Age Estimation of Karachi Children by Erupted Permanent Teeth, Dieting Habits and Anthropometric Measurements.
Ann Jinnah Sindh Med Uni Jan ;1(2):12-4.

Objectives: To develop a suitable model to estimate the age of the Karachi children using total number of permanent teeth erupted, anthropometric measurements and milk intake. Methodology: Four thousand five hundred and eighty (4580) schoolchildren of just erupted teeth' of 102 private and public school of Karachi were included in this study. The children were examined under fluorescent light by the dentists and the height and weight were measured by the assistants. School record was used to collect the date of birth. Linear regression analysis was used to develop models with explanatory variables; number of teeth erupted, height, weight and milk intake. Explanatory variables: Model 1: number of teeth; Model 2: number of teeth, height and weight; Model 3: number of teeth, height, weight and milk intake. Results: The mean height and weight of the children were 129.09 ± 13.72 (R: 88-198) cm and 25.95 ±8.62 (R: 9-90) kg respectively. The average glass of milk consumed by the children per week was 7.02 ± 2.74 (R: 0-28). Results showed that percentage of difference of two ages (estimated and actual) fallen within ±0.5 years were 34.11, 35.93 and 36.71 for model 1, 2 and 3 respectively. Furthermore, these percentages within ±1.0 years were 60.61, 63.16 and 65.11, respectively. Conclusion: Study showed that by adding milk intake by the children in the regression equation improved the accuracy in age estimation.
