Paper Abstract

Since the development of the ruby laser in the early 1960's there has been interest in the area of lasers in dentistry. This interest centered around both hard and soft tissue applications. In the 1970's dentists began using an ultra-violet (UV) light source in the photopolymerization of composite dental materials. Because of the concern regarding the UV light in the mouth a composite resin which activated at 460 nm light was developed. It is intriguing to consider the laser as a better curing light by virtue of the fact that this light is monochromatic, coherent and well collumated. The question this paper has attempted to answer is whether or not laser energy is of benefit in the curing of dental composite resins. A Helium Cadmium (442nm) and Argon Laser (488 nm) were used and compared with a typical dental white light curing unit. Both micro and small particle-sized composites were examined. The results suggest that the lasers tested are not of any great benefit over conventional methods.
