Abstract
Choosing a total of 861 primary and junior high school children in Nagoya, 435 male and 426 female, the authors divided them by family occupation and studied the number of permanent teeth each child had, his height and, in the case of a girl, whether she is having the menses or not, in an attempt to find occupational characteristics, if any, in these respects, and also to learn if there is any correlation among these three factors-dental growth height and physical maturity. They also studied the rate of dental caries occurrence in each occupational group.
The survey, however, produced no results suggesting that the nature of a child's family occupation has any particular effect on his dental growth, height, physical maturity or vulnerability to dental caries.
