One operator will place all restorations under rubber-dam isolation. The patients will receive restorations with both materials, randomly after shade selection (The shade of single shade universal resin composite Omnichroma will be taken before and after placement into the cavity). During the referred period, only the two composites in study will be placed in posterior teeth in the dental office. The various materials' application procedure will be applied according to manufacturer's instructions.
This study is aimed to evaluate the clinical performance of new One-shade universal composite resin as posterior restoration using US Public Health Service USPSH criteria for color match, marginal adaptation, surface texture, retention, recurrent caries and others after 1, 3, 6 and 9 months.
