| Resumo: | One of the main causes of mortality and morbidity in individuals aged 60 years and over is
bone fracture as a consequence of osteoporosis. It is known that low bone mineral density
(BMD) is a risk factor for these fractures, with bone densitometry being the gold standard test
for the diagnosis of BMD. Since the exam is expensive and not accessible for most of the
Brazilian population, alternative methods such as radiomorphometric indices obtained by the
panoramic radiographs analysis have been used to aid in the early identification of the low
BMD, acting as a possible screening of patients with high risk of osteoporotic bone fracture.
In this perspective, this research aimed to evaluate bone FR in the elderly through the clinical
fracture tool FRAX (Fracture Risk Assessment Tool) and to investigate its association with
radiomorphometric indices, obtained from panoramic radiography, related to BMD. It was an
observational cross-sectional and association study, 70 elderly people of both sexes were
evaluated in which underwent panoramic radiograph at the Dental Imaging Service of the
Department of Dentistry of UFRN. The images were analyzed by a trained researcher with
experience in radiographic interpretation. The application of the FRAX tool, as well as
obtaining the anamnesis was performed at the same time. It was observed that the sample
consisted mainly of women, with a median age of 68.5 years. The risk of major osteoporotic
fracture (MOF) presented a median of 4.2%, and the risk of hip fracture (HF) 1.3%. In order
to verify the associations between fracture risk and the independent variables of the study, the
Pearson and Mann-Whitney correlation tests were used. There was a statistically significant
association (p <0.05) between fracture risk and mental index (MI), age of menopause and
time of menopause. It is concluded that mandibular cortices with thinner thicknesses
measured by MI may represent an increased risk of osteoporotic bone fracture. |
