title: Age estimation using maxillary central incisors: A radiographic study.
abstract: BACKGROUND
  In the field of forensic dentistry, secondary changes in teeth with advancing age have been used as reliable predictors of age in various studies.
  
  
  OBJECTIVE
  The purpose of the present study was to present a method for assessing the chronological age based on the relationship between age and morphological parameters of maxillary central incisors.
  
  
  METHODS
  Fifty subjects between 20-70 years of age were included in the study. Intraoral periapical radiographs were taken in relation to maxillary central incisors using paralleling technique. The following measurements were recorded: lengths of tooth, pulp, root and width of root and pulp at three different points. Regression formulas were used to calculate the dental age.
  
  
  RESULTS
  The mean estimated age showed no statistically significant difference from the actual mean age (P > 0.05). Also, maximum difference was seen for root length variable (-1.035 ± 1.86 years).
