About

The present study aims to evaluate the performance of direct restorations with bulk fill resins in molars with great structural loss, with endodontic treatment. The behavior of class II restorations in 68 molars endodontically treated with bulk fill resin and incremental technique will be evaluated by means of a randomized clinical trial with a two-year follow-up. This project aims to evaluate the performance of this new restorative strategy that can greatly contribute to restorations of posterior teeth.

Full description

Sixty-eight endodontically treated molars were restored in 54 adolescents (10-18 years old, mean= 14.0 +- 2.4). Teeth were randomly assigned to the incremental filling technique (Filtek Z230/Vitremer, 3M-ESPE, n = 31) or high viscosity bulk fill technique (Filtek Bulk Fill Posterior, 3M-ESPE, n = 37). The restorations were clinically evaluated at baseline, 12 and 24 months by two independent raters using modified United States Public Health Service criteria. Data analysis included descriptive statistics, Mann-Whitney and Friedman non-parametric tests, and Generalized Estimating Equation (GEE) analysis.
