To characterize the understanding of pediatrician about the recommendation of dentifrices during the first childhood, a broader look is needed attempting not only their effective knowledge, but also the potential knowledge available in the literature. The pediatrician is responsible, at first, for the control of dental caries. Contradictorily, the entity that guides the practices of pediatric primary assistance, i.e. the Brazilian Society of Pediatrics, still does not have a department devoted to oral health. The conduction of systematic reviews suggest the clinician the recommendation of tooth brushing with dentifrice since the eruption of the first tooth, although there is still controversy regarding the use fluoride dentifrice before the age of two years. From a survey conducted by the Brazilian Society of Pediatrics it was observed that 80% of the pediatricians declared to refer children to a dentist for the first session of preventive care during the first one year of life, which indicates a knowledge -and a pertinent moveconverging to the recommendations nowadays. The pediatrician and the dentist should establish on of the horizontal connections to provide the children the best available care, which focus and intensity will be based on the permanent evaluation of the risk for caries.
