In vitro temperature change at the dentin/pulpal interface by using conventional visible light versus argon laser

The argon laser has been promoted as a competing technology to multi‐wavelength visible light as a curing source for dental restorative resins. However, the comparative thermal risk to the pulp between these two sources of light energy requires determination. The objective of this study is to compare the temperature induced at the dentin‐pulpal interface between the argon laser and visible light curing unit at a variety of exposure regimens and conditions.
