[Age determination by radiographic feature of thyroid cartilage in male Chinese Han popullation].
OBJECTIVE
To seek a exact method of age determination.


METHODS
This sample consists of 73 male Chinese han individuals whose ages have been known. Eight positions were selected from their radiograms which have been divided into three or six grade and then set up a mathematical model to deduce age by multiple linear regression analysis.


RESULTS
The standard deviation of male thyroid cartilage is 1.854 and the multiple correctation coefficient is 0.9971.


CONCLUSIONS
The observation proved that age determination by radiographic feature of thyroid cartiage may be suitable for male Chinese han population from 13 to 67 years old.
