Health Scientific study on food and dental diseases in Kenya

为了阐明牙科疾病和饮食方式之间的因果关系，该项目在肯尼亚共和国、英国和匈牙利进行。第一年，我们访问了8个地区办事处，准备进行以下调查。第二年，从1994年1月1日至2月22日，在洛德瓦尔、凯里乔和内罗毕对1,278名志愿人员进行了调查。由于肯尼亚方面的延期许可，我们不得不限制调查的地点和时间。然而，最初的计划，以及进行访谈，牙弓的印象，物理测量，肌电图，照片。第三年，进行了环境调查。伦敦的N.H.M.in、剑桥大学和布达佩斯的H.N.H.M研究了最近发现的肯尼亚骨骼遗骸（117具）。结果如下：1.膳食结构存在地区和代际差异。2. Lodwar的身体形态是高体重和低体重。3. Lodwar的错牙合和牙齿与义齿基托的差异百分比低于其他地区。4. Lodwar的咬肌活动略弱。与克里乔和内罗毕相比，洛德瓦居民患龋齿、牙龈炎等口腔疾病的比例较低。内罗毕的颞下颌关节功能障碍综合征发生率最高。6.现代和现代肯尼亚的下牙弓均观察到恒牙的放射性消融。

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.
