Groups (for each composite) n = 240Polishing protocolsChallenges (subgroups)

CWP Positive controlWithout polish—Specimens were not subjected to finishing/polishing procedures after light-curing under polyethylene strip n = 20Artificial saliva n = 10 or HCl 5% n = 10
CW Negative controlWith wear—The top surfaces of the specimens were ground with a conical diamond tip 3195 FF, with air/water cooling, for 10 s, obtaining 0.3 mm of wear n = 20
WPC Wear + polish with Cosmedent KitWear with FG 3195 FF + polishing with medium-grained siliconized cups (blue color), extra-fine grain (pink color), and spiral-shaped diamond wheel for high brilliance, diameter 1/2" (pink color) n = 20
WPB Wear + surface sealant applicattion BisCover LVWear with FG 3195 FF + sealant BisCover LV n = 20
