| Outline of Final Research Achievements |
Recently, the dental loupe and headlights that are widely used in daily dental practice. In order to examine the influence of headlight exposure on harden the restorative composite resin, this study measured the depth of cure of composite after the exposure of dental headlight. The results indicated that 1) larger intensity of light tended deeper depth of cure, 2) enamel shade cured deeper than dentin shade, 3) dentin shade did not find the significant difference among products , 4) for enamel shade, translucency of composite increased the depth of cure, and 5) the light exposure through the orange filter did not cure the composite.
