ABSTRACT

The estimation of chronological age in the study of human remains is an essential task in order to reach objective conclusions regarding the person under study. The precision of this estimate is an important component of the study of anthropological and forensic contexts. An alternative approach is based on the measurement of the transparency of radicular dentine of permanent teeth. The present study tests this estimation technique on teeth from a skeletal collection of known age. Study design: the teeth under study are single rooted, structurally complete of secondary dentition. They derive from skeletal remains unearthed in a modern cemetery in the community of Caltimacán, State of Hidalgo. The teeth were prepared so as to favor the passage of the incandescent light beam through the root. transparency measurement was conducted with a digital calibrator that has a precision of hundredths of millimeters. Results: The correlation coefficient between the known and estimated ages based on the prediction table by Bang and Ramm (1970) is high, showing an index of 0.75. With regard to the age difference in the estimate, which represents an important parameter for establishing the technique’s efficiency, it was −3.06 in this study, thus indicating that the predictions underestimate the real age. Conclusions: The use of radicular transparency for the estimate shows a good fit and uncomplicated observation, even though it necessarily implies the availability of the teeth outside its alveolus.
