-Abstract-
Developmental changes of dental arch width and length from 6.6 to 13.6 years of age
have been studied in twenty boys and thirteen girls in Korean school children.
A series of 8 dental casts obtained from each child was measured in the intercanine
width, intermolar width and arch length.
Afterwards, mean value and each standard deviation of each age group and each
gender were obtained, and corresponding graphs were drawn.
The finding of this study can be summarized as follows :
1.Maxillary intercanine widths increased until age of 13.5 in males and age of 12.5 in
females. On the other hand, mandibular intercanine widths increased until age of 11.5 in
males and age of 9.6 in females and after there were on changes.
2. Maxillary intermolar widths increased until age of 13.5 but increments reduce from
age of 12.5 in both sex. Mandibular intermolar widths increased until age of 13.5 in
males and age of 12.5 in females. Annual increments of maxillary intermolar width
greater than those of mandibular intercanine width in both sex.
3. Maxillary dental arch lengths increased until age of 10.6 in both sex, and after
decreased until age of 13.6. Mandibular dental arch lengths increased until age of 10.5 in
males and of 9.6 in females, and after decreased until age of 13.6.
4. Developmental changes of dental arch width and length showed individual variation.
