The analysis of the disinfection effect of Nd:YAG laser radiation was investigated for patients with high
concentration of Streptococcus mutans in saliva (positive result in Saliva-check mutans test). For the interaction the
Nd:YAG laser system generated separate switchable wavelengths with the maximum output energies 1.1, 0.6, and
0.3 J for wavelength 1.06 μm, 1.32, μm and 1.44 μm, respectively, was used. Our study proved that after the laser
irradiation the Saliva-check test showed negative presence of Streptococcus mutans. The disinfection effect was
confirmed for all used radiation wavelength. For 1.44 μm this effect was reached with a smallest energy density.
