The aim was to explore the relation between radiographic bone quality on panoramic radiographs and relative alveolar bone level. Digital panoramic radiographs of 94 female patients were analysed (mean age, 44.5; range, 35-74). Radiographic density of the alveolar bone in the premolar region was determined using Agfa Musica software. Alveolar bone level and bone quality index (BQI) were also assessed. Relationships between bone density and BQI on one hand and the relative loss of alveolar bone level on the other were assessed. Mandibular bone density and loss of alveolar bone level were weakly but significantly negatively correlated for the lower premolar area (r = -.27). The BQI did not show a statistically significant relation to alveolar bone level. Radiographic mandibular bone density on panoramic radiographs shows a weak but significant relation to alveolar bone level, with more periodontal breakdown for less dense alveolar bone.
目的是探讨全景X线片上的影像学骨质量与相对牙槽骨水平之间的关系。分析了94名女性患者的数字化全景X线片（平均年龄44.5岁；范围35 - 74岁）。使用爱克发Musica软件测定前磨牙区牙槽骨的影像学密度。还评估了牙槽骨水平和骨质量指数（BQI）。评估了一方面骨密度和BQI与另一方面牙槽骨水平相对丧失之间的关系。下颌骨密度与下前磨牙区牙槽骨水平丧失呈弱但显著的负相关（r = -0.27）。BQI与牙槽骨水平未显示出统计学上的显著关系。全景X线片上的下颌骨影像学密度与牙槽骨水平呈弱但显著的关系，牙槽骨密度越低，牙周破坏越严重。
