Is the Burden of Dental Caries Higher in a Private Kindergarten Compared to the National Prevalence?

Abstract

Background:
Dental caries remain highly prevalent among Malaysian preschoolers. However, government-funded oral health programmes have mainly targeted public preschools, often overlooking children in private institutions.

Objective:
This study aimed to investigate the prevalence and experience of dental caries, plaque scores, and oral hygiene status among children attending a private kindergarten in Selangor, Malaysia. It also assessed their oral health knowledge, attitudes, and behaviours and compared the findings with national averages.

Methods:
A pilot study was conducted among 100 preschool children aged 4–6 years at a private kindergarten. Oral examinations assessed dental caries and plaque scores using standard indices. A validated questionnaire collected data on oral health knowledge, attitudes, practices, and dietary habits. Statistical analysis was performed using SPSS version 22.

Results:
Among 87 children who participated in the clinical exam, the dental caries prevalence was 56.3% with a mean dmft score of 2.43, both lower than national averages. The mean plaque scores were 20.5% overall and 16.5% for anterior teeth. Oral hygiene was rated excellent in 50.6% of children. From the questionnaire (n=40), most children had good oral health knowledge but lacked awareness about the effects of plaque and sugary drinks. Positive brushing habits were observed, though many failed to brush for the recommended duration. Dietary habits were also generally healthy, with low soft drink and sweet food consumption.

Conclusion:
The findings suggest a lower burden of dental caries and better oral hygiene status in this private preschool population compared to national data. Despite this, gaps in specific oral health knowledge and behaviours remain. Future oral health programmes should include private preschool settings to ensure broader preventive coverage.
