Abstract
BackgroundThe interactions between torus and several factors such as age, gender, and dental status have not been studied comprehensively. The purpose of this study was to determine the effect of gender on the mandibular cortical index (MCI) and to investigate a possible association between torus mandibularis (TM) and MCI.MethodsThe study consisted of 189 consecutive patients referred to Department of Oral Diagnosis and Radiology of Hacettepe University within 30 workdays. Patients who did not have systemic disorders affecting bone density were included; and the age, gender, dental status and existing TM of the patients were recorded. Morphology of the mandibular inferior cortex was determined according to Klemitti's classification on panoramic radiographs.ResultsMCI was affected by age and gender (P < 0.05). No significant relationship was found between TM and MCI (P > 0.05).ConclusionIn the study population, MCI was affected by age and gender. As age increased, semilunar defects could be seen on the cortex of the mandible and MCI values increased. Women appeared to have higher MCI values than men.
Highlights
The interactions between torus and several factors such as age, gender, and dental status have not been studied comprehensively
bone mineral density (BMD) can be evaluated by techniques such as computed tomography [4] and dual energy x-ray absorbsiometry (DEXA)
Because the radiographic appearance of the jaws change in osteoporotic patients, the relationship between the mandibular morphology and the rate of osteoporosis can be quantified by the determination of the thickness and completeness of mandibular inferior cortex
Summary
The interactions between torus and several factors such as age, gender, and dental status have not been studied comprehensively. Good skeletal mineral status is related to physical and muscular activity [2], and bone mineral density (BMD) may be considered as an essential component of bone quality [3]. Because the radiographic appearance of the jaws change in osteoporotic patients, the relationship between the mandibular morphology and the rate of osteoporosis can be quantified by the determination of the thickness and completeness of mandibular inferior cortex. This may provide the opportunity of early identification of osteoporotic patients, who need treatment [5].
