许多学者发现斑釉里氟的含量高,但是氟在牙釉质含量高时,是否一定出现氟中毒这个向题未得到定论。Mortenson等在家畜的研究中发现随着前牙氟中毒严重程度的增加,氟含量有增高的趋势,而釉质厚度却减少。Ruzicka等通过动物实验发现服用不同 Many scholars have found that there is a high content of fluorine in the spot glaze. However, the question of whether fluorosis should occur when fluoride is high in enamel has not been conclusive. Mortenson et al. Found in livestock studies that as the severity of fluorosis in the anterior teeth increases, the fluoride content tends to increase, while enamel thickness decreases. Ruzicka et al. Found that taking different animals through experiments
