Application Of Tooth Coronal Index (TCI) Benindra Method In Estimating Biological Age at Sultan Agung Dental Hospital Semarang

Abstract

Background: Estimation of age through teeth is one way to identify living and dead individuals. Age estimates can clarify statements of death, legal and civil matters. One way to identify victims is using periapical radiographs. The use of periapical radiographs in age estimation requires certain method, one of which is the TCI (Tooth Coronal Index) Benindra method modified from Drusini's TCI method. Tooth age assessment using Benindra TCI method based on pulp chamber height measurements.Purpose: to clarify the application of TCI Benindra method in estimating biological age in Semarang population. Material and Method: This research was using total sampling method with a number of 23 periapical radiographs with 7 male and 16 female. The estimated age of the Benindra TCI method was done at the age of 9-21 years and using a mandibular premolar. Tooth age assessment was based on measurements of pulp chamber height using the TCI formula, the results of TCI measurements were entered into the prediction age formula to determine the biological age. Result: the average difference between biological age estimated used the Benindra method and chronological age reached 0,46 years in the 9-21 years age group. There were 7 data that underestimated, 6 data over estimation, and 10 data on estimation.Conclusion: The application of the Benindra TCI method shows good results in estimating the biological age of the Semarang population, because the difference between the estimated age and the chronological age produced by this method is quite small.
