3 groups of 45 patients will receive class II restorations by using calcium and phosphate releasing hybrid restorative material (Activa Presto), fluoride releasing hybrid restorative material (Giomer), and conventional nanofilled resin composite. Then these restorations evaluated at 24 hours after placement, 1 month, 3 months, 6 months and 12 months according the modified USPHS criteria in terms of fracture, marginal adaptation, retention, anatomic form, marginal discoloration, surface texture, and color match.
Esthetic and mechanical evaluation of calcium and phosphate releasing hybrid restorative material and fluoride releasing hybrid restorative material versus the conventional nanofilled resin composite in proximal carious lesions over 1 year follow-up according to the USPHS criteria.
