• Chenges in the Acid Resistance in Laser Irradiated-Remineralized Enamel.

抄録

The aim of this study was to examine the change in acid resistance of lased-remineralized enamel. Sixty-six enamel slabs were prepared from thirty-three human premolars. These enamel slabs were demineralized artificially. They were irradiated with a Q-switch Nd-YAG laser and remineralized with two remineralizing solutions, one with and the other without fluoride. To evaluate acid resistance, the enamel slabs were subsequently immersed in 0.1M lactic acid solution (pH 4.5) while stirring (139r.p.m. ±12; Mean±S.D.), and dissolved Ca²⁺ was measured as a function of time from 15min to 180min.<BR>The results were as follows:<BR>1) Laser irradiation increased acid resistance of demineralized enamel during short periods (up to 60min).<BR>2) Remineralization without fluoride increased acid resistance of demintralized enamel during short periods (up to 60min) regardless of laser irradiation.<BR>3) Remineralization with fluoride increased acid resistance of demineralized enamel during long periods (up to 180min) regardless of laser irradiation.
