The objective was to verify the electrical activity of the Mm. orbicularis oris and mentalis during
suction of different liquids in breastfed and non-breastfed children from 2.5-3.5 years old. It was used a signal conditioner (MCS-V2-Lynx Eletrônica Ltda, SP, BR) and Beckman Ag-AgCl bipolar surface electrodes. Breastfed children presented higher activity for mentalis and smaller values for the M. orbicular oris than non-breastfed children, suggesting the existence of different profiles of muscle activation between them.
