Health Scientific study on food and dental diseases in Kenya

为了弄清牙科疾病与饮食方式之间的因果关系，这项计划在肯尼亚共和国、英国和湖南进行。第一年，我们走访了8个地区办事处，准备进行以下调查。第二年，即1994年1月1日至2月22日，对洛德瓦尔、克里科和内罗毕的1278名志愿人员进行了调查。由于肯尼亚的许可延迟，我们不得不限制调查的地点和期限。然而，最初的计划以及访谈、牙弓印象、体格测量、肌电图、照片都是执行的。第三年，开展了环境调查。最近的肯尼亚骨骼遗骸(117具)在伦敦的国立卫生研究院、剑桥大学和布达佩斯的国立卫生研究院进行了检查。研究结果如下：1.饮食风格存在地区差异和代际差异。在洛德瓦尔，人们的食物消耗量比克里科或奈罗比少。2.洛德瓦尔人的身体形态是高而低的。3.错牙合和牙齿与义齿基托的比例洛德瓦尔低于其他地区。4.洛德瓦尔的咬肌活动略弱，其温和的饮食模式与其他地区相比。5.洛德瓦尔的人比克里科和内罗毕的人更少的牙病，如龋齿或牙周炎。与其他地区的居民相比，内罗毕的颞下颌关节紊乱综合征发生率最高。6.在现代和最近的肯尼亚下牙弓中都观察到了恒牙的局部消融。在Lodward的儿童中检查乳牙的摘除。7.根据X线片头影测量，肯尼亚近期颅骨的牙面形态主要表现为上颌前突。

For the purpose of clarifying the causal-effect relationship between dental diseases and the dietary style, this project was carried out in the Republic of Kenya, in Great Britain U.K,and in Hungry.The first year we visited 8 district offices for the preparation of the following surveys. The second year, from January 1 to February 22,1994, a survey was conducted for 1,278 volunteers at Lodwar, Kericho and Nairobi. We had to limit both the place and the period of survey due to the delay for permission from the Kenya. However, the initial plans were performed as well as interviews, impression of dental arch, physical measurements, electromyography, photographs. The third year, investigation of the environment were carried out. Recent Kenyan skeletal remains (117) were examined at the N.H.M.in London, Cambridge University, and the H.N.H.M in Budapest. Results are as follows ;1.Regional and generational differences of dietary style were observed. In Lodwar, people had less food consumption than in Kericho or Nairobi.2.Physical morphologies in Lodwar were high and low weight.3.Both the malocclusion and the tooth-to denture-base discrepancy were shown to be lower in percentage in Lodwar than in the other districts.4.Activity of the Masseter muscle in Lodwar was slightly weak, and the gentle eating pattern was compared with the other districts.5.People in Lodwar had less dental diseases, such as carious teeth or gingivitis, than those in the Kericho and Nairobi. The syndrome of temporo-mandibular joint dysfunction in Nairobi was highest compared to inhabitants in other districs.6.Ritual ablation of the permanent teeth was observed both in the modern and recent Kenyan lower dental arch. The enucleation of the deciduous teeth was examined in the children in Lodwar.7.Dentofacial morphology of recent Kenyan skulls mainly showed the maxillary protrusion according to roentgenographic cephalometry.
