The aim of this study was to compare the oral health status of migrants to Japan with that of Japanese using the questionnaire and the Oral Health Status Index (OHSI).
The questionnaire for collecting demographic and behavioral variables and the OHSI were applied in a mixed migrant/Japanese sample of patients from a dental clinic in Yokohama. A sample of 224 subjects, 52% of whom were migrants, was selected from new patients.
The mean OHSI scores were 78.56 for migrants and 83.16 for Japanese (p<0.01). Multiple regression analysis of OHSI showed that the statistically significant contributors were: age, status (migrants / Japanese), reason for initial visit, perceived oral health, and flossing behavior.
The oral health status of migrants was worse than that of Japanese even though they were younger than Japanese. The present public support system for foreign patients and their self-care behavior were considered to be the factors for the inequity in oral health status.
本研究旨在通过问卷调查和口腔健康状况指数（OHSI）比较移民到日本的人群与日本人的口腔健康状况。
在横滨一家牙科诊所的移民与日本患者混合样本中，应用了收集人口统计学和行为变量的问卷以及OHSI。从新患者中选取了224名受试者作为样本，其中52%为移民。
移民的OHSI平均得分为78.56，日本人的为83.16（p<0.01）。OHSI的多元回归分析表明，具有统计学意义的影响因素有：年龄、身份（移民/日本人）、初诊原因、自我感知的口腔健康状况以及使用牙线的行为。
尽管移民比日本人年轻，但其口腔健康状况仍比日本人差。目前针对外国患者的公共支持系统及其自我护理行为被认为是导致口腔健康状况不平等的因素。
