Association between the presence of an elongated styloid process, vascular calcification (atheroma) and the potential risk factor for osteoporosis was studied. Presence of an elongated styloid process was found to be correlated with systemic osteoporosis and also between elongated styloid process and atheroma.
The association between the presences of an elongated styloid process and vascular calcification (atheroma) with the potential risk factor assessment for osteoporosis was studied.
Bone mineral density obtained by dual energy X-ray absorptiometry diagnosed osteopenia/osteoporosis on at least two of three sites (column, hips, and forearm) of 50 female patients. Panoramic maxillomandibular radiographs were taken and analyzed. Elongation of the styloid processes was measured and the presence of atheromas in the carotid was investigated.
Eighty percent of the patients presented at least one side with elongated styloid process and the highest prevalence (87.5%) occurred in individuals between 60 and 69 years. Atheroma was found in four patients, three of which presented elongated styloid on at least one side and had diagnosed osteoporosis on at least two of the evaluated sites.
Correlation was found between the elongation of the styloid process and systemic osteoporosis, and between elongated styloid process and atheroma. The method in this study might be used as part of a method for osteopenia/osteoporosis and atheroma risk assessment.
研究存在细长型茎突、血管钙化（动脉粥样硬化）与骨质疏松潜在危险因素之间的关系。
50 例女性患者中，至少有两个部位（脊柱、髋关节和前臂）的双能 X 射线吸收仪检查诊断为骨量减少/骨质疏松症，获得骨密度。拍摄全景颌骨 X 光片并进行分析。测量茎突的长度，并检查颈动脉粥样硬化的存在情况。
80%的患者至少一侧存在细长型茎突，60 至 69 岁的人群中发病率最高（87.5%）。4 例患者发现有动脉粥样硬化，其中 3 例至少一侧茎突细长，并在至少两个评估部位诊断为骨质疏松症。
茎突的伸长与系统性骨质疏松症之间存在相关性，与动脉粥样硬化也存在相关性。本研究中的方法可用于评估骨质疏松症/骨量减少和动脉粥样硬化的风险。
