Nutritional and non-nutritional habits and occurrence of malocclusions in the mixed dentition

Abstract

Malocclusions are changes in the development of craniofacial structures of high prevalence. Associated risk factors are diverse and nutritional and non-nutritional suction habits are the most reported. The aim of this study was to estimate the prevalence of malocclusions in the mixed dentition and to study possible association with practices of breastfeeding and suction habits among Brazilian schoolchildren. A cross-sectional study involving a sample of 664 6-year-old children and their families was carried out. Data collection was done through interviews with mothers in the homes and oral examinations of children in schools. Multivariate analyses were performed using the Poisson regression with a robust estimator. The prevalence of overjet over 4 mm was 21.1% and of posterior crossbite was 12.2%; 91.9% of the children were breastfed, 79.0% used a nursing bottle and 49.4% used a pacifier. Significant and independent associations were observed between father's unemployment, private school, interruption of breastfeeding before the fourth month and pacifier use with certain malocclusions. High rates of malocclusion were found in the studied sample. Socioeconomic conditions, breastfeeding practices and suction habits were shown to be statistically associated with their occurrence.

Frequency and Predictors of Pacifier Use in the Low Socioeconomic Group of Karachi, Pakistan: A Cross-Sectional Study

“…Women not using pacifiers in our study amounted up to 51% of the participants with most of them chalking it to be a bad practice (30%), or pacifiers being unhygienic and unhealthy (27%) for their child. This can be corroborated by the survey of Traebert et al where dental malocclusions, including the presence of class II or III molar/canine relationship, posterior crossbite, and anterior open bite were significantly associated with pacifier use [ 23 ]. In another report, emergency room visits of an estimated 45,398 children under three years of age were linked to pacifiers (19.9%) [ 24 ].…”

Ineffective Feeding Practices and Their Effect on Malocclusion: A Narrative Review

“…Preventive and interceptive orthodontics has been a subject of continuous dispute with respect to treatment timing, fruitfulness, physiological, and psychological benefits. 29 For the enhancement of dental and skeletal development, it has been advised to initiate an early intervention. This not only aids to facilitate the correction of habits, improper functions, and malocclusions in their early stages, but also the compromised transverse dimensions that can cause temporo mandibular joint problems or facial asymmetry.…”

“…This not only aids to facilitate the correction of habits, improper functions, and malocclusions in their early stages, but also the compromised transverse dimensions that can cause temporo mandibular joint problems or facial asymmetry. 29 Thus, breastfeeding, although a boon, comes with its checklist of cautions. To minimize the effects of ineffective breastfeeding it is important to raise awareness about EBF.…”

Efetividade do tratamento ortodôntico interceptativo com aparelho removível em crianças com mordida cruzada e mordida aberta na fase de dentadura mista

“…Maloclusão é um termo utilizado na odontologia para definir alterações no desenvolvimento craniofacial, envolvendo ossos, línguas e músculos, podendo ocasionar deformidades faciais e alterações de natureza funcional e estética, comprometendo a qualidade de vida dos acometidos (Traebert, Zanini, Nunes & Traebert, 2020). Dentre as maloclusões que se destacam na dentição decídua e mista cita-se em especial as mordidas cruzadas (Pompei, 2005) e mordidas abertas (Sousa, Taveira & Almeida, 2004).…”
