Compact Nd:YAG laser operating at 1.06, 1.32, and 1.44 μm for dental caries effective disinfection

摘要

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 maximum output energies 1.1, 0.6, and 0.3 J for wavelengths 1.06 μm, 1.32, μm and 1.44 μm, respectively, were used. Our study proved that after laser irradiation the Saliva-check test showed negative presence of Streptococcus mutans. The disinfection effect was confirmed for all the radiation wavelength used. For 1.44 μm this effect was produced with the smallest energy density.
