This paper aims to report on two cases from Scientific Expertise Center - Renato Chaves, Belém- PA, where two individuals after committing crime, were referred to under 18s without supporting documents. Through data collected in the archives of the Scientific Expertise Center, an analysis of the mineralization of the teeth were made, highlighting the third molars by panoramic radiography; as well as the study of bone development of the hands and wrists of individuals through radiographs. After, the analysis was compared to surveys conducted by Nicodemos, Moraes and Médici-Filho, befitting the chronology of mineralization of permanent teeth among Brazilian citizens together with the work of Greulich-Pyle, Radiographic correlation concerning the chronology of the development of the hand and wrist. As a result of the analysis, it was obtained, for case 01, an estimated age of 17; and for case 02 the estimated age was between 18-19 years.
