Abstract

The relationship between the height of the mandibular residual ridge and the severity of osteoporosis in elderly edentulous patients was investigated. The height of the mandibular residual ridge was measured by use of the mental foramen on panoramic radiographs. The severity of osteoporosis was determined by examining frontal and lateral radiographs of the vertebrae. All of the patients received a blood analysis. The correlation coefficient between age and the height of residual ridge was -0.38, which was statistically significant (p < 0.01). The residual ridge in women was lower than that of men, showing a statistical significance (p < 0.01). The correlation coefficient was -0.42 between degree of severity of osteoporosis and the height of the residual ridge, which was significant (p < 0.01). The parathyroid hormone level was high in the patients with a low residual ridge, and the calcitonin (CT) level was low. This study indicates that osteoporosis strongly affects reduction of the residual ridge in edentulous patients.

摘要

研究了老年无牙患者下颌剩余牙槽嵴高度与骨质疏松严重程度之间的关系。通过全景X线片上的颏孔来测量下颌剩余牙槽嵴的高度。通过检查脊椎的正位和侧位X线片来确定骨质疏松的严重程度。所有患者均接受了血液分析。年龄与剩余牙槽嵴高度之间的相关系数为-0.38，具有统计学意义（p < 0.01）。女性的剩余牙槽嵴低于男性，具有统计学意义（p < 0.01）。骨质疏松严重程度与剩余牙槽嵴高度之间的相关系数为-0.42，具有显著性（p < 0.01）。剩余牙槽嵴低的患者甲状旁腺激素水平高，而降钙素（CT）水平低。本研究表明，骨质疏松强烈影响无牙患者剩余牙槽嵴的吸收。
