Identification of human remains through comparing antemortem and postmortem dental records is a well-documented, accepted, and widely used procedure. Less well-known is the fact that the outline of the frontal sinuses seen in dental X-rays can be used to identify individuals even if they are edentulous. A series of cases is presented in which the identification of human remains was accomplished by comparing frontal sinus outlines found in dental or skull X-rays. The authors emphasize that antemortem radiographs of the head are an important and often overlooked source of antemortem records which can frequently provide objective data useful for comparison. 8 references and 6 figures (Author abstract modified)
