“…Currently, the knowledge about the importance of breastfeeding, both for the child and the mother, is very advanced. The decision of not breastfeeding brings consequences to health development (Amaral et al 2017). Breast suction during breastfeeding involves several muscles and this recruiting is related to oral and facial development, culminating in the correct development of these structures (Chen et al 2015).…”

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.

“…Poor perinatal health and pacifier use may be risk factors for malocclusion development in primary teeth. The long duration of breastfeeding is associated with better occlusal conditions in the children of adolescent mothers [21]. However, several studies have reported prolonged and unrestricted breastfeeding as a potential risk factor for primary tooth caries (ECC) [22,23].…”

Background: Primary dentition is a determinant for future permanent occlusion. Objective: This aimed to evaluate the prevalence of malocclusion and associated variables in the primary dentition among preschoolers in the city of Tbilisi, Georgia. Methods: A cross-sectional survey was conducted among kindergarten children aged 3–5 years. Orthodontic characteristics were assessed by one calibrated clinician (E.G). Questionnaires were given to parents to record associated variables like general health problems, functional changes, and the presence of non-nutritive sucking habits. Results: A total of 396 participants aged 3-5 were included in the study. The prevalence of malocclusion was 49.8%, without significant differences among genders. The prevalence of Class II malocclusion was 21.2%(±4.091), followed by a deep overbite, i.e, 10.7% (±3.14), crossbite, i.e, 7% (±2.561), anterior open bite, i.e, 6.9%, and Class III malocclusion, i.e, 1.6% (±1.513). A total of 41.5% of children with breathing problems had Class II and 13% had crossbite. Speech disorder in 46.8% of cases was associated with anterior open bite. Pacifier users had Class II in 22.5%, deep overbite in 12.2%, and open bite in 9.2% of cases. There was a high prevalence of anterior open bite (25.2%) in children with a thumb-sucking habit (RR=4.90). These data sets are statistically reliable (p < 0.05). Conclusion: Almost half of the evaluated preschoolers had malocclusion. The most frequent disorder was Class II. Malocclusion is associated with non-nutritive sucking habits and mouth breathing.

“…It seems that swallowing properly and chewing thoroughly, which are helpful in keeping the resting tongue and jaws in correct posture, prevented hunter-gatherers from developing long-face syndrome (Buschang et al 2013 ). The spread of that syndrome may have started early in industrialization with reduction of duration of breastfeeding (Amaral et al 2017 ) and weaning to liquid or near-liquid baby foods. There is evidence that extended breastfeeding reduces the chances of children having some types of malocclusion (Peres et al 2015 , Boronat-Catalá et al 2017 , Doğramacı et al 2017 ) or suffering obstructive sleep apnea.…”

Contemporary humans are living very different lives from those of their ancestors, and some of the changes have had serious consequences for health. Multiple chronic “diseases of civilization,” such as cardiovascular problems, cancers, ADHD, and dementias are prevalent, increasing morbidity rates. Stress, including the disruption of traditional sleep patterns by modern lifestyles, plays a prominent role in the etiology of these diseases, including obstructive sleep apnea. Surprisingly, jaw shrinkage since the agricultural revolution, leading to an epidemic of crooked teeth, a lack of adequate space for the last molars (wisdom teeth), and constricted airways, is a major cause of sleep-related stress. Despite claims that the cause of this jaw epidemic is somehow genetic, the speed with which human jaws have changed, especially in the last few centuries, is much too fast to be evolutionary. Correlation in time and space strongly suggests the symptoms are phenotypic responses to a vast natural experiment—rapid and dramatic modifications of human physical and cultural environments. The agricultural and industrial revolutions have produced smaller jaws and less-toned muscles of the face and oropharynx, which contribute to the serious health problems mentioned above. The mechanism of change, research and clinical trials suggest, lies in orofacial posture, the way people now hold their jaws when not voluntarily moving them in speaking or eating and especially when sleeping. The critical resting oral posture has been disrupted in societies no longer hunting and gathering. Virtually all aspects of how modern people function and rest are radically different from those of our ancestors. We also briefly discuss treatment of jaw symptoms and possible clinical cures for individuals, as well as changes in society that might lead to better care and, ultimately, prevention.
