Age Estimation from Teeth with Critical Analysis of Gustafson's Method

In this era of evidence based medicine much of expertise in field of Forensic Odontology is drawn from basic research and experience. Teeth are better preserved than other material, so their use for identification of an individual's age at death is very important. Ever since its inception Gustafson's method for determination of age from permanent teeth is considered gold standard even though many workers have dealt with the topic extensively, and critically determined the error factors involved. The present study reveals that the central incisor is the best age indicator with a standard error of ±6.35 years, and in combination of canine and first molar gives age estimation within an error of ±5.35 years. The first molar alone being the first to erupt in permanent series is found less useful age indicator (error±8.15 years). In contradiction to many researchers and Gustafson himself, this study points that attrition constitutes the most reliable parameter.
