Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In accordance with a split-mouth design, 50 patients will be received at least one pair of restorations, restored with a nanofill resin composite (Filtek Ultimate \[FU\]) and with a bulk fill resin composite (Tetric EvoCeram Bulk Fill \[TB\]). Each restorative resin will be used with its respective adhesive system according to the manufacturers' instructions. A total of 104 class II restorations will be placed by two operators. The restorations will be blindly evaluated by two examiners at baseline and at 1-, 2-, 3-, 4-, 5-, 6-, 7- and 8- year using modified US Public Health Service Ryge criteria. The comparison of the two restorative materials for each category will be performed with the chi-square test (a=0.05). The baseline scores will be compared with those at the recall visits using the Cochran Q-test.
