Common questions
Why use a population-specific standard instead of an international dental atlas?+
Tooth eruption timing varies with genetics, nutrition, and environment across populations, so applying a Western reference atlas to an Indian child can systematically bias an age estimate; ICMR data corrects for this by using local samples.
Does using ICMR standards remove all uncertainty from a dental age estimate?+
No. Dental development still varies between individuals of the same population, so examiners report an age range with a stated confidence interval rather than a single exact age.
