项目摘要

To confirm the effects of rapid transition of eating behavior on the jaw growth and the dental diseases in modern people, the adults (around 50) and the adolescents (high-teens) of both Australian white and aborigine who live in Perth, Western Australia were investigated. Numbers of subjects were 175.1. Dental diseasesThe average numbers of present teeth were 22 to 23 in the white adults, while they were 12 to 16 in the aboriginal adults. However, the average numbers of intact teeth were almost the same in both races. In the adolescents, the average numbers of present teeth were larger than those in the adults and there were no differences among both races. The periodontal indices were lower in the adolescents. But the aboriginal groups showed the higher indices in both generations.2. OcclusionIn the white adults, the normal occlusion were only at 35 to 40%, and the rest were the malocclusion such as the upper protrusion, the anterior cross bite and the crowding. In the aboriginal adul … More ts, the normal occlusion were at 73 to 75%. In the white adolescents, the normal occlusion were at 41 to 57%, including the orthodontically treated normal occlusion. In the aboriginal adolescents, the normal occlusion were only at 38 to 50%, and the rest were the upper protrusion, the anterior cross bite, the crowding and the open bite.As the pathogenic factors of malocclusion, the incidences of the discrepancy and the functional factors were less in the aboriginal adults. In the younger generation, however, those incidences were higher in both races. The degree of tooth attrition were grater in the aboriginal adults, and less in the younger generation.3. DietsAboriginal diets were generally higher in saturated fat and cholesterol than caucasian diets. Percentage of energy intake derived from carbohydrates, both simple sugars and starches, was similar for both races. However, caucasian males had a higher total intake of all forms of carbohydrate. The distribution of energy between macronutrients in aboriginal diets was similar to that in the national dietary surveys conducted 5 to 10 years ago. Less
为了证实饮食行为的快速转变对现代人颌骨发育和牙病的影响,对居住在西澳大利亚州珀斯的澳大利亚白人和土著成年人(50岁左右)和青少年(青少年)进行了调查。受试者人数为175.1人。牙病白人成人平均现齿数为22~23颗,原住民成人为12~16颗。然而,在两个种族中,完好牙齿的平均数量几乎相同。青少年的平均现牙数高于成人,且不存在种族差异。青少年的牙周指数较低。但原住民群体在两代人中都表现出较高的指数。结论在白人成人中,正常牙合仅占35%~40%,其余为错牙合,如上颌前突、前反牙合、拥挤等。在土著的adul…咬合正常率为73%~75%。在白人青少年中,正常牙合的比例为41%至57%,包括正畸治疗的正常牙合。在原住民青少年中,正常牙合仅为38%~50%,其余为上前突、前反牙合、拥挤和张开咬合,作为错牙合的致病因素,原住民成年人的错合和功能因素的发生率较低。然而,在年轻一代中,这两个种族的发病率都更高。原住民成年人牙齿磨耗程度较重,年轻一代牙齿磨耗程度较小。饮食土著饮食的饱和脂肪和胆固醇含量普遍高于高加索饮食。来自碳水化合物的能量摄入量百分比,包括单糖和淀粉,在两个种族中是相似的。然而,高加索男性对各种形式碳水化合物的总摄入量更高。原住民饮食中大量营养素之间的能量分配与5至10年前进行的全国膳食调查中的情况相似。较少
