Abstract

Purpose: Among oral conditions, tooth decay is the most common chronic childhood disease. Children's dental caries are influenced by several factors, among which diet is one of the most highlighted ones. The present study was conducted to examine the decayed, missing and filled teeth in primary dentition (dmft) and caries-free (CF) indexes as well as the impact of nutrition and demographic factors on oral health of 2- to 6-year-old children in Fars Province. Methods: A cross-sectional study was conducted on children aged 2–6 years old to evaluate dmft and CF indices according to the latest WHO standards as well as their demographic characteristics in 2018. A questionnaire was used for data collection. Results: A total of 2220 children were recruited. The mean dmft was 1.37 ± 2.69. The components of the dmft score included decay (1.23 ± 2.6), missing (0.03 ± 0.11) and filling (0.11 ± 0.7) in primary dentition, and the prevalence of caries-free children was 66.5%. The results showed that dmft had a significant positive relationship with breastfeeding termination time, maternal education level and maternal age. Birth weight, consumption of iron, vitamin A and D supplements, age at onset of complementary feeding and maternal occupation had no significant relationship with dmft. Conclusions: The tooth decay index of 2- to 6-year-old children in Fars Province is very different from WHO global standards. Therefore, educating mothers about the duration of breastfeeding is important to achieve standard values for the dental caries index. © 2022 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
