Abstract

Abstract Objectives This study aimed to investigate socioeconomic‐related inequality in dental care service utilization in the past 12 months among Chinese preschool children and to explore the contribution of various factors to this inequality. Method A total of 40 305 children aged 3‐5 years from 372 kindergartens who participated in the Fourth National Oral Health Survey in China were included in the final analysis. The method of data weighting in complex sampling was adopted to make the samples more representative. Erreygers‐corrected concentration index (EI) was used to measure socioeconomic‐related inequality in dental care service utilization. The horizontal inequality index (HI) was employed to analyse horizontal inequality. Decomposition analyses were conducted to explore the contributions of income level, need variables (dmft, caregiver‐evaluated oral health status and toothache experience) and nonneed variables (caregiver education level, residential location, age, and sex) to the inequality of health service utilization. Result The utilization of oral health services within the past 12 months among the high‐, middle‐ and low‐income groups was 17.4% (95% CI: 15.6‐19.3), 13.6% (95% CI: 12.2‐15.1) and 9.4% (95% CI: 8.1‐11.0) respectively. The concentration curve was below the line of equality, and the EI and HI were 0.072 and 0.078, respectively, indicating that dental care utilization in children aged 3‐5 years was concentrated in those who were better off. The contribution of the need variables to socioeconomic‐related inequality in dental services was minimal, and most dental care utilization inequality could be explained by household income, caregiver education attainment and urban‐rural disparities, accounting for 32.0%, 49.4% and 20.4% respectively. Conclusion This study reveals the existence of pro‐rich inequality in dental care utilization among preschool children in China. The decomposition analysis suggests that income, caregiver education background and urban‐rural disparities are the main factors contributing to this outcome. Equity‐oriented policies and programmes are needed to achieve equitable dental care utilization.
