title: Applicability of  Demirjian's method of age assessment in a North Indian female population.
abstract: OBJECTIVE
  This study was conducted to determine whether the standards of dental maturation given by Demirjian et al.  are applicable to North Indian children and to assess the relationship between dental age and chronological age.
  
  
  METHODS
  In this study OPGs of 100 females of 8-14 years were taken, and dental age was calculated according to the  Demirjian method. Chronological age was recorded and compared to dental age.
  
  
  METHODS
  Collected data was  statistically analysed. Pearson's correlation coefficient was used to correlate the dental and chronological age of the 100  girls. The statistical analysis was done by using SPSS version 10.0 software (SPSS Inc., Chicago IL). For all tests the p-value  of <0.05 was considered for statistical significance.
  
  
  RESULTS
  A strong correlation was found between chronological and  dental ages.
  
  
  CONCLUSIONS
  In the present pilot work it was concluded that the Demirjian method of dental age assessment  showed high accuracy when applied to North Indian paediatric population.
