The Photocurability of a New Bulk-Fill Composite Resin: X-TRAFIL

Abstract

Objective: To evaluate photocurability of a 4mm sample of a bulk-fill composite resin, X-traFil, using the Knoop hardness test after curing 10 seconds at a distance of 0 mm. Materials and Methods: X-traFil, Voco composite material was examined. Ten specimens were prepared in a delrin mold 8mm diameter 4mm long and polymerized at one end with the Mini light emitting diode (LED) light curing system (Aceton North America). The 4mm thick samples were subjected to three top and three bottom surface microhardness measurements utilizing the Knoop hardness tester (Leco, LM 300 AT, St Joseph, MI) under a load of 100 grams for 15 seconds. For each sample a bottom to top Knoop hardness surface ratio was determined and a value of at least 80 was used to indicate the acceptable depth of cure. Results: The bottom to top surface Knoop microhardness ratio mean was 79.40 1.5 . The bottom to top surface KHN hardness ratio reflecting the relative degree of cure showed an acceptable hardness (cure) at a depth of 4mm at 10 seconds for X-traFil.
