The risk assessment index for tooth mobility through bone density analysis in the pre-elderly and elderly

Bone mineral density is the amount of bone mineral content in cm2, and it can be classified as normal, osteopenia, and osteoporosis. This study conducted a risk assessment of tooth mobility using bone density analysis. Low bone density, which is associated with osteopenia/osteoporosis, can directly affect the alveolar bone's micro architecture and cause tooth mobility. This study consisted of 22 men and 56 women participants aged = 50 years. Mandibular bone density measurements were performed using panoramic radiographs and periapical Direct Digital Intraoral Radiograph (DDIR) analysis. Bone mineral density measurements were performed using a Quantitative Ultrasound (QUS). The results showed a relationship between tooth mobility and both oral hygiene and bone mineral density (P=.000, P=.035, respectively).An index was created to estimate mobility greater than or equal to 50% of mandibular teeth.
