Abstract: 205 pubic bones of Chinese male between 17 and 40 years of age were observed. The criteria for scoring the age changes of eight morphological features on the pubic symphysis were established. With these criteria, authors scored 205 samples. By employing multiple regression analysis and quantification theory model 1, the multiple regression equations were computed and compared w?th Hanihara's. Statistical analysis and the blindfold test trom 50 other samples show that it is more reliable that Hanihara's and has certain values for practical use.

Key words: Pubic symphysis; Age Changes; Age estimation; Moltiple analysis
