Nutritional Status, Prevalence of Early Childhood Caries, and its Association among Preschool Children in Northeast India.

Background: Early childhood caries (ECC) is a common public health problem in developing countries. Children with severe decay can also have altered eating habits and preferences. Therefore, ECC can influence nutritional health.

Aim: The aim is to find the prevalence of ECC and nutritional status and to evaluate its association among preschool children in Northeast India.

Study design and data collection methods: This descriptive cross-sectional study was conducted among 384 preschool children aged 2-6 years. The sampling unit comprised the children attending the pediatric dentistry department of one dental college. Information regarding sociodemographic factors, child feeding habits, and child oral hygiene practices was obtained from the parents using a pretested questionnaire. Weight and height were evaluated to assess the nutritional status. The decay, missing, filled teeth index for primary teeth was used to determine the dental caries status.

Results: The mean value of carious teeth for 384 children aged 2-6 years was 5.6 ± 2.43. Most kids who had caries (74.7%) belonged to the moderate category (dmft >7), followed by the low sort, which was 16.7%, and then by those in the higher class (8.6%). The body mass index (BMI) for age revealed that 5.2% were overweight, 15.1% were thin, and 8.3% were obese. Most of those with high caries (i.e., dmft >7) were underweight or in the normal weight category. Pearson correlation showed no significant correlation between ECC with BMI-for-age (r = 0.04, P > 0.05).

Conclusion: The prevalence of dental caries among children below the age of 5 years in Imphal was high. The risk factors for ECC included age, low maternal education, improper feeding, and oral hygiene habits. However, the results revealed no significant relationship between ECC and BMI.
