The author surveyed on the maxillary median diastema of 1,355 (male: 723, female:
632) 'H' and 'K' primary school children aged from 6 to 13,
The results were as follows:
1. The prevalence of the maxillary median diastema was 12.6% in male, 8.7% in
female and 10.8% in both sexes.
2. The prevalence of the maxillary median diastema showed the highest rate in 8
years old boys and girls, and it showed decreasing tendency according to increasing
age.
3. Mean value of ' Frenum Distance' was 5.9§® in male, 5.4§® in female and mean
value of 'Divergent Degree' was 1.8§® in male, 1.6§® in female.
