Abstract
OBJECTIVES: To evaluate the antegonial index (AI) and the mental index (MI) in edentulous and dentate patients, in different age groups and between genders. STUDY DESIGN: We evaluated 312 panoramic radiographs and grouped them into 4 10-year age groups. Gender, dentition status and age were recorded. The measurements were performed by 2 researchers independently. RESULTS: The AI and MI were significantly smaller in older females, whereas they were greater for older males (P < 0.01). Edentulous individuals had a lower AI than dentate and partially dentate individuals (P < 0.01). CONCLUSIONS: There is a continuous remodelling in the mandibular cortex with age and this is influenced by dental status and gender. The difficulty of measuring the AI in a reproducible manner, its interaction with dental status and low correlation with MI in younger patients should discourage its use in detecting patients at risk of osteoporosis.
