One-year clinical evaluation of SureFil packable composite

The purpose of this trial was to clinically evaluate SureFil high-density posterior composite for Class II restorations of permanent first and second molars. All teeth were restored in occlusion with the natural dentition. After cavity preparation, the enamel was etched for 15 seconds with 34% phosphoric acid. No liner/base material was used for the dentin. Two applications of Prime and Bond 2.1 were placed for adhesion to the exposed dentin and etched enamel. One coat of adhesive was cured for 10 seconds with a curing light, and one thin coat was spread with a gentle jet of air. The cavity was restored in 3-mm to 5-mm increments. Evaluation was assessed immediately after placement (baseline), and at 3 months, 6 months, 9 months, and 1 year for retention, leakage, marginal integrity, color stability, abrasive resistance, surface staining, surface texture, postoperative sensitivity, and secondary caries. The restorations were evaluated indirectly for wear using a modified USPHS and indirect cast comparison method. At baseline, 25 restorations were graded Alfa in all categories. At 3-, 6-, and 9-month recalls (N = 24), all restorations were graded Alfa in all categories. At the 1-year recall (N = 20), there were three Bravos for surface staining.
