“…Additionally, nasal breathing allows for the tongue to remain inside the oral cavity and in contact with the palate, which exerts an expansive force within the oral cavity that opposes the inwardly directed forces of the buccinator muscle (1) . Chronic mouth breathing, or mixed pattern, is used as a substitution for the nasal breathing pattern, resulting in functional, structural, postural, and biomechanical changes that additionally interfere with the lip seal closure (2,3,4,5,6,7) . The main changes occur in the craniofacial morphology (1) .…”

“…Nasal obstruction can be caused by upper airway obstruction, such as the incidence of septal deviation, malformation, inflammation of the nasal mucosa (rhinitis), or hypertrophy of the Waldeyer's ring (4) . The main causes of mouth breathing in children are allergic rhinitis, incidence of hypertrophic adenoids and/or tonsils, developed habits, and related obstructive diseases.…”

“…During standard adolescent development, pharyngeal and palatine tonsils undergo an involution process. However, if mouth breathing patterns are left untreated during childhood, the changes occurring during adolescence it may hinder normal development and dental-craniofacial growth (4,5) . Changes to the stomatognathic system can be clinically analyzed via several objective and subjective methods with tools and pre-tested protocols for use with children (11) .…”

Purpose: To investigate the influence of mouth breathing on the maximum molar bite force in children. Methods: One hundred and five children were divided into two groups: the control group (CG) without respiratory symptoms and the clinical pattern of a competent lip seal, and the mouth breathers (MB) who had respiratory complaints and an otorhinolaryngological diagnosis of nasal obstruction. All participants were assessed for their maximum isometric bite force (MIBF), on both sides of the dental arch, with a gnathodynamometer positioned in the region of the first molars. Paired and unpaired Student's t-tests were used in the comparisons of the MIBF of both sides from each group and between each group (CG and MB). The degree of obstruction was correlated with MIBF (MB), using the Spearman correlation test. Results with p≤0.05 were considered significant. Results: There were no significant differences in the MIBF values between the right and left sides of the dental arch. In a comparison of the MIBF values of the CG and MB participants, no difference between the groups were found in general. However, when the age of the survey participants was correlated against MIBF, an increase in MIBF value according to age was evident for the CG participants. Conclusion: Nasal obstruction did not influence maximum isometric bite force in children between three and 12 years old. There was no correlation between the degree of obstruction and the bite force. The CG bite force was higher for older children, however, this correlation was not observed in MB.Keywords: Bite force; Mouth breathing; Child; Nasal obstruction; Dentition, Mixed RESUMO Objetivo: Investigar a influência da respiração bucal na força de mordida máxima de dentes molares em crianças. Métodos: Cento e cinco crianças foram divididas em dois grupos: grupo controle (GC), sem queixas respiratórias e com padrão clínico de vedamento labial e grupo de respiradores bucais (GRB), com queixas respiratórias e diagnóstico otorrinolaringológico de obstrução nasal. Todos os participantes realizaram a avaliação da força de mordida isométrica máxima (FMIM), de ambos os lados da arcada dentária, por meio de um gnatodinamômetro posicionado na região dos primeiros molares. Os testes estatísticos t de Student pareado e não pareado foram usados nas comparações da FMIM entre os lados, de cada grupo, e entre os grupos (GC e GRB). O grau de obstrução foi correlacionado à FMIM (GRB), por meio do teste de correlação de Spearman. Foram considerados significativos resultados com p≤0,05. Resultados: Não houve diferença nos valores de FMIM entre os lados direito e esquerdo da arcada dentária. Quando comparados os valores de FMIM dos participantes do GC e do GRB não foi observada diferença, de um modo geral. Entretanto, quando correlacionada a FMIM com a idade dos participantes da pesquisa, notou-se que no GC houve aumento no valor da FMIM, de acordo com a idade. Conclusão: A obstrução nasal não influenciou na força de mordida isométrica máxima em crianças de 3 a 12 anos de idade. Não ...

ImportanceObstructive sleep apnea (OSA) and tonsil hypertrophy may be associated with dysphagia. However, randomized clinical trials assessing dysphagia outcomes in children randomized to adenotonsillectomy (AT) vs watchful waiting with supportive care (WWSC) are lacking.ObjectiveTo assess dysphagia outcomes in children with OSA and tonsil hypertrophy managed with AT or WWSC.Design, Setting, and ParticipantsThis secondary analysis of a multicenter randomized clinical trial, the Childhood Adenotonsillectomy Trial (CHAT), was conducted at tertiary children’s hospitals from October 2007 to June 2012. Children aged 5.0 to 9.9 years with OSA were randomized to AT or WWSC and underwent polysomnography at baseline and 7 months. Caregivers completed the OSA-18 questionnaire, which includes an item on difficulty in swallowing at baseline and 7 months. The current secondary analysis was conducted from December 1, 2022, to January 10, 2023.InterventionsAT vs WWSC.Main Outcomes and MeasuresPrevalence of dysphagia, based on parental responses to the difficulty in swallowing item on the OSA-18 questionnaire, was redefined as a binary outcome at baseline and 7-month follow-up.ResultsIn total, 386 children were included (199 female [51.6%]; median [IQR] age, 6.0 [5.0-8.0] years). Of the total, 207 children were Black (53.6%). At baseline, the number of children with dysphagia was similar (4.0%; 95% CI, −4.9% to 12.9%) between the AT group (56 [29.8%]) and the WWSC group (51 [25.8%]). Following AT, a decrease was observed (21.3%; 95% CI, 13.5%-28.9%) in the prevalence of dysphagia among the children. In contrast, the prevalence of dysphagia did not change significantly (1.0%; 95% CI, −7.6% to 9.6%) in the WWSC group. Children in the AT group were more likely to experience a resolution of dysphagia than those in the WWSC group (adjusted odds ratio, 4.84; 95% CI, 1.91-12.25). Higher baseline AHI was associated with a lower resolution of dysphagia (AOR, 0.91; 95% CI, 0.83-0.98).Conclusions and RelevanceThis secondary analysis of the CHAT randomized clinical trial suggested that children with dysphagia and OSA undergoing AT may experience dysphagia improvement. A prospective randomized trial that uses a validated dysphagia survey is needed to verify the effectiveness of AT in treating dysphagia.Trial registrationClinicalTrials.gov Identifier: NCT00560859
