N2 - The analysis of panoramic radiographs of the jaws for forensic purposes is well established. The dental findings on the radiographs give valuable information concerning the identity and possible age. Panoramic radiographs also depict the zygomatic arches. Pneumatized spaces of the temporal bone's zygomatic arch process are asymptomatic variations, entitled "zygomatic air cell defect" (ZACD). Data on ZACD prevalence might support the current forensic-odontologic practice in the fields of identification and age assessment. The authors analyzed 6 studies subjected to evaluate ZACD on panoramic radiographs. The out-patients were subjected to systematic radiography prior to treatment planning in specialized dental or maxillofacial surgery clinics. The age of the 7870 patients varied between 6 and 97 years. ZACD was found in 169 patients (prevalence: 2.32%; female: 56.12%, male: 43.9%). Most ZACD were unilateral (70%). In these studies no ZACD occurred in children younger than 7 years of age. There was no statistically significant difference concerning ZACD prevalence in the sub-groups of children aged 9 to 13 vs. 14 to 17 years. This review demonstrates the prevalence of ZACD on orthopantomograms. The prevalence of this finding in the investigated children does not differ from the prevalences reported for adults, and is low in general. The presence of ZACD in persons might be valuable for the identification of humans or human remains and for age estimation in addition to other physical and dental findings.
