“…But in deciduous dentition the facial dimensions did not correlate with muscle strength, corroborating the fact that masticatory muscle function and facial form interaction can occur later. 4,8,24 This study did not find association between facial morphology and malocclusion in deciduous dentition, agreeing with the findings of Katz et al 7 (2004). However, in the early mixed dentition, children with a higher AFH/FWB ratio were significantly more likely to have crossbite (Table 2).…”

“…Past studies showed asymmetry in masticatory muscle activity and thickness, 1 decrease in bite force magnitude, a smaller number of teeth in contact, 2 and asymmetric jaw motion and growth of the orofacial structures [3][4][5][6] in children with crossbite.…”

“…1,5 Furthermore, inadequate growth of craniofacial structures and dentofacial complex results from several genetic and environmental factors, for example oral breathing. 4 However, the correct diagnosis of oral breathing is controversial due to the definition criteria used, which are often subjective. The lack of straightforwardness of the exams may result in incorrect diagnostics and consequently in inadequate treatment.…”

Posterior crossbite may affect craniofacial growth and development. Thus, this study aimed to associate facial dimensions (by standardized frontal photographs) to masseter and anterior portion of the temporal muscle thickness (by ultrasonography) and maximal bilateral bite force in 49 children with deciduous and early mixed dentitions. They were distributed in four groups: deciduous-normal occlusion (DNO, n = 15), deciduous-crossbite (DCB, n = 10), mixed-normal occlusion (MNO, n = 13) and mixed-crossbite (MCB, n = 11). Anterior facial height (AFH), bizygomatic width (FWB), and intergonial width (FWI) were determined and associated with muscle thickness and bite force, applying Pearson's coefficients and multiple logistic regression, with age, gender, body weight and height as the covariates. FWB and FWI were correlated positively with the masseter thickness, whereas AFH/FWB and AFH/FWI ratios had negative correlation, except in the DNO group. The correlation between AFH/FWB and bite force in the MCB group was significantly negative. A higher AFH/FWB in MNO and MCB led to a significantly higher probability for functional crossbite development. In the studied sample, it was observed that children in the early mixed dentition with a long-face trend showed lower bite force and higher probability to present functional posterior crossbite, without significant influence of the covariates.

“…Nonetheless, the literature is in disagreement showing higher rates (66.3% and 77.7%) 28,7 , as well as lower ones (5% to 30%) [29][30][31][32][33] . These differences can be explained by the methodologies used in other investigations, especially in regards of the diagnostic criteria.…”

Breat hing represents one of the vital functions of the organism, and its unbalance causes some series of alterations in several organs and systems. Aim: Verify the influence of socio-economic and demographic factors in determining breathing patterns. Study design: cross-sectional. Materials and Methods: there were 143 students in the sample, with ages ranging from 9 and 10 years, from two schools, public and private, in the city of Recife, Pernambuco. Breathing patterns were established through two tests: Glatzel Plate (Steam) and water time in the mouth. Socio-economic factors were evaluated through questionnaires with nine questions each. Statistics were carried out by means of the ChiSquared test or Fisher's Exact test and the significance level used was of 5%. Results: Oral breathing prevalence was of 55.2%, higher among females (57.7%) and in public schools (67.2%).Lack of medical care (62%), less use of medications (56.6%), parents with educational levels lower than high school, divorced parents (66%), students that do not live with their parents (68.7%) and homes with only one room (72%), in all of those situations, oral breathing signs were more prevalent. Only school type had significant association with the breathing pattern. Conclusion: High levels of oral breathing without differences concerning gender and age. With the exception of school type, there was no association between breathing pattern and socio-economic factors.

“…3,4 However, these clinical signs have been queried, since not all individuals who presented them were predominantly mouth breathers, and this facial type could also be a congenital trait, not necessarily related to the breathing mode. 5,6 Muscle patterns and skeletal growth are influenced only slightly by the breathing mode, since they are genetically transmitted and the facial type could be a congenital trait. 7 Proffit and Fields 8 (2000) have also emphasized the strong correlation between breathing mode and craniofacial dimensions.…”

Transverse craniofacial dimensions in Angle Class II, Division 1 malocclusion according to breathing mode

et al. 2010

The aim of this longitudinal study was to assess the relation between the transverse craniofacial dimensions of subjects with Class II, Division 1 malocclusion and the breathing mode presented by them. Forty Angle Class II, Division 1 malocclusion subjects of both genders participated in the study, 23 of which were predominantly nose breathers and 17 were predominantly mouth breathers. The mean age ranged from 10 years and 9 months to 14 years -Age range 1; and from 13 years and 4 months to 16 years and 6 months -Age range 2. Measurements of six transverse craniofacial dimensions were performed in P-A teleradiographs: Total Sphenoid, Total Zygomatic, Total Nasal Cavity, Total Maxilla, Total Mastoid and Total Antegonion. The transversal craniofacial dimensions were measured and compared in both groups at age ranges 1 and 2. The longitudinal assessment of age ranges 1 and 2 showed that there was no statistically significant influence of the breathing mode on the craniofacial dimensions evaluated, or on the alteration of these dimensions. Breathing mode had no influence on craniofacial development in the sample studied.

Breathing mode influence in craniofacial development

Abstract: We concluded that mouth breathing children tend to have higher mandibular inclination and more vertical growth. These findings support the influence of the breathing mode in craniofacial development.
