Abstract

Dental hypersensitivity is a commonly seen complaint in dental clinics. It is caused by thermal, chemical or mechanical stimulation of exposed dentine, and may be so severe that it affects mastication. Conservative treatments using topically applied medicines have not achieved good results. Over a period of more than one year, 105 patients suffering from dental hypersensitivity were treated using the Nd-YAG laser. Whilst the effectiveness of this treatment was rated as 90%, the incidence of associated thermal damage to dental pulp was not studied. Other experimental investigations have shown that the thermal effect of the laser can cause damage to dental pulp (1).

In this study, histopathological changes to molars of rats and humans have been investigated following irradiation with the Nd-YAG laser. The irradiation dose used was based upon data from a study on changes of pulp after laser irradiation for caries prevention in our hospital (2, 3).
