Background: Osteoporosis is related to the decrease of bone density, osteoporosis requires attention from dentists because it can also occurs in the jaw bone. Osteoporosis is calculated with a quantitative assessment of bone density, which is called Bone Mineral Density (BMD). The best imaging modalities to assess bone density are the Dual Energy examination methods X-ray Absorptiometry (DEXA). In addition to DEXA, osteoporosis examination can be performed with measurement of Body Mass Index (BMI), which is a ratio of weight and height. Process of bone formation by osteoblasts can be examined by bone marker such as Osteocalcin, as a parameter (alone or in combination with BMD) to determine metabolic bone disorders during bone formation and bone remodeling (bone turnover).
