[en] Skeletal fluorosis continues to be endemic in many parts of India. Osteosclerosis and interosseous membrane calcification have long been regarded as hallmarks of this disease. Our study showed in addition a wide variety of radiological patterns: Coarse trabecular pattern, axial osteosclerosis with distal osteopenia and diffuse osteopenia. Subjects with osteopenic changes had a significantly lower dietary intake of calcium than those groups having normal radiological findings, predominant osteosclerosis or coarse trabecular pattern (p<0.001, p<0.01, and p<0.01 respectively). This suggests the role of calcium intake in determining the skeletal changes in endemic fluorosis. (orig.)
