Introduction: The habit of pacifier sucking stands out as one of the most prevalent among non-nutritive sucking habits, especially in the early years of an individual's life. According to the AAPD, this habit should be discontinued by the age of two, at most three years old. Otherwise, there is a high probability of developing malocclusions, such as anterior open bites, posterior crossbites, increased overjet, Class II canine, and distal step of the deciduous second molar. Objectives: This systematic review aimed to assess the differences in malocclusions resulting from prolonged use of orthodontic or conventional pacifiers in children up to five years old, considering the duration and frequency of use. Material and methods: To address the research question and conduct this systematic review, the following databases were utilized: Web of Science®, Scielo®, ScienceDirect®, Scopus®, anda PubMed/MEDLINE®. Inclusion criteria, keywords, and synonyms were established to construct search strings. Using the keywords, search strings were developed using the boolean operators "OR" and "AND" in each database. Results: Four studies were included, and the following relevant data were extracted: author, date, and country of the study; type of research conducted; publishing journal; age range; number of children without pacifier sucking habit; total casuistic; methodology; total number of children with orthodontic and conventional pacifier sucking habit; frequency and duration of use for both types of pacifiers; quantity and measurements of malocclusions and main conclusions obtained. Conclusion: Children with pacifier sucking habits have an increased risk of developing malocclusions, regardless of the type of pacifier used. It was not possible to conclude which type of pacifier is more beneficial for the child's oral cavity.
