Abstract
In the previous paper, I reported that fluoride distribution patterns in the cementum of 27 different teeth from a single male subject aged 54 years were roughly consistent. These results suggested that each subject would have its own characteristic fluoride distribution pattern influenced by personal history in relation to the fluoride environment.
In the present work therefore, I studied fluoride distribution patterns in the apical cemeneum of 8 different tooth types (21, 23, 24, 26, 31, 33, 34, 36) from 5 male subjects aged 30-70 years, using the abrasive micro-sampling technique.
The results were as follows:
1) Although distribution patterns of fluoride in the cementum varied with subjects, those obtained rom the same subject were roughly similar. I concluded that each subject had its own characteristic fluoride distribution pattern in the cementum.
2) The subject itself was more significantly related to the fluoride content than the tooth type or the upper or lower jaw.
