Abstract

Introduction: A healthy diet and proper eating habits in childhood promote optimal oral health. This study aimed to evaluate dental caries and its association with feeding patterns in children referred to Bushehr dental centers in 2022.
Materials and Methods: This cross-sectional study was conducted on 178 children who referred to Bushehr dental centers in 1401. The DMFT index and the Persian version of the Food Frequency Questionnaire were used to check the tooth decay and the food pattern of children, respectively. A hierarchical linear regression model was used to investigate the relationship between tooth decay and food patterns; in this way, the variables affecting caries were placed in four blocks of demographic factors, behavioral factors, socio-economic factors, and the amount of food intake, so that by adjusting the effect of the first three blocks, the effect of the block of food intake in predicting the indices of dmft, DMFT and the sum of them (DMFT+dmft) could be checked.
Results: The hierarchical linear regression results showed that in the final model, the value of the adjusted R2 for the DMFT, dmft indices and, the sum of them (DMFT+dmft) was 0.63, 0.98 and, 0.59, respectively. (p value < 0.001). Furthermore, the predictive role of the dietary pattern alone (R2 change) on DMFT, dmft, and DMFT+dmft indices was 0.30, 0.52 and, 0.45 respectively, which indicates a higher predictive role than behavioral, demographic and, socioeconomic factors.
Conclusion: The study found a confirmed relationship between tooth decay and feeding patterns. It was also observed that feeding patterns have the greatest impact on the decay of deciduous, permanent teeth, and both of them in children of this age group.  Demographic characteristics, socioeconomic status of the family, and behavioral characteristics were respectively in the next levels and played a lesser role in the deterioration of these indicators.
