The aim of this study was to assess the caries-preventive potential of various carbon dioxide laser conditions and to explore the effect of the number of laser pulses used. The authors irradiated unerupted human molars at two wavelengths—10.6 or 9.6 micrometers—and at 1, 5, 25 or 100 pulses. All teeth were then subjected to pH cycling simulating the conditions for caries progression. Pulsed CO₂ laser-preventive treatment inhibited carieslike lesion progression by up to 87 percent. This effect was dependent on the number of pulses used, but there was no correlation between caries resistance and enamel surface morphological changes.
