Abstract
The purpose of this study was to compare the diametral tensile strength values of several pit and tissue sealants following their polymerization by an argon laser and a conventional visible light source. It was noted that these values for all the laser polymerized products were equal to or statistically superior to values achieved by conventional visible light curing. Based upon the results of this study, it was concluded that an argon laser could be used to satisfactorily polymerize dental pit and fissure sealants and that this could be done with a marked reduction in polymerization time.
