title: [Study on reference value of healthy teeth mobility of youth].
abstract: OBJECTIVE
  This study aimed to establish the reference value range of healthy teeth mobility in Chinese youth.
  
  
  METHODS
  200 right side teeth of Han nationality of Chinese youths were measured so as to get the range of the parameters.
  
  
  RESULTS
  All parameters of 14 teeth were achieved. The parameter of TM in mandibular incisor was the highest and in mandibular first molar lowest.
  
  
  CONCLUSIONS
  It is very significant to get and quantify the healthy teeth's parameter range. Because they can be served as the healthy contrast when dentists diagnose the mobility. It also reflects the fact that lower the TM parameter is, firmer the tooth will be.
