To investigate the effect of diode laser application and two commercial remineralizing agents on the remineralization and surface microhardness of white spot enamel lesions.
Sixty specimens were prepared then equally divided into six groups (n=10/group), according to the diode laser and the two commercial remineralizing agents applied to demineralized enamel surfaces (APF gel and sodium fluoride NaF mousse) with or without diode Laser application as follows; Group A; control, Group B; diode Laser application, Group C; APF gel application, Group D; NaF mousse application, Group E; APF gel application + diode Laser, Group F; NaF mousse application+ diode Laser. Then the teeth were investigated for their Ca, P & F ions content and surface microhardness. One-way ANOVA followed by Tukey's (HSD) post hoc test were used for statistical analysis.
Ca ion wt% showed no statistically significant difference between tested groups, with the highest mean value recorded with Group C. P ion wt%, showed a statistically significant difference between Groups A and C, and the highest mean value was recorded for Group A. The highest F ion wt% was recorded for Group C, while the lowest was recorded for both A and B groups. The highest significant microhardness mean values was recorded for Group E, while the lowest was recorded for Group A.
Diode Laser treatment of the demineralized enamel surface had a positive influence on the chemistry and surface microhardness and it may represent a promising adjunct for enamel surface remineralization.

研究二极管激光应用以及两种市售再矿化剂对白斑釉质病变再矿化及表面显微硬度的影响。
制备60个样本，然后根据应用于脱矿釉质表面的二极管激光和两种市售再矿化剂（含氟磷酸凝胶和氟化钠泡沫）是否应用二极管激光，将其平均分为六组（每组n = 10），如下所示：A组为对照组；B组为应用二极管激光；C组为应用含氟磷酸凝胶；D组为应用氟化钠泡沫；E组为应用含氟磷酸凝胶 + 二极管激光；F组为应用氟化钠泡沫 + 二极管激光。然后检测牙齿的钙、磷和氟离子含量以及表面显微硬度。采用单因素方差分析，随后进行Tukey's（HSD）事后检验进行统计分析。
钙离子重量百分比在各测试组之间无统计学显著差异，C组记录的平均值最高。磷离子重量百分比在A组和C组之间存在统计学显著差异，A组记录的平均值最高。C组记录的氟离子重量百分比最高，而A组和B组记录的最低。E组记录的显微硬度平均值最高，而A组记录的最低。
二极管激光治疗脱矿釉质表面对化学性质和表面显微硬度有积极影响，可能是釉质表面再矿化的一种有前景的辅助方法。二极管激光应用、化学分析、表面显微硬度、再矿化剂白斑病变。
