Description
The purpose of this study was to evaluate whether a Gallium Nitride (GaN) -based violet laser diode (VLM500) could be used as a light source for light-cured dental resins. Three experimental unfilled resins containing different photoinitiators (camphorquinone, CQ; phenyl propanedione, PPD; or mono acylphosphineoxide, MAPO) were evaluated. These resins were light-cured with a VLM500 laser diode, and their ultimate micro-tensile strengths (ىTS) were compared to those cured with three different LED light sources (Curenos, G-Light Primanormal mode and G-Light Prima-PL mode). The VLM500 produced high ىTS values in all three resins, and we concluded that this violet laser diode can be used as a light source for light-cured dental resin materials.
