RESUMO
AIM: This study aimed to investigate the associations between breastfeeding, nonnutritive sucking habits (NNSHs), and malocclusion in deciduous, mixed, and permanent dentition. MATERIALS AND METHODS: A sample of 50 children between 3 and 12 years, enrolled in a pediatric dentistry dental care program, underwent orthodontic examination for detection of occlusal patterns and malocclusion. In addition, data regarding breastfeeding duration and NNSH acquisition were obtained from standardized questionnaires responded by the children's parents or legal guardians. RESULTS: Regardless of a long period of breastfeeding, a high incidence of NNSH in the evaluated sample was observed. Nevertheless, the presence of NNSHs was not significantly associated with malocclusion. CONCLUSION: The findings could not indicate a statistically significant association between breastfeeding duration, acquisition of NNSHs, and malocclusion. Longitudinal studies with larger samples are still needed to better support clinical decisions.How to cite this article: Roscoe MG, da Silva Bonifacio SV, da Silva TB, Pingueiro JMS, Lemos MM, Feres MFN.
