Evaluation of alveolar bone density by intraoral periapical radiography / 대한치과보철학회지

PURPOSE: A method detecting change of jaw or alveolar bone density may be helpful in periodontal care, implant dentistry and evaluation of bone density of whole body. MATERIALS AND METHODS: In this study, bone density of intraoral periapical radiography using phantom-integrated XCP is compared with that of quantitative computed tomography (QCT). RESULTS: Bone density of intraoral periapical radiography and the one measured by QCT showed high correlation (correlation coefficient = 0.92, P<.001) in alveolar bone, and relatively high correlation (0.73, P<.001) in cancellous bone. CONCLUSION: This study revealed possibility of scoring of bone density by intraoral periapical radiography.
