Gingival emergence data for permanent teeth, obtained from an earlier cross-sectional study of 1137 Punjabi schoolchildren aged 6-14 years in Chandigarh, India, have been used to calculate the median age and the 10th-90th percentile range of age, for a given number of teeth present. From about 5 years (when the first tooth, on average, emerges) up to the time of emergence of second molars (around 14 years), the total number of permanent teeth emerged can be used to estimate the age of a child, with an error of about 13-34% of the median age for males and about 11-35% for females.
