...K. Sato Variations in acid dissolution and histological appearance of heated human tooth enamel due to temperature (100–600 °C) have been studied by means of chemical analyses, polarizing microscopy and scanning electron microscopy. The amount of dissolved Ca and the lesion depth obtained from...

... the more intimately associated FHA was found to affect the rate of acid dissolution of HA and its level of formation and the reduction in acid dissolution rate of HA were both found to be linearly related to the logarithm of the ionic fluoride level in the treatment solution following 1 min. pretreatment...
