Abstract:

Objectives This study evaluated the depth of cure of Surefil SDR Flow Dentsply, Grandio Flow VOCO and Venus Bulk Fill Heraeus and a conventional flowable composite, Revolution Kerr using bottommaximum Knoop Hardness Number KHN ratios and the scrape technique ISO 4049. Methods Specimens were polymerized Bluephase G2, Ivoclar for 20 and 40 seconds at 0-mm distance. For KHN, five specimens were polymerized per flowable composite shades A2, A3, and Universal for Venus in 2-, 3-, 4-, 5-, and 6-mm-thick by 8-mm-diameter plastic molds. All specimens were stored for 24- hours at 37C in 95 humidity. KHN were determined from three measurements each shade per thickness using a hardness tester Leco.
