1)对14,692名神户地震受灾成年人进行口腔健康检查。结果显示，在50岁以上年龄组中，CPI为0的受试者的牙槽骨密度(DMFT)显著低于CPI3和4的受试者，尤其是DT和MT(P&lt；0.01)。2)在50岁以上的桥位X线片检查对象中，将受试者分为4组：(1)无水平组、(2)少数组、(3)中度组、(4)重度组。在生活方式相关因素中，NO水平组有吸烟习惯(P&lt；0.05)、体重指数较低(P&lt；0.05)、有规律饮食习惯(P&lt；0.05)的比例较低。但每日刷牙次数和牙科诊所就诊次数无显着性差异。(3)无牙位组的牙冠数和牙位数较少(P&lt；0.01)。NO水平组与健康20‘S组比较，左、右同类型牙齿咬合力差异均小于健康20’S组(P&lt；0.01)。

1) 14,692 adults who suffered earthquake in Kobe were participated in oral health examination. The results showed that in over fifty aged subjects group, subjects with CPI 0 had fewer DMFT, especially DT and MT than subjects with 3 or 4 (P<0.01)2) Among over fifty aged examinee of ponorama X-ray examinatin, subjects were divided into four groups with focus on level of alveolar bone loss ((1)No level group, (2)A few group, (3)Moderate group, (4)Severe group).
