The Relationship Between Knowledge of Dental Caries and Dental Caries Experience Among Children Aged 10–12 Years

Abstract

Dental caries remains one of the most prevalent oral health problems among school-age children, particularly in the 10–14-year age group. Knowledge of dental caries is a key predisposing factor that can influence oral health behaviors, such as toothbrushing practices and dietary habits, which in turn affect caries experience. This study aimed to analyze the relationship between knowledge of dental caries and caries experience among children aged 10–12 years at SDN 12 Payakumbuh City. This analytical study employed a cross-sectional design involving 40 students selected through total sampling. Data were collected using a structured questionnaire to assess knowledge and clinical examination using the DMF-T index to measure caries experience. Data were analyzed using univariate and bivariate methods, with the chi-square test applied to determine the association between variables. The results showed that 37.5% of respondents had good knowledge, 55% had moderate knowledge, and 7.5% had poor knowledge. Regarding caries experience, 67.5% of respondents were categorized as having poor caries status (DMF-T > 1), while 32.5% were categorized as good (DMF-T ? 1). Statistical analysis revealed a significant relationship between knowledge and caries experience (p < 0.05). Children with better knowledge tended to demonstrate lower caries experience, likely through more favorable oral health behaviors. In conclusion, knowledge of dental caries is significantly associated with children’s caries experience, mediated by oral health behaviors. Strengthening oral health education programs is essential to promote preventive behaviors and reduce the burden of dental caries among school-age children. Early treatment, such as restorative care, is also recommended to prevent further complications.
