On a panoramic radiograph, when counting missing teeth in an adult, you note multiple missing teeth. This finding is MOST consistent with:

Dental terminology for missing teeth: Hypodontia = 1–5 missing teeth (excluding third molars). Oligodontia = 6 or more missing teeth. Anodontia = complete absence of all teeth. When a panoramic shows 'many' missing teeth, oligodontia is the appropriate term if 6+. Ectodermal dysplasia is the most common systemic association with oligodontia.
