Exploring de association between feeding habits, non-nutritive sucking habits, and malocclusions in the deciduous dentition

Background: This study aimed to explore the association between feeding habits, non-nutritive sucking habits, and malocclusions in deciduous dentition. Methods: A cross-sectional observational survey was carried out in 275 children aged 3 to 6 years and included clinical evaluations of malocclusions and structured interviews. Statistical significance for the association between feeding habits and the development of malocclusion was determined using chi-square and Fisher's exact tests. In addition, odds ratio (OR) calculations were used for intergroup comparisons. Controlling for confounders was adjusted by excluding children with non-nutritive sucking habits. Results: The results indicated that there were no significant relationships between exclusive breastfeeding or bottlefeeding and the presence of any type of malocclusion (p>0.05). There was also no significant association between breastfeeding or bottlefeeding duration and malocclusion (p>0.05). In addition, it was observed that exclusive breastfeeding had a protective effect and diminished the risk of acquiring non-nutritive sucking habits (p=0.001). Conclusions: There was no association between feeding habits and malocclusions in the deciduous dentition in this sample of children. Exclusive breastfeeding reduced the risk of acquiring non-nutritive sucking habits
