The present study aimed to test the hypothesis that irradiation of dental enamel by a TEA carbon dioxide laser together with fluoride, can effectively inhibit caries-like progression in sound and demineralized enamel. Blocks of human sound and demineralized dental enamel were divided into 11 treatment groups. Eighty enamel blocks were partially demineralized in a 50 percent HAP/0.1 M lactic acid/carbopol solution. Samples were treated with/without laser and/or F according to the above groups. The blocks were then submitted to 5 days of pH cycling. Microradiography was performed on 100 micrometers thin sections to determine the relative mineral loss as (Delta) Z and the percentage of caries inhibition for the laser and F treated groups. Mean (Delta) Z values for groups I-X were, respectively: 1043; 683; 614; 2294; 1803; 1708; 1547; 1791; 1656;; and 1385. The percent caries inhibition for groups II, III, V-X was respectively: 35, 41; 49; 62; 42; 53 and 76 percent. The combination of this new TEA CO2 laser and F treatment produced a significant protective effect against lesion progression.
