Background and Aim: Screening environmental factors associated with occlusion, such as the type and duration of infant feeding, may help identify children at risk of occlusal abnormalities and support preventive interventions. This study aimed to investigate the association between the type and duration of feeding during infancy and dental occlusal patterns in children.
Materials and Methods: This descriptive cross-sectional study included 173 children aged 4–5 years who were referred to the Department of Pediatric Dentistry, Yazd Dental School, during the 2024–2025 academic year. Participants were selected by convenience sampling. Data on age, sex, type and duration of infant feeding, and family history of skeletal and maxillofacial problems were obtained from parents. Dental examinations were performed to assess occlusal relationships. Data were analyzed by SPSS25 and chi-square and Fisher’s exact tests.
Result: A statistically significant difference was found in overbite among breastfed, formula-fed, and combination-fed children (P=0.005). No statistically significant association was observed between the duration of breastfeeding and occlusal relationships (P>0.05). A family history of skeletal and maxillofacial problems was significantly associated with molar relationship (P=0.002), while a borderline association was observed with overjet (P=0.055).
Conclusion: The type of infant feeding was significantly associated with overbite, whereas the duration of breastfeeding was not significantly associated with the assessed occlusal relationships. A family history of skeletal and maxillofacial problems was significantly associated with molar relationship. These findings highlight the potential relevance of early feeding practices and familial factors in the assessment of occlusal development in children.
