Morphometric bone assessment of men and women in different age range by cone beam computerized tomography

Osteoporosis corresponds to a decrease in bone mass and micro-architectural deterioration of bone tissue, causing bone fragility and risk of fractures. Although osteoporosis is four times more common in women than in men, they tend to have more complications with a higher risk of mortality after hip fracture. The silent nature of osteoporosis causes delays in early diagnosis, compromising adequate treatment. The objective was to evaluate bone morphometry and correlate morphometric indices between men and women, and between women of different age groups. The sample was divided into: men aged 65 to 75 years (A); women from 45 to 55 years (B1); women from 56 to 65 years (B2) and women from 66 to 75 years (B3). The morphometric indices Computed Tomography Cortical Index (CTCI), the Computerized Tomography Mental Index (MI), the Upper Mandibular Computerized Tomography Index (MCTI-U) and the Lower Mandibular Computed Tomography Index (MCTI-L) were analyzed by through the OnDemand3D software. There were significant differences between the different groups in MI, MCTI-L and MCTI-U and a high correlation between the indices. There was no difference in CTCI when used alone. There are differences in the bone structure of men and women, and between women of different age groups, and the quantitative and qualitative indices can be a useful tool in detecting patients with low bone density when used together for subsequent referral for bone densitometry and specialized medical treatment.
