Associação do aleitamento materno e desenvolvimento da oclusão decídua: uma revisão de literatura

Abstract

The aim of this study was to identify evidence in the literature of an association between breastfeeding and the development of occlusion in the deciduous dentition, through a literature review. Articles on the following were included: 1. The association between breastfeeding duration and the development of deciduous occlusion. 2. The association between breastfeeding duration and the development of deciduous occlusion. Articles that did not address the topic, as well as literature reviews, animal studies, and in vitro studies, were excluded. The databases consulted in March 2025 were: MEDLINE (PUBMED) and Virtual Health Library (BVS). No filters were used. There were no language limitations in the search. After removing duplicates, a total of 266 articles were retrieved, of which 142 were selected by title and 83 by abstract. Finally, 11 studies were selected for review. The studies were published between 2000 and 2020, including 10 cross-sectional studies and 1 cohort study conducted in Argentina, Brazil, China, Cuba, Spain, the United States of America, Japan, Mexico, Norway, Puerto Rico, Sweden, and Turkey. The most frequently observed malocclusions were anterior open bite (AOB), posterior crossbite (PCB), distoclusion, and anterior crossbite (ACB). The studies included in this review reinforce the hypothesis of an association between exclusive breastfeeding and the development of deciduous occlusion. However, more observational studies are needed to better elucidate the influence of exclusive breastfeeding on the development of deciduous occlusion.
