Effects of an argon laser on the crystalline properties and rate of dissolution in acid of tooth enamel in the presence of sodium fluoride.
Upon exposure to laser radiation, enamel powder mixed with NaF underwent an increase in crystallite size and/or perfection with a significant uptake of fluoride. Incisor teeth lased in the presence of NaF released significantly less calcium and phosphorus into sodium acetate (pH 4.0) compared with unlased controls, suggesting a possible role for the laser in caries prevention.
