title: [Validity and reliability of the Demirjian distinguish software on estimating dental age].
abstract: OBJECTIVE
  To study the validity and reliability of the Demirjian distinguish software on dental age estimation.
  
  
  METHODS
  The dental age of 60 children were estimated with both the software three times and manual measures.
  
  
  RESULTS
  The correlation coefficients of dental age estimated by the software and by manual measure was 0.974 (female) (P > 0.1) and 0.970 (male) (P > 0.05); the coefficients of interclass correlation of each dental age estimated by the software was 0.977 (female) (P > 0.1) and 0.977 (male) (P > 0.05).
  
  
  CONCLUSIONS
  Demirjian distinguish software has high validity and reliability in estimating dental age.
