目的 本研究的目的是调查全民公共健康保险体系下的日本成年人的牙列状况是否存在教育梯度。方法 研究对象为截至2005年5月的1201名年龄在55-75岁的社区居民，他们填写了自填式问卷，并进行了标准的临床口腔检查。分析的重点是三个教育水平（初中、高中和任何大学或高等教育）与牙列状态的关联。结果 拥有 20 颗或更多牙齿的受试者比例 (P < 0.001)、存在的牙齿数量 (P = 0.037)、填充的牙齿数量 (P = 0.016) 以及两种类型的功能性牙齿单位 (FTU)：天然牙 FTU (n-FTU) (P < 0.001) 以及种植体支持和固定修复体上天然牙和人造牙的 FTU (nif-FTU) （P < 0.001）在调整混杂因素后与教育水平显着相关。这些牙齿指数值的显着趋势表明，受教育程度较低的人牙列状况较差。结论 结果表明，即使考虑到口腔健康相关因素，教育水平对一组日本成年人的牙列状态也有独立影响。因此，在义务学校教育计划中从小就提供适当的口腔健康信息似乎有必要提高健康素养并减少教育水平之间的牙齿健康不平等。
Objectives The aim of this study was to examine whether there is an educational gradient in dentition status among Japanese adults who are under the universal public health insurance system. Methods Subjects were 1201 community residents aged 55-75 years as of May 2005 who completed a self-administered questionnaire and had a standard clinical oral examination. Analysis focused on the association of three education levels (junior high school, senior high school, and any college or higher education) with dentition status. Results The proportion of subjects with 20 or more teeth (P < 0.001), number of teeth present (P = 0.037), number of filled teeth (P = 0.016), and two types of functional tooth units (FTUs): FTUs with natural teeth (n-FTUs) (P < 0.001) and FTUs with natural teeth and artificial teeth on implant-supported and fixed prostheses (nif-FTUs) (P < 0.001) were significantly associated with education level after adjusting for confounders. The significant trend of these values in dental indexes indicated a poorer dentition status with a lower education level. Conclusions The results suggest that the level of education has an independent impact on dentition status in a group of Japanese adults, even after taking into account oral health-related factors. Therefore, providing appropriate oral health information from an early age within a compulsory school education program appears necessary to enhance health literacy and lessen the inequalities in dental health by educational level.
