This study aimed to evaluate the validity of panoramic radiography as an auxiliary method for identifying mandibular bone features consistent with a diagnosis of osteopenia or osteoporosis. Ninety panoramic radiographs were analyzed to assess the quality of the mandibular cortical layer below the mental foramen on both sides of the mandible. Scores C1 (normal), C2 (osteopenia), and C3 (osteoporosis) were attributed according to the cortical morphology. The sample consisted of 78 (86%) women aged 45 years or older and 12 (14%) men older than 60 years old. In 39 (43%) cases, the C1 score was evidenced as the lower mandibular cortical layer was normal on the image. The C2 score was identified in 47 (52%) cases, in which the cortical layer showed semilunar defects. Four (5%) cases presented a C3 score, with the cortical layer showing a clearly porous, thinner bone cortex. The presence of risk behaviors (e.g., smoking and alcoholism) as well as some comorbidities (e.g., systemic arterial hypertension, diabetes mellitus and thyroid disorders) was also observed. Mandibular bone changes were observed in association with a set of risk factors using panoramic radiography.
本研究旨在评估全景X线摄影作为一种辅助方法，用于识别与骨质减少或骨质疏松诊断相符的下颌骨特征的有效性。分析了90张全景X线片，以评估下颌骨两侧颏孔下方下颌骨皮质层的质量。根据皮质形态给予C1（正常）、C2（骨质减少）和C3（骨质疏松）评分。样本包括78名（86%）45岁及以上的女性和12名（14%）60岁以上的男性。在39例（43%）病例中，图像显示下颌骨皮质层正常，证实为C1评分。47例（52%）病例为C2评分，其中皮质层显示半月形缺损。4例（5%）病例为C3评分，皮质层显示明显多孔、较薄的骨皮质。还观察到存在风险行为（如吸烟和酗酒）以及一些合并症（如系统性动脉高血压、糖尿病和甲状腺疾病）。使用全景X线摄影观察到下颌骨变化与一组风险因素有关。
