Purpose: This study was initiated to assess the oral health status and identify factors associated with dental caries in children from Zhoushan.
Methods and Materials: A total of 125 children aged 5–12 years old were selected for oral examinations at the paediatric dentistry department of our hospital. The dental caries status of the children was examined and recorded, and a questionnaire was administered to their caregivers. The questionnaire collected data on patients’ awareness of oral health, supervision of children’s toothbrushing, assessment of brushing effectiveness, as well as dietary habits, oral behaviours, and oral healthcare practices. Univariate and multivariate logistic regression analyses were employed to analyse the relationships between the prevalence of dental caries and the selected variables.
Results: The caries rate among the 125 children was 62.40%. Logistic regression analysis showed that the use of fluoride toothpaste, brushing ≥ 2 times per day, and brushing after eating were protective factors against dental caries in children (OR < 1, P < 0.05). In contrast, age at initiation of brushing > 3 years, consumption of sweets and beverages ≥ 2 times per week, and frequent bedtime eating were likely to increase dental caries risk in children (OR > 1, P < 0.05).
Conclusion: In view of the identified factors contributing to dental caries in children, it is important to strengthen oral hygiene education for both parents and children. Promoting standardised dental caries prevention and treatment practices and cultivating good oral hygiene habits among children are essential for improving their oral health.
