committee approval number was CAAE: 24012913.0.1001.5417. Seventy-seven restorations were made with each restorative material (Equia Fil-GC Corporation and Z350-3M). Evaluations occurred at 6 and 12 months by the criteria of ART and the USPHS modified. Data were analyzed by Mann-Whitney, chi-square, Fisher's exact, chi-square tests with linear trend and logistic regression by enter method (p 0.050). Survival rates for restorations, regardless of the evaluation criteria used, are the same as the success rates, with the exception of ART restorations at 12 months of follow-up (94.8%). Conclusion No differences in the success rates of class II restorations of ART compared to resin composite, in permanent teeth, were observed after 12 months. Clinic significant HVGIC can safely be used to restore proximal cavities in permanent teeth up to 12 months.
