Abstract
OBJECTIVE: This investigation was performed to calculate radiomorphometric indices in panoramic radiographs and identify possible relationships between these indices and sex, age, and body mass index of patients in Saudi and non-Saudi populations. METHODS: In total, 955 panoramic radiographs were reconstructed from cone-beam computed tomography volumes of 133 male and 167 female patients (age range, 20–75 years; mean age ±standard deviation, 50.8 ± 8.9 years). Three panoramic indicators were calculated for Saudi and non-Saudi participants according to sex and age: the mental index (MI), panoramic mandibular index (PMI), and antegonial index (AGI). RESULTS: The MI and AGI were significantly different between the two sexes, and the MI was significantly different between the Saudi and non-Saudi participants. Patients aged 20 to 40 years showed a significantly larger MI, PMI, and AGI than patients aged 40 to 60 years and patients aged >60 years. CONCLUSION: The findings of the present study revealed that the MI, PMI, and AGI were significantly different between the two sexes, among various age groups, and between Saudi and non-Saudi participants.
