Abstract
This study describes the gingivitis status and examines associated factors among Mong ethnic primary schoolchildren at San Sa Ho Primary School, Sa Pa town, Lao Cai province, in 2025. A cross-sectional design was applied to 251 children aged 7 - 11 years. Gingivitis was assessed using the Gingival Index (GI) of Löe and Silness, combined with interviews on oral health behaviors. The prevalence of gingivitis was 72.9%, predominantly mild and moderate. No significant difference was observed by sex, while the prevalence tended to increase with age. Not brushing teeth daily, lack of regular dental check-ups, and maternal education below lower secondary level were significantly associated with gingivitis (p<0.05). These findings indicate that gingivitis remains a common oral health problem among Mong ethnic primary schoolchildren in a mountainous school setting and highlight the need for school-based preventive oral health interventions tailored to local conditions.
