  • Method of preventing tooth decay by laser beam irradiation and chemical treatment
    Patent number: 4877401
    Abstract: A method for preventing tooth decay comprising: (1) laser irradiation of the tooth's surface with a carbon dioxide laser (wavelength=10.6 microns) at 20 to 50 watts for 1 to 400 seconds, and (2) subsequent chemical treatment of the tooth with a chemical agent such as ethane-1-hydroxy-1, 1-diphosphonic acid at concentrations greater than about 0.00001 molar. The resulting tooth has a reduced dissolution rate in acid and increased resistivity to cavities.
