title: Three-Year Clinical Evaluation of Class I Restorations in Posterior Teeth. Effects of Two Adhesive Systems.
abstract: This longitudinal study evaluated the clinical performance of 97 direct class I resin composite restorations after 3 years. The restorations were performed using 2 types of adhesive systems: (1) Adper™ Single Bond Plus (SB) (3M ESPE, 3mespe.com), which is a two-step etch-and-rinse system, and (2) Adper Scotchbond™ SE (SE) (3M ESPE), which is a two-step self-etching system. Two calibrated examiners evaluated the restorations using modified US Public Health Service criteria. The materials were applied following the manufacturer's instructions, and 15 patients received at least one of the two adhesive systems. The restorations were evaluated 7 days after placement (baseline) and again after 3 years. Statistical analysis was performed using a proportion t-test at a significance level of 5% (P < .05). At baseline, all restorations received an Alpha score for the variable marginal discoloration and marginal integrity. After 3 years, marginal discoloration received an Alpha score for 53.19% of the restorations performed with SB and 52.08% with SE. Marginal integrity was rated as Alpha for 65.96% and 68.75% of the restorations with SB and SE systems, respectively. The remaining restorations received Bravo scores for all variables. Eight restored teeth presented postoperative sensitivity at baseline (5 SB; 3 SE), but no sensitivity was found after 3 years. No secondary caries was verified. No statistically significant differences were observed between the teeth restored with the SB and SE systems for marginal discoloration (P = .7880) and marginal integrity (P = .8132) after 3 years. Direct class I resin composite restorations performed with a two-step etch-and-rinse and a two-step self-etching adhesive system demonstrated satisfactory clinical performance after 3 years.
