title: [Age determination by radiographic feature of thyroid cartilage in female Han population].
abstract: OBJECTIVE
  To seek a method of age determination.
  
  
  METHODS
  This sample consists of 69 female Chinese han individuals whose ages been known. Five 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 female thyroid cartilage is 1.969 and the multiple correctation coefficient is 0.984.
  
  
  CONCLUSIONS
  The observation proved that age determination by radiographic feature of thyroid cartilage can be used for female Chinese han population from 18 to 60 years old.
