Osteoporosis is a common disease that makes the bones fragile and easy to break. Osteoporotic fractures are a serious health problem resulting in pain, reduced mobility, increasing degree of dependence and sometimes death.
Osteoporosis is currently diagnosed by measuring bone density at the hip/spine through an exam called DXA. Although all post-menopausal women are at higher risk, currently Italian national guidelines do not recommend population-screening programs. This leads to several cases not being identified before a fracture occurs.
Since dental panoramic radiographs (OPGs) are common procedures during dental check-ups or before dental treatments, it would be of great value if dentists could use them to identify people with unknown osteoporosis and early refer them to a specialist before they fracture.
This study aims to test if it is meaningful to use OPGs to screen for post-menopausal osteoporosis. In particular, it will inform on how many undiagnosed osteoporotic women attend a Dental Hospital, how willing they are to have a DXA scan after a dental appointment and how precise the OPGs are as screening tools.
124 post-menopausal women will be recruited, which will undergo an OPG and a DXA scan to check their bone density.

Diagnostic Test: Dental panoramic radiograph
If not performed within the previous 6 months at the Centre of Dentistry, an OPG will be performed during enrolment visit.
OPGs are routine low-dose x-rays that are often performed during dental check-ups, follow-ups or before dental treatments (e.g. extractions, implant placement, etc.), as they allow the evaluation of both bone and dental structures of both jaws, the sinus and temporo-mandibular joints.
Diagnostic Test: DXA
On Visit 2, a DXA scan of the hip and lumbar spine will be performed, with the Hologic QDR-4500 Acclaim densitometer owned by the University of Parma and located at the "Centro Osteoporosi e malattie metaboliche scheletriche", if not already available from the previous 6 months.
DXA is a low-dose exam that allows the measurement of bone mineral density in relation to a T- score, and is considered the gold-standard for the diagnosis of osteoporosis.
Patients will be classified into healthy (T score -1), osteopenic (T score between -1 and -2.5) and osteoporotic (T score-2.5).
- sensitivity and specificity of Klemetti Index [ Time Frame: At study completion (end of visit 2), so within 6 months from enrolment (visit 1) ]To assess the sensitivity and specificity of Klemetti Index (KI) to screen for osteoporosis in postmenopausal women attending the Centre of Dentistry at the University of Parma
- sensitivity and specificity of mandibular cortical width [ Time Frame: At study completion (end of visit 2), so within 6 months from enrolment (visit 1) ]To assess the sensitivity and specificity of mandibular cortical width (MCW) to screen for osteoporosis in postmenopausal women
- sensitivity and specificity of panoramic mandibular index [ Time Frame: At study completion (end of visit 2), so within 6 months from enrolment (visit 1) ]To assess the sensitivity and specificity of panoramic mandibular index (PMI) to screen for osteoporosis in postmenopausal women
- Precision and reproducibility of Klemetti index [ Time Frame: At study completion (end of visit 2), so within 6 months from enrolment (visit 1) ]Two blind examiners will calculate the index twice (within at least one week from the first evaluation) and intra and inter examiner reproducibility will be assessed through Kappa statistics
- Number of undiagnosed osteoporotic women [ Time Frame: during the 9 months of recruitment ]To record the number of undiagnosed post-menopausal osteoporotic women attending a University Dental Hospital (Centro Universitario di Odontoiatria)
- number of osteoporotic women requiring treatment [ Time Frame: during the 9 months of recruitment ]To record the number of osteoporotic women identified as osteoporotic as part of the study that would require pharmacological treatment (based on the Italian modified version of FRAX "DeFRA", and on the Consultant Rheumatologist's advice)
- % of post-menopausal women willing to be screened for osteoporosis after a dental appointment [ Time Frame: during the 9 months of recruitment ]This will be calculated as the percentage of post-menopausal women meeting the inclusion/exclusion criteria and willing to be screened for osteoporosis after a dental appointment (and therefore enrolled) out of all the patients approached.
