title: No correlation between mandibular and non-mandibular measurements in osteoporotic men.
abstract: BACKGROUND
  Screening for low bone mineral density (BMD) using dual-energy X-ray absorptiometry (DXA) has been the traditional method for determining osteoporosis. Panoramic radiography is widely used in dentistry.
  
  
  OBJECTIVE
  To determine the relationships between the values of dental panoramic indices (the mental index (MI), antegonial index (AI), panoramic mandibular index (PMI)) and the values of skeletal BMD (femoral BMD (f-BMD), and vertebral BMD (v-BMD)) in 25 osteoporotic men.
  
  
  METHODS
  In the panoramic radiographs obtained from a total of 25 male individuals with osteoporosis, the means were calculated for MI, AI, and PMI values measured in the right and left mandible. DXA measurements of the femur and lumbar vertebrae BMD were also calculated. The correlation between these variables was assessed.
  
  
  RESULTS
  No correlation was found between the BMD values of the femur and lumbar vertebrae and values of MI, AI, and PMI.
  
  
  CONCLUSIONS
  No significant correlation was found between the mandibular and non-mandibular measurements in men with osteoporosis. MI, AI, and PMI indices should not be used in the evaluation of the skeletal status, because they are not reliable tools in screening for osteoporosis.
