Structural relationships in orthophosphate (PO4)3-, carbonate (CO3)2-, and hydroxyl (OH)- groups were studied in 2 teeth with grave fluorosis manifestations, removed for orthodontic indications, by infrared spectroscopy. Two intact teeth were examined for control. The findings evidence ar elevated protein level in fluorosis-involved dental enamel and impaired enamel microstructure; this may be explained by specific features of fluorosis clinical manifestation and by increased enamel permeability in grave fluorosis.
采用红外光谱法，对2颗因正畸需要拔除的、有严重氟斑牙表现的牙齿中的正磷酸盐（PO4）3-、碳酸盐（CO3）2-和羟基（OH）基团的结构关系进行了研究。选取2颗完整牙齿作为对照。研究结果表明，氟斑牙受累牙釉质中的蛋白质水平升高，釉质微观结构受损；这可能是由氟斑牙临床表现的特殊特征以及严重氟斑牙中釉质渗透性增加所解释的。
