| Summary: | Abstract The aim of this systematic review and meta-analysis was to examine the current evidence on the possible effects of breastfeeding on different malocclusion traits in primary and mixed dentition. A systematic search was made in three databases, using terms related to breastfeeding and malocclusion in primary and mixed dentition. Of the 31 articles that met the inclusion criteria and were included in the qualitative analysis, nine were included in the quantitative analysis. The quality of the 31 observational studies was moderate to high on the Newcastle-Ottawa Scale. It was found that the odds ratio for the risk of posterior crossbite was 3.76 (95% CI 2.01–7.03) on comparing children who had not been breastfed, with those breastfed for over six months, and rose to 8.78 (95% CI 1.67–46.1) when those not breastfed were compared to those breastfed for over twelve months. The odds ratio for class II malocclusion in children breastfed for up to six months compared to those breastfed for over six months was 1.25 (95% CI 1.01–1.55). Lastly, children who were breastfed for up to six months had an odds ratio of 1.73 (95% CI 1.35–2.22) for non-spaced dentition compared to those who were breastfed for over six months. |
