The dental development of children aged seven to fourteen years in Bang Chan, Thailand, is described. Two hundred and forty children, 125 boys and 115 girls, were examined.

The median age of eruption is given for each type of permanent tooth for boys and girls. As noted in other areas, the median age of eruption for each permanent tooth was less for girls than for boys. Between ages eight and thirteen, girls in Bang Chan had more permanent teeth than did boys. At age fourteen, all children had all permanent teeth except the third molars, and 6 of those examined in age groups eleven to thirteen had one or two of the third molars.

Age of eruption of individual permanent teeth and total number of permanent teeth present at a given age in each sex were compared with corresponding data available for children in other parts of the world. No marked or consistent differences in dental development were noted between children in Bang Chan and elsewhere.
