Depth of Cure of New Flowable Composite Resins

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 bottom/maximum 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).
