Abstract

The use of the Nd:YAG laser on the vital tooth is not without problems, since neither the dental enamel nor the healthy dentin have an absorption maximum at the range of 1064 nm wavelength. An unhindered transmission of radiation may cause a reversible or irreversible damage of the dental pulp. To stay within these physical limits it can be helpful to apply an initiator gel to the tooth surface which will absorb the laser light at the surface of the tooth. The effect of an initiator gel on the temperature change in the dental pulp chamber during laser treatment of a dentin cavity was studied in vitro. The temperature changes were recorded with a thermistor. The results shows a significant difference within the first 20 seconds of laser treatment between the group with initiator gel and the one without.
