【摘要】 目的探讨维吾尔族牙周炎患者的下颌骨骨密度。方法选择中度慢性牙周炎的维吾尔族成人患者20例(男性9例,女性11例,平均年龄25.6岁),另选择无牙周炎的维吾尔族成人患者20例(男性12例,女性8例,平均年龄23.5岁)作为正常对照,40例患者均拍摄数字化全颌曲面断层片,采用曲面体层下颌指数(PMI)为测量指标分析样本的下颌骨骨密度。结果正常对照组sPMI值为0.301±0.126,iPMI值为0.364±0.091;牙周炎患者sPMI值为0.246±0.046,iPMI值为0.318±0.075。两组的PMI指数差异有显著性(P<0.05)。结论维吾尔族牙周炎患者下颌骨骨密度值较正常组低。PMI指数反映了下颌骨皮质骨量的变化,间接反映了下颌骨的骨密度,为检测下颌骨骨密度提供了简便、直观的方法。同时,下颌骨骨密度的测定结果可能提示全身骨密度情况,但仍需后期结合腰椎、前臂远端1/3的骨密度测定等骨质疏松诊断方法,使其得到早期防治。更多还原

【Abstract】 Objective To investigate the bone mineral density on mandible in Uygur patients with periodontitis.Methods 20 Uygur adult patients with chronic periodontitis had been selected(9 males,11 females,the average age was 25.6 years old).20 Uygur adult patients without periodontitis had been selected(12 males,8 females,the average age was 23.5 years old) as control group.All the 40 patients took the digital panoramic radiography photos.Measuring and analysis bone mineral density on mandible by using panoramic mandible index(PMI).Results In control group,sPMI was 0.301±0.126,and iPMI was 0.364±0.091;In the group with periodontitis,sPMI was 0.246±0.046,and iPMI was 0.318±0.075.there were statistically significant differences between the two groups’ panoramic mandible index(P<0.05).Conclusions The bone mineral density of mandible in Uygur patients with periodontitis was lower than the Uygur patients without periodontitis.Panoramic mandible index reflect the capacity of substantia compacta in mandible directly.And it reflects bone mineral density of mandible indirectly.Panoramic mandible index provided a convenient and intuitional method to measure bone density of mandible.Meanwhile,the result of bone density in mandible can indicate bone density of the whole body,we should also diagnose osteoporosis with the bone density in lumbar vertebral and in 1/3 of prior arm,in order to prevent osteoporosis earlier.更多还原
