NCT06137989

Brief Summary

This study (a double-blinded, prospective, randomized clinical trial) aimed to evaluate 2-year clinical performance of dual- and light-cure bulk-fill resin composites in Class ӀӀ restorations. The null hypothesis tested in this study was that, there would be no difference in the 2-year clinical performance of all tested bulk-fill resin composites in Class II restorations. Forty patients were enrolled in the study. Each patient received three bulk-fill resin composites Class ӀӀ restorations. One dual-cure and two light-cure bulk-fill resin composites were used for Class ӀӀ restorations following manufacturer's instructions. A universal adhesive was used with all restorations. All restorations were clinically evaluated after 1 week (baseline), 6 months, 12 months, 18 months and finally after 24 months using the FDI World Dental Federation criteria.

Outcome Measures

Primary Outcomes (3)

  • Esthetic properties (FDI criteria)

    Including five parameters (surface luster, margin staining, surface staining, color match \& translucency, and esthetic anatomical form). Each parameter is exhibited by five scores (1, 2, 3, 4, 5), score 1 is the best outcome. Three scores for acceptable (1, 2, 3) and two scores for non-acceptable (4 for reparable and 5 for replacement).

    From baseline to 2-year follow-up

  • Functional properties (FDI criteria)

    Including five parameters (marginal adaptation, occlusal wear, proximal contact, radiographic examination, and fracture of material \& retention). Each parameter is exhibited by five scores (1, 2, 3, 4, 5), score 1 is the best outcome. Three scores for acceptable (1, 2, 3) and two scores for non-acceptable (4 for reparable and 5 for replacement).

    From baseline to 2-year follow-up

  • Biological properties (FDI criteria)

    Including three parameters (post-operative sensitivity, recurrence of caries, and tooth integrity). Each parameter is exhibited by five scores (1, 2, 3, 4, 5), score 1 is the best outcome. Three scores for acceptable (1, 2, 3) and two scores for non-acceptable (4 for reparable and 5 for replacement).
