Introduction:Irradiation of human dental enamel with laser energy at particular wavelengths in the visible and infrared regions result in greater resistance to acid and cariogenic attacks. The aim of the present study was to investigate the effectiveness of four commonly available laser wavelengths,KTP, Nd: YAG, Diode, CO2 in terms of the LAF protective effect to an erosive challenge. Materials and Methods: 40 sound human premolar teeth were used. The lingual and buccal surfaces of the teeth were sectioned into slabs using a diamond saw. The baseline Vicker's hardness number (VHN) of each surface was determined. 1.23% NaF gel was then applied to these slabs and they were divided into Group I - Control group. Group II - KTP Group III - Nd:YAG Group IV - Diode Group V - CO2. The Vicker's hardness number (VHN) of each surface was again determined after the fluoride and laser treatment. Results: Group II and Group III, which are KTP and Nd:YAG respectively showed significantly small amount of change as compared to the other groups. Conclusion: In order of merit least reduction in hardness after acid challenge was shown by Nd:YAG followed by KTP, CO2 and diode laser.
