Abstract

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.

목적: 상, 하악골 혹은 치조골의 골밀도에 대한 지표를 나타낼 수 있는 방법의 개발은 치주질환의 관리, 치과 임플란트 치료 및 전신 골다공증의 진단 등에 유용하게 사용될 수 있다. 대상 및 방법: 팬텀을 포함하는 평행법 촬영기구(XCP)를 이용해 골밀도를 측정하고 이를 정량적 전산화 단층촬영 영상의 값과 비교하여 구강 내 치근단 방사선 영상을 이용한 골밀도 측정의 유용성을 평가하였다. 결과: 실험 결과 치조골의 골밀도에서 두 방법은 0.92 (P<.001)로 높은 상관관계를 보였고, 해면골에 국한된 골밀도는 0.73 (P<.001)으로 비교적 높은 유의한 상관관계를 보였다. 결론: 구강 내 치근단 방사선 영상을 통한 치조골 골밀도 측정의 가능성을 제시하였다.
