Breastfeeding, bottle feeding and risk of malocclusion in mixed and permanent dentitions: a systematic review

Abstract

The aim of the present study was to search for scientific evidence concerning the association between breastfeeding and bottle feeding and risk of malocclusion in mixed and permanent dentitions. An electronic search was performed in eight databases up to February 2015. Additionally, a gray literature search and hand searches of the reference lists of the selected studies were also carried out. There were no restrictions on language or on year of publication. The methodology of the included articles was evaluated using the Newcastle Ottawa scale. Out of the 817 identified citations, six studies fulfilled the eligibility criteria and were included in the systematic review. One study showed that children with mixed and permanent dentitions breastfed for more than 6 months presented greater mean protrusion of mandibular incisors and inclination of maxillary incisors compared with those breastfed for less than 6 months or those who were bottle-fed (p < 0.05). One study revealed that breastfeeding and bruxism were associated with Class II [OR = 3.14 (1.28 -7.66)] and Class III [OR = 2.78 (1.21 -6.36)] malocclusion in children with permanent dentition, while another study showed that an increase in breastfeeding duration was associated with a lower risk of malocclusion in children with both mixed and permanent dentitions (p < 0.001). Three studies did not report any significant association. Risk of bias was high in most selected articles. These findings do not support an association between breastfeeding and bottle feeding and the occurrence of malocclusion in mixed and permanent dentitions.

“…Abreu et al (2016) advertem sobre a pouca discussão existente na literatura, até o momento, enfocando as associações entre hábitos bucais e má-oclusão nas dentições mista e permanente. Em uma revisão sistemática recente envolvendo estudos epidemiológicos, os autores concluíram não ser possível evidenciar uma associação entre amamentação, uso da mamadeira e má-oclusão.…”

“…A maior persistência nos hábitos de sução não nutritivos está associada à má oclusão 24 . O uso de chupeta ortodôntica é preferível ao hábito de sucção do dedo, pois este é mais difícil de ser controlado pelos pais 18 .

“…No nosso estudo, mais da metade dos nossos entrevistados tiveram, em algum momento, o hábito de utilizar a mamadeira. Há estudos que não encontraram associação entre o uso de mamadeira e má oclusão17,18 , enquanto Moimaz et al19 citam esta asso-Sintomas referidos pelos respiradores bucais e nasais.…”
