One hundred thirty-six male naval personnel, ages 17 to 23, with a history of no decay upon entering military service were observed for a 1 year period. During this time 76 55.9 developed one or more carious lesions. The relationship of caries development during this period exposure to fluorides in drinking water was studied. Of the 136 men, 112 82.4 had some exposure to either natural or controlled fluorides prior to entering military service 24 17.6 had no known exposure. A chi-square analysis of the data indicated that no significant correlation could be established between caries experience and fluoride exposure for these subjects. Among 76 individuals exposed to natural fluoride, 47 61.8 developed lesions and of the 27 individuals exposed to controlled fluoride, 13 48.1 developed lesions. Of the 24 individuals not exposed to fluoride, 11 45.8 developed lesions. Five out of nine individuals intermittently exposed to both natural and controlled fluorides developed lesions. Since some individuals who remained caries-free were not known to have been exposed to fluoride, other factors regarding caries resistance must be considered. Author
