The purpose of this systematic review was to analyze the available literature about the influence of breastfeeding in primary and mixed dentition on different types of malocclusions.
Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines were used to perform the present review. The following electronic databases were searched: Pubmed, Evidence-Based Medicine Reviews (EBMR), Embase, Cochrane Library, Medline, Web of Science and Ovid.
A primary research found a total of 279 articles. Two more papers were also considered from the gray literature. Two hundred sixty-three articles were excluded as they were deemed irrelevant on the basis of: duplicates, title, abstract, methods and/or irrelevant contents. Eighteen papers were selected and included in the qualitative analysis.
breastfeeding is a positive factor that seems to reduce the incidence of posterior crossbite, skeletal class II and distoclusion in primary and mixed dentition. A sort of positive relationship between months of breastfeeding and risk reduction seems to exist. More longitudinal research is needed to avoid bias in the results, with data collected prospectively on the months of exclusive breastfeeding, by means of specific questionnaires and successive clinical evaluation of the occlusal condition at the primary dentition, mixed dentition and permanent dentition stages.
本系统评价的目的是分析有关母乳喂养对乳牙期和混合牙列中不同类型错合畸形影响的现有文献。
本研究采用系统评价和荟萃分析报告的首选报告项目（PRISMA-P）指南进行。检索了以下电子数据库：PubMed、循证医学评论（EBMR）、Embase、Cochrane 图书馆、Medline、Web of Science 和 Ovid。
初步研究共发现 279 篇文章。从灰色文献中还考虑了另外两篇论文。基于：重复、标题、摘要、方法和/或不相关内容，将 263 篇文章排除在外。选择了 18 篇论文进行定性分析。
母乳喂养是一个积极的因素，似乎可以降低乳牙期和混合牙列中后牙反合、骨骼 II 类和远中错合的发生率。母乳喂养的月数与风险降低之间似乎存在某种正相关关系。需要更多的纵向研究来避免结果出现偏差，通过专门的问卷收集纯母乳喂养的月数，并通过对乳牙期、混合牙列期和恒牙期的咬合状况进行前瞻性数据收集和连续临床评估。
