The efficacy of carbon dioxide (CO) laser irradiation combined with fluoride in inhibiting enamel demineralization has been demonstrated by several laboratory investigations. However, there are very few reports about the or caries preventive effect of CO laser combined with topical fluoride on dental enamel. Hence, an study was designed and carried out to assess inhibition of mineral loss from human tooth enamel by CO laser and 1.23% acidulated phosphate fluoride (APF).
Impressions of upper and lower arch of the volunteers were made in alginate impression material. Study models were poured, duplicated, and duly labeled. On the working model, appliances were fabricated in acrylic resin to fit the upper dental arch of the volunteers. Four enamel slabs (one from each group) were fitted on the palatal surface of the appliance as close as possible to posterior teeth. Surfaces of slabs were kept below the outer surface of acrylic. The analysis was done using SPSS version 15 (SPSS Inc., Chicago, IL, USA) Windows software program.
Statistically significant increase in inhibition of mineral loss of enamel slabs when treated individually or in a combination of low power CO laser and 1.23% APF solution. The application of 1.23% APF solution after low power CO laser treatment showed maximum inhibition of mineral loss.
The combined use of this specific laser treatment plus fluoride was more successful than either laser treatment or fluoride alone in the inhibition of mineral loss in the mouth. The results of this study also suggest that the combination of low power laser treatment with fluoride therapy may be effective as a caries inhibition treatment.
多项实验室研究已证实二氧化碳（CO）激光照射联合氟化物在抑制牙釉质脱矿方面的功效。然而，关于CO激光联合局部氟化物对牙釉质的防龋效果的报道却非常少。因此，设计并开展了一项研究，以评估CO激光和1.23%的酸性磷酸氟（APF）对人牙釉质矿物质流失的抑制作用。
用藻酸盐印模材料制取志愿者上下牙弓的印模。灌注研究模型，复制并妥善标记。在工作模型上，用丙烯酸树脂制作适合志愿者上牙弓的矫治器。将四块牙釉质片（每组一块）尽可能靠近后牙安装在矫治器的腭侧表面。牙釉质片的表面保持在丙烯酸树脂外表面以下。使用SPSS 15版（美国伊利诺伊州芝加哥市SPSS公司）Windows软件程序进行分析。
单独使用或低功率CO激光与1.23% APF溶液联合使用时，牙釉质片矿物质流失的抑制有统计学意义的增加。低功率CO激光治疗后应用1.23% APF溶液显示出对矿物质流失的最大抑制作用。
在抑制口腔内矿物质流失方面，这种特定激光治疗加氟化物的联合使用比单独的激光治疗或氟化物更成功。本研究结果还表明，低功率激光治疗与氟化物疗法联合使用可能作为一种防龋治疗有效。
