Abstract
We analyzed 121 age estimation clients who had visited oral medicine clinic, Chonbuk National University Hospital, from January 2000 to December 2007 to evaluate its characters in Jeonllabuk-do. The obtained results were as follows;
1. There was distinct difference in sex distribution(Male : 58.7%, Female : 41.3%) and more than half percent(55.4%) was over 50¡¯s.
2. The difference between registered and alleged age was the most in more than 5 years, and most of them were over 50¡¯s.
3. There were more clients who wanted to increase their age than to decrease and was no prominent difference in sex. Age estimation clients who wanted to decrease their age were predominant under 10 years old and in 20¡¯ s, and those wanted to increase were predominant in 10¡¯ s and over 30¡¯s.
4. The most reasons to correct age were related to welfare benefit. The purpose of age estimation was different according to each age groups; welfare benefit was the most over 50¡¯s, occupation in 40¡¯s and 50¡¯s, friendship in 30¡¯s and 40¡¯s, sibling-related in 50¡¯s, employment in 10¡¯s and 20¡¯s.
5. Age was estimated by the attrition of permanent tooth and pulp/tooth ratio from 20 years, root apex closure for 10¡¯s and calcification of permanent tooth under 10 years old, In cases that were difficult to estimate by use of the attrition of permanent tooth and pulp/tooth ratio, age was estimated by missing time of permanent tooth and the change of mandibular angle with age.
6. The estimated ages were close to alleged age in 77.7% of clients but the rest(22.3%) was close to registered age.
