Abstract:

The clinical properties of light-cured composite resins are significantly influenced by the illumination intensityof the light source and the curing time. Two experiments （Cure Depth Test and Flexural Strength Test） were designed in the Dental Materials Course to help students understand how the illumination intensity and curing time influence the cure depth and flexural strength of light-cured composite resin. Experiments were carried out among stomatology students （Eight-year program）. A postclass questionnaire was designed based on the content of experiments and showed good teaching effects of the experiments.

Key words: Light-cured composite resins, Illumination intensity, Cure depth, Flexural strength
