The experimental period was from twenty-two to thirty-five days. The rats were randomly placed into seven groups and were fed Purina Laboratory chow and tap water, to which had been added either none, 50, or 100 ppm fluoride. At the conclusion of the study the first and second maxillary and mandibular molars were extracted and the apical one millimeter of each root was collected for analysis. The samples were ashed and then dissolved in l ml of 0.5 M HC10 [subscript 4] and 4 ml of 0.5 M Na Citrate. The fluoride concentration of the samples was obtained by use of the Ionalyzer (Orion Research, Inc., Mode1 401) with its component specific fluoride ion activity electrode and essential reference electrode and standardizing solutions. The results were statistically significant (p <.00l) and the mean fluoride values ranged from 500 ppm to 2,100 ppm for the controls and from 3,900 ppm to 6,500 ppm for the experimental rats ingesting 100 ppm fluoride in their drinking water. The experimental design and significance of the results are discussed.

This study used LA-ICP-MS on a documented sample of modern teeth to sample from a continuous line across the cementum increments thus creating a temporal line graph of the elemental composition against distance. The knowledge of cementum was extended through (1) a more complete elemental composition analysis and (2) the relation of element distribution to the ultrastructure structure throughout the life of a tooth. This study was exploratory and demonstrated that lead, zinc, mercury, and barium follow the same general line of changes, and most likely represent changes in health and exposure to these metals in the general environment. Copper, manganese and vanadium varied very little. Technological limitations prevented the examination of element levels in any one annulation.
