Objective:
To correlate dimensions of root transparency and age, and to assess whether transparency is reliable for age estimation of unknown.
Materials And 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.
Conclusion:
Translucency of the root dentin increases with age and it can be used as a reliable parameter for the age estimation.
