The purpose of this study is to analyze the risk factors of dental caries in primary school children. The subjects of this study were 77 students of SD Sendangmulyo 1 Semarang. We used questionnaires, diagnoses, and interviews for data collection. For data analysis, we used descriptive analysis method.
