More than 530 million children have caries lesions in deciduous teeth, about half of the world's pediatric population. Caries disease inflicts a high financial burden on society because of its enormous prevalence. The best treatment is prevention, and since brushing is the primary method of preventing dental caries, it is important to use an appropriate and effective toothbrush to remove plaque. Objectives: To gather and analyze all the information in the literature that, comparing a manual toothbrush with an electric toothbrush, assess the effectiveness of plaque removal in the pediatric population, with the purpose of adapting the best prevention method to the needs of the individual and the parent/caregiver. Materials and Methods: This study was developed according to the current PRISMA Guidelines and Checklists (Preferred Reporting Items for Systematic reviews and Meta-Analyses). Based on the research question (PICO) and the objectives defined previously, strategies for data collection were established. "When comparing brushing (I), of a manual brush with an electric brush (C), which is more effective in removing plaque (O), in the pediatric population (P)?" Results: Through the initial search, with the search terms and equations, 568 articles were identified, distributed as follows: 305 in PubMed/Medline, 152 in Cochrane Library, and 111 in Sci-Elo. From these, by the process of inclusion and exclusion, 7 articles were selected for full reading. Conclusion: 6 articles stated that brushing with an electric toothbrush is more effective than manual brushing. This statement covers both the deciduous and mixed dentition, regardless of who performs the brushing.
