DONATO, Lúcio Flávio Azevedo et al. Evaluate the depth of two composites' cure with different filler particles sizes. Odontol. Clín.-Cient. (Online) [online]. 2011, vol.10, n.3, pp. 277-280. ISSN 1677-3888.

This in vitro study aimed to evaluate the depth of two composites' cure with different filler particles sizes. Two micro-hybrid composites (Opallis FGM) and Charisma (Heraeus Kulzer)] and a nanofiller one Z350 (3M ESPE) were selected with A3 shade. Specimens with thicknesses of 2, 3 and 4 mm were made (n = 5) using the light emitting diode LED device (Radii SDI). After 24 h storage of specimens in containers free of light, hardness readings on the top and bottom surfaces were executed. Data were subjected to two-way ANOVA and Tukey tests (p = 0.05). There were differences between the composites, among the depths, as well as in the interaction of both factors. Z350 composite resin showed higher values than other materials in the most experimental conditions. The nanofiller material showed higher polymerization depth than those microhybrid ones.
