RESUMO
A cross-sectional study was performed to evaluate whether dietary intake and nutrition contribute to the aetiology of common dental diseases in rural Bangladesh. Study subjects were selected following multi-staged stratified random sampling procedure. A total of 300 people of both sexes were included in the study with age ranging from 12-40 years. Data were collected for demographic and socio-economic condition, oral hygiene and related knowledge, dietary consumption, history and clinical findings. The study subjects were categorized as adequate nutrient and undernutrient by dichotomy based on their needed intake and the quality of diet consumed. The results showed that only 19% of the subjects had fulfilled their required intake and the rest were undernutrient. The results also showed that about 93% of the subjects were disease positive. The results between dietary intake and prevalence of diseases were statistically significant (p<0.05). From the findings of the study, it was concluded that low income, poor dietary intake, poor oral and general health may be jointly associated with higher prevalence of dental diseases in the rural community.
