拥有不同口腔卫生保健系统的国家可能存在不同程度的口腔健康相关不平等。我们比较了日本和英国老年人口腔健康方面的社会经济不平等。我们使用了日本（N = 79,707）和英国（N = 5115）65岁或以上成年人的数据，并根据教育程度和收入估计了无牙颌（没有天然牙齿的情况）的绝对不平等（不平等斜率指数，SII）和相对不平等（不平等相对指数，RII）。所有分析均根据性别和年龄进行调整。总体而言，14% 的日本受试者和 21% 的英国受试者无牙颌。在日本和英国，较低的收入和教育程度与较高的无牙颌风险显着相关。日本和英国以教育为基础的 SII 分别为 9.9% 和 26.7%，RII 分别为 2.5 和 4.8。日本和英国基于收入的 SII 分别为 9.2% 和 14.4%，RII 分别为 2.1 和 1.9。这两个高收入国家都存在无牙颌个体的社会不平等现象，但日本的牙科保健覆盖范围较广，其不平等程度低于英国。
Countries with different oral health care systems may have different levels of oral health related inequalities. We compared the socioeconomic inequalities in oral health among older adults in Japan and England. We used the data for adults aged 65 years or over from Japan (N= 79,707) and England (N= 5115) and estimated absolute inequality (the Slope Index of Inequality, SII) and relative inequality (the Relative Index of Inequality, RII) for edentulism (the condition of having no natural teeth) by educational attainment and income. All analyses were adjusted for sex and age. Overall, 14% of the Japanese subjects and 21% of the English were edentulous. In both Japan and England, lower income and educational attainment were significantly associated with a higher risk of being edentulous. Education-based SII in Japan and England were 9.9% and 26.7%, respectively, and RII were 2.5 and 4.8, respectively. Income-based SII in Japan and England were 9.2% and 14.4%, respectively, and RII were 2.1 and 1.9, respectively. Social inequalities in edentulous individuals exist in both these high-income countries, but Japan, with wider coverage for dental care, had lower levels of inequality than England.
