The purpose of this study was to obtain standard measurements of the tooth size,
Boston ratio, width and length of dental arch and basal arch, overbite and overjet of the
children who have normal dentition. The plaster cast of 41 children(21 boys and 20
girls) among the contestants in 1992 Healthy Dentition contest in Seoul were measured
and following results were obtained.
1. Means and standard deviations of the mesio-distal maximum width of the permanent
teeth, Bolton ratio, width and length of the dental arch and basal arch of the upper and
lower dentition and overbite and overjet of the children were obtained.
2. Mesio-distal width of the teeth, width and length of the dental arch and basal arch
of the upper and lower dentition of the boys were larger than those of the girls.
3. Bolton Overall ratio and overjet of the boys were larger than those of the girls and
Bolton Anterior ratio and overbite of the boys were smaller than those of the girls, but
no significant differences were noted between the boys and the girls(p>0.05).
4. In the comparision of the Healthy Dentition Contestants with Korean adults, all teeth
except lower first molar of the Contestants were larger than those of Korean adults. In
the comparision of the Healthy Dentition Contestants with Caucasians, all teeth except
upper central incisor and upper first molar of the Contestants were larger than those of
Caucasians.
