This study of the development and mineralization pattern of the enameloid of the teeth of the fish (Hoplognathus faciatus) demonstrated the following :
The enameloid intake of 45Ca in the early stages of its formation started near the dentino-enameloid junction. This was followed by calcification of the middle and superficial layers of the enameloid. This was verified by the historadiographs.
The combined scanning image of Ca, P and Mg obtained with the XMA also showed excellent agreement with the historadiographic images.
The individual XMA images for Ca and P each resembled the mixed image for Ca, P and Mg.
The image for Mg alone, however, showed a density much less than any of the others indicating its much lower concentration.
