| Outline of Final Research Achievements |
Since 1990, socioeconomic environment has changed drastically in Mongolia, change in traditional life style, food component, living environment and health system transition raised health related issues. The purpose of this study was to reveal etiologic mechanism of malocclusion and influence of malocclusion on children’s health, by comparative study of the maxillofacial morphology of Japanese and Mongolian with the same race but different environmental/social factors.
Our overseas scientific investigation of maxillofacial morphology in a population-based sample of Mongolia revealed that socioeconomic factors in adolescent children influence prevalence of malocclusion and that specific types of malocclusion, increased overjet and deep bite, were associated with oral health-related quality of life.
