X-ray photoelectron Spectroscopy(XPS)and SEM were used in the study of Chemical and morphological changes of enamel surface immersed in demineralization or remineralization solutions containing various concentrations of fluoride ions,It was found that the addition of low concentration of fluorides to the demine ralization solutions could not effectively inhibit the dissolution of calcium and phosphorus,Only in the presence of exogenous calcium and phosphorus,demineralization of the enamel surface could be suppressed,and re mineralization takes place.High fluoride concentration can accelerate the remineralization process through the deposition of calcium fluoride and fluorapatite on the enamel surface,and thus enhance the acid-invulnerability of the enamel surface.

用光电子能谱(XPS)和扫描电镜(SEM)分析体外人牙釉质片经含不同浓度氟化物的脱矿液和再矿化液处理后釉质表面化学成分和形态学变化。结果发现,脱矿液中单独加入低浓度氟化物不能有效抑钙和磷溶解,在有外源性钙和磷存在时,才能获得再矿化而抑制钙和磷溶解。脱矿环境中有高浓度氟,通过局部沉积氟化钙而抑制酸与牙的反应。氟促进再矿化主要表现在加速钙的沉积,同时本身参与形成氟磷灰石,提高了牙齿的耐酸能力。

Objective: To study the effects of several remineralization solutions with different composition on the artificial demineralization lesions of bovine enamel and the mechanism of remineralization layer formation. Methods: 36 bovine teeth were selected and artificial carious lesions were formed with lactic acid gel. Then all specimens were divided into 4 groups which contained no fluoride, fluoride, fluoride calciulm phospate tin, and de ionic water separately, and the de ionic group was taken as control. The structure and composition of the sediments on the enamel surface were evaluated and detected by X ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). Histological change of enamel section was examined by polarized microscopy. Results: Compared with the control group, all the solutions had remineralization effects, especially the solutions containing trace elements. XPS showed that there were sediments formed on the surface of carious lesion, the compositions of the sediments were CaF\-2, HAP and non specifically absorbed fluoride (NSAF). Irregular, crystal deposits were also found under SEM on the enamel surface. The polarized microscopy results showed that the observed demineralization areas decreased after exposure to the solu tions. Conclusion: Solutions containing fluoride and trace elements were effective on remineralization. The possible mechanism is that CaF\-2 and NSAF, instead of FA formed in the remineralization layer. Moreover, the remineralization effects of the fluoride solutions containing trace elements are more outstanding than that without trace elements. The potential mechanism is the synergistic action of fluoride and trace elements.\;
