Dietary Habit and Oral Health Status in Secondary School Students Attending a Dental Camp in Bangladesh: A Cross Sectional Study

Abstract

Background: Dietary habits, particularly frequent intake of sugary snacks and beverages, play a significant role in the development of dental caries and other oral health problems among adolescents. School-based dental camps provide an opportunity to assess oral health status and related behavioral factors.

Objective: To assess dietary habits and oral health status among secondary school students attending a dental camp and to determine the association between sugar consumption and dental caries.

Methods: A descriptive cross-sectional study was conducted among 300 secondary school students (aged 12–16 years) attending a dental camp in two selected secondary schools in Bangladesh. Data were collected through a structured questionnaire covering socio-demographic characteristics, dietary habits, and oral hygiene practices. Clinical oral examinations were performed using mouth mirror and probe under natural light to assess DMFT index (Decayed, Missing, Filled Teeth). Data were analyzed using SPSS version 22. Chi-square test was applied to determine associations; p<0.05 was considered statistically significant.

Results: Among 300 students, 52% were female and 48% were male. Majority (82%) reported daily consumption of sugary snacks, and 68% consumed soft drinks at least three times per week. Dental caries prevalence was 72%. Mean DMFT score found 2.36 ± 1.42. Students consuming sugary snacks more than once daily had significantly higher caries prevalence (p=0.001); irregular tooth brushing was also significantly associated with higher DMFT scores. (p=0.02)

Conclusion: High frequency of sugary food intake was strongly associated with increased dental caries among secondary school students. Regular school-based dental camps, dietary counseling, and oral health education programs are essential to improve adolescent oral health in Bangladesh.
