Abstract

The study was aimed at evaluating the depth of cure and of a composite resin that was photo-activated using different methods.

A composite curing test fixture was filled with composite resin and photo-activation was performed using three methods: (1) Intermittent method (2) Continuous method (3) Exponential method. Depth of cure was measured at the unexposed bottom surface of the specimen using vicat polymer softening apparatus.

The data was analyzed using Kruskal-Wallis test. Results showed that the depth of cure was highest with the intermittent method, followed by continuous method and the exponential method.
