| Research Abstract |
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.
