title: A comparative analysis of root dentin transparency with known age.
abstract: OBJECTIVE
  To correlate dimensions of root transparency and age, and to assess whether transparency is reliable for age estimation of unknown.
  
  
  METHODS
  50 freshly extracted single rooted permanent teeth from 50 different individuals (27 males and 23 females) were collected and their ground sections of 400 μm were stained with 1% methylene blue. The area of the translucent zone was measured by superimposing a transparent graph paper on the ground section under stereomicroscope. The length of the translucency was measured by using digital vernier caliper.
  
  
  RESULTS
  A strong positive correlation between age and translucency of dentin was noted. The length rather than the area of the translucent zone correlated more with age.
  
  
  CONCLUSIONS
  Translucency of the root dentin increases with age and it can be used as a reliable parameter for the age estimation.
