Panoramic radiomorphometric indices of the mandible in an Iranian population

Objectives: radiomorphometric indices measured on simple radiographic images can be used for qualitative and quantitative assessment of bone. Panoramic radiographic imaging can therefore assist dentists in early detection of osteoporosis in patients. Considering the effect of ethnic and environmental factors on development of osteoporosis and absence of normal values of radiomorphometric indices for the Iranian population, which results in use of normal values of other ethnicities for determining the presence or absence of osteoporosis in patients, the present study was conducted to evaluate radiomorphometric indices in patients presenting to a private oral and maxillofacial radiology clinic in Rafsanjan, Iran

Methods: the present cross-sectional study examined 385 eligible patients who met the inclusion criteria. Their demographic characteristics including age, gender and level of education were recorded. Their panoramic radiographic data, including radiomorphometric indices such as mandibular cortical index [MCI], antegonial index [AI], and gonial index [GI], were evaluated on each image. Multiple logistic regression was used to evaluate the effect of variables on mandibular bone radiomorphometric indices. P-value less than 0.05 was considered statistically significant

Results: the mean AI and GI were 2.19+/-0.56 and 0.87+/-0.31mm, respectively. In assessment of MCI, since none of the patients fell under the C3 category, all patients were categorized as C1 or C2. Assessment of demographic variables and radiomorphometric indices showed that age had a significant relationship with MCI and AI while gender had a significant relationship with GI

Conclusion: radiomorphometric indices can be used to assess the risk of osteoporosis in patients

Florid cemento-osseous dysplasia: report of three symptomatic cases

Florid cemento-osseous dysplasia [FLCOD] is a fibroosseous lesion that affects the jaw of middle-aged women. This lesion occurs more frequently in Black and Asians. A familial trend has been reported for some cases. This lesion may be completely asymptomatic and in such cases the lesion is detected in the radiographs incidentally. Radiographic features include multiple radiopaque masses, usually located in three or four quadrants or can be extensive throughout one jaw. However, when they are present in only one jaw, the mandible is the more common location. In this paper we report three cases of FLCOD that had evidences of infection as the first presentation
