Resumo
Osteoporosis is a disease characterized by
bone mineral density reduction, weakening
the bone structure. Its diagnosis is
performed using ionizing radiation, increasing
health risk. Optical techniques are safer,
due to non-ionizing radiation use, but limited
to the analyses of bone tissue. This limitation
may be circumvented in the oral
cavity. In this work we explored the use of
laser speckle imaging (LSI) to differentiate
the sound and osteoporotic
maxilla andmandible bones in an in vitro model. Osteoporosis lesions were simulated
with acid attack. The samples were evaluated by optical profilometry and
LSI, using a custom software. Two image parameters were evaluated, speckle contrast
ration and patches ratio. With the speckle contrast ratio, it was possible to
differentiate sound from osteoporotic tissue. From speckle patches ratio it was
observed a negative correlation with the roughness parameter. LSI is a promissory
technique for assessment of osteoporosis lesions on alveolar bone.
