Clinical Evaluation of Posterior Direct Restoration in Adolescents

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.
