AB - Dental development is valuable for age estimation of children because of its low variability and less affection
by endocrine and nutritional status. Demirjian reported a new system of dental age assessment in 1973 and this
method has been used in many countries. The accuracy of Demirjian’s method in dental age estimation may be affected
by ethnic difference. For Korean population, the population study of Demirjian technique has not accomplished yet,
therefore, we investigate and analyze the validity of Demirjian’s method in Korean population.
The 155 orthopantomographys which consisted of 87 boys and 68 girls were randomly selected and the age range
was 5 to 16 years. The age of radiography was estimated according to criteria presented by Demirjian. Statistical analysis
was preformed between real age and estimated age.
In boys, there was no significant difference observed (p=0.171) between the real age and estimated age, however in
girls, significant difference was shown (p=0.022) in 95% confidence interval. In both groups, there was clear overestimation
tendency below 8.0 year, but over 8.0 year the difference pattern is atypical. The Pearson correlation coefficients
between real age and estimated age were 0.970, 0.964 in boys, girls, respectively and showed positive relationship.
The standards of dental maturation reported by Demirjian may not be applicable in Korean children especially in girls.
Establishment of new maturation scores and percentiles curves for Korean population with many samples is required
for more accurate age estimation.
