ABSTRACT
Unaccompanied migrant minors are increasingly seeking asylum status in the United States (U.S.) where guidelines for age assessment call for the use of multiple forms of evidence. A commonly used approach in the U.S. is dental radiographs to assess the root development of third molars. Not only has research shown this methodology to be unreliable and imprecise, but the evidence has shown significant variability in dental development by chronologic age, race/ethnicity, sex, socioeconomic status, systemic disease, nutritional health, and other environmental factors. Misclassification of minors as adults based upon the imprecise tool of dental age assessment can have serious and harmful consequences. In the U.S., this misclassification has resulted in the housing of minors with adults in Immigrant and Custom Enforcement (ICE) operated jails. In addition, there are significant ethical concerns with regard to the use of radiographs for purposes that are neither diagnostic nor therapeutic and the lack of informed consent. In this commentary we review the (1) inadequacy of dental radiographs as a means of chronologic age assessment for minors, and (2) the ethical implications of implementing this flawed and inappropriate assessment on a highly vulnerable population.
