Abstract
Although humans breathe naturally through the nostrils, mouth breathing in children has recently gathered attention. In this study, we hypothesized that tongue function and its related maxillofacial morphology would affect breathing in adolescence. To verify this hypothesis, we examined the association between breathing patterns, including mouth and nasal breathing; oral functions, including tongue motor function; and craniofacial morphology during adolescence, which has not been investigated till date. C3-H, which indicates the anteroposterior position of the hyoid bone in relation to the third cervical vertebra, was significantly smaller in mouth-breathers than in nasal-breathers. Lip-closing force, tongue pressure, and masticatory efficiency were lower in the order of nasal-breathers, oronasal-breathers, and mouth-breathers, and the values for mouth-breathers were significantly lower than those for nasal-breathers. Tongue pressure alone was identified as a significant independent variable, with an odds ratio of 1.063 (95% confidence interval, 1.006-1.123; p < 0.05). Our results indicate a relationship between mouth breathing and the lip-closing force, tongue pressure, and masticatory efficiency, as well as the significance of tongue pressure on mouth breathing in adolescents. The findings highlight the importance of clarifying the pathophysiology of mouth breathing and its underlying causes.

Abstract
OBJECTIVE Childhood is an important period for lip-closing strength (LCS) development, and failure to acquire LCS during childhood leads to various adverse health effects, such as mouth breathing. The purpose of this study was to examine the effectiveness of device-free lip and facial training in preschool children. DESIGN The participants were divided into training and control groups. Both groups comprised 123 children aged 3-4 years, and only the training group received lip and facial training (i.e., opening and closing the lips and protruding the tongue) for 1 year. A two-way repeated measures analysis of variance was applied to compare the interaction effects of LCS and facial linear distance and angle by year (initial year vs. 1 year later) and group (training vs. control group). In addition, paired t-tests were used to test the changes in LCS and facial linear distance and angle after 1 year in both groups. Furthermore, the same analysis was performed in children with weak LCS in both groups (incompetent lip seal [ILS]). RESULTS The LCS of children in the training group significantly increased after training compared with that in the control group, whether the analysis included all children or children with ILS alone. Lip and facial training for children with ILS reduced both the upper and lower lip protrusion; children with ILS without training had increased lip protrusion after 1 year. CONCLUSIONS Lip and facial training for children with ILS effectively improved LCS and lip morphology, thereby preventing increased lip protrusion.

Abstract
PURPOSE mouth breathing (MB) has detrimental effects on children's growth. Diagnosis of MB is possible through a multidisciplinary approach including Speech-Language Pathologist's (SLP) assessment; however, SLPs currently have little to no defined selection criteria to determine the awake and habitual breathing pattern. This study aims at identifying relevant criteria for the assessment of the habitual and awake breathing pattern of preschool children, and developing a grid that would help SLPs diagnose MB in their clinical practice. METHODS A three-rounded online international Delphi process was conducted to achieve a consensus on the relevant items and their interpretation. Agreement was established through a Content Validity Ratio calculation. Based on the agreed items, we developed a grid through a scoring function. RESULTS Observing the child at rest (i.e., time spent with an open/closed mouth and position of the tongue/lips) was considered the most important criterion. The experts also considered that observing the breathing pattern while chewing (open/closed mouth) and after swallowing (i.e., air intake and open/ closed mouth just after swallowing) should provide relevant but secondary information in decision-making. We were able to establish a clinical grid based on those criteria. CONCLUSION The Delphi procedure provided content-valid criteria and conditions of observation for the myofunctional SLP assessment of the awake and habitual breathing pattern in preschoolers. A clinical validation of the developed prototype grid should be conducted in preschool children to explore its effectiveness in the diagnosis of MB.

Abstract
OBJECTIVES A set of orofacial signs and symptoms completely or partially present in individuals who replace the correct pattern of nasal breathing with an oral or mixed pattern is defined as mouth breathing syndrome (MBS). In a previous report, it was clarified that an incompetent lip seal (ILS) affected the occurrence of MBS among primary school children. However, the factors related to MBS and the effect of ILS in preschool children remain unclear. The purpose of this study was to clarify the factors relevant to MBS in preschool children and investigate the relationship of ILS to MBS. MATERIAL AND METHODS We surveyed 285 preschool children between 3 and 5 years of age. Their guardians completed the questionnaire, which consisted of 44 questions regarding the children's daily health conditions and lifestyle habits. To classify the closely related questions into their respective factors and to examine the strength of the correlation between the newly revealed factors, an exploratory factor analysis with promax rotation was performed. RESULTS The factor analysis identified nine items representing four factors. Factors 1-4 were defined as "diseases of the nose," "ILS," "problem with swallowing and chewing," and "eating and drinking habits," respectively. Factor 2 most strongly correlated with Factor 1, and both Factors showed a relatively strong correlation with Factor 3. CONCLUSIONS The initial stage of MBS may be present in preschool children. ILS and diseases of the nose can cause poor development of oral functions, such as breathing and eating.

Abstract
This study aimed to highlight the perceived associations between general and oral pathology, among clinicians of different specialties. Data was collected through a questionnaire with 22 questions, with single or multiple answers, to 88 dentists, general practitioners, or pediatricians. The majority of participants were women (89.8%), aged between 30 and 39 years (52.3%), with a professional experience mostly under 10 years (61.3%). Many doctors considered that there was an association between oral and general pathologies (39.8%). The most common general pathologies associated with oral pathology were digestive disorders (n=21, 23.9%), followed by cardiovascular, genetic, endocrine and metabolic, neuropsychiatric, respiratory, hematological, immunological, and oncological pathologies. Tooth decay was mainly found in patients with digestive, respiratory, or neuropsychiatric disorders, and periodontal disease was more common in patients with obstetric disorders. Diseases of the oral mucosa, such as canker sores and gingivostomatitis, were more common in patients with digestive pathology, endocrine and metabolic, or reproductive disorders. The study pointed out that physicians, regardless of their medical training, often observed a relatively rich general pathology associated with oral conditions. It is important to differentiate between primary and secondary oral pathology, associated with general pathology and medication, establishing a correct diagnosis of the disease and treatment according to general or oral diseases and their manifestations.

Abstract
Cardio-facio-cutaneous syndrome 3 (CFC3) due to variants in MAP2K1 is a rare genetic disorder manifested mainly by short stature, facial dysmorphism, abnormalities of the cardiovascular system, skin changes, and intellectual disability. The aim of the study is the evaluation of the occurrence of pathological changes in the upper respiratory tract, orthodontic disorders, as well as voice, speech and hearing abnormalities in an 11-year-old boy with CFC3 syndrome. The lack of detailed diagnostics of speech, voice and hearing disorders, as well as the degree of their severity was an inspiration to undertake research in this field. Pathological changes in face, oral cavity, upper respiratory tract (nose, nasopharynx, larynx), and hearing organ, as well as voice and speech quality, were assessed in an 11-year-old boy with CFC3 syndrome. Pathologies of the upper respiratory tract (adenoid hypertrophy, narrowing of the nasal passages) and laryngeal asymmetry were found without significant changes in voice quality in the acoustic examination, except for the voice timbre change confirmed in narrowband spectrography. Complex audiological assessment confirmed the existence of bilateral sensorineural hearing loss. Speech pathology assessment revealed abnormalities in the structure of articulation organ, its decreased motor efficiency, imprecision, reduced coordination, as well as the presence of autistic features. Exome sequencing showed the heterozygous variant c.371C>T (p.Pro124Leu) in the MAP2K1 gene, previously described as pathogenic, thus supporting a causative relevance. Phoniatric, audiological, orodental and speech problems should be considered as features of cardio-facio-cutaneous syndrome type 3 (CFC 3) phenotype due to a pathogenic variant in MAP2K1.

Abstract
Objectives Weakening of lip‐closing strength (LCS) associated with an incompetent lip seal (ILS) may affect the oral balance between the lip and tongue pressures. The purpose of this study was to evaluate the effects of lip‐closing training in children with lower LCS and/or abnormal habits across different age groups and to compare its effects on increasing LCS in children with malocclusion and/or oral habits. Material and Methods Lip‐closing training was performed by 154 Japanese children aged 3–12 years using a specialized training device at home for 3 months. Children with oral habits and/or exhibiting less than standard LCS were included. LCS was measured using a digital strain force gauge at a dental clinic at the beginning (T0) and after each month (after 3 months: T3). Results Children had higher LCS responses after lip‐closing training. The first month of lip‐closing training was more effective than the subsequent months. With lip‐closing training, the LCS increased from an average of 6.2 N (T0) to 11.4 N (T3) in Group I, 7.9 N (T0) to 12.8 N (T3) in Group II, and 6.8 N to 11.4 N in Group III. Anterior cross bite, including reverse bite, open bite, and tongue thrusting, significantly reduced training effects. Conclusion Our findings showed that lower LCS in children with ILS resulted in greater responses to lip‐closing training in a short period, but oral dysfunction, such as abnormal habits, inhibited the positive effects of training. Our results suggest that less detrimental effects of malocclusion and abnormal oral habits lip‐closing training enhances LCS in younger children.

Electromyographic features and efficacy of orofacial myofunctional treatment for skeletal anterior open bite in adolescents: an exploratory study. BMC Oral Health 2021; 21:242. [PMID: 33962610 PMCID: PMC8103572 DOI: 10.1186/s12903-021-01605-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2021] [Accepted: 04/28/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Due to the multifactorial aetiology and unpredictable long-term stability, skeletal anterior open bite (SAOB) is one of the most intractable conditions for orthodontists. The abnormal orofacial myofunctional status (OMS) may be a major risk factor contributing to the development and relapse of SAOB. This study is aimed at evaluating the OMS and the efficacy of orofacial myofunctional therapy (OMT) alone for SAOB subjects. METHODS Eighteen adolescents with SAOB (4 males, 14 females; age: 12-18 years) and eighteen adolescents with normal occlusion (2 males, 16 females; age: 12-18 years) were selected. The electromyographic activity (EMGA) associated with mastication and closed mouth state was measured. Lateral cephalography was used to evaluate craniofacial morphology. Wilcoxon signed rank tests and t-tests were performed to evaluate myofunctional and morphological differences. Pearson or Spearman correlation analysis was used to investigate the correlations between EMGA and morphological characteristics. SAOB subjects were given OMT for 3 months, and the EMGA was compared between before and after OMT. RESULTS During rest, anterior temporalis activity (TAA) and mentalis muscle activity (MEA) increased in SAOB subjects, but TAA and masseter muscle activity (MMA) decreased in the intercuspal position (ICP); and upper orbicularis activity (UOA) and MEA significantly increased during lip sealing and swallowing (P < 0.05). Morphological evaluation revealed increases in the FMA, GoGn-SN, ANS-Me, N-Me, L1-MP, U6-PP, and L6-MP and decreases in the angle of the axis of the upper and lower central incisors and OB in SAOB subjects (P < 0.05). TAA, MMA and anterior digastric activity (DAA) in the ICP were negatively correlated with vertical height and positively correlated to incisor protrusion. MEA was positively correlated with vertical height and negatively correlated with incisor protrusion; and the UOA showed a similar correlation in ICP, during sealing lip and swallowing. After SAOB subjects received OMT, MEA during rest and TAA, MMA and DAA in the ICP increased, while UOA and MEA decreased (P < 0.05). CONCLUSION SAOB subjects showed abnormal OMS features including aberrant swallowing patterns and weak masticatory muscles, which were interrelated with the craniofacial dysmorphology features including a greater anterior facial height and incisor protrusion. Furthermore, OMT contributes to OMS harmonization, indicating its therapeutic prospect in SAOB.

Abstract
OBJECTIVE Determine the association between breastfeeding and the development of mouth breathing in children. MATERIALS AND METHODS Seven databases were searched for studies investigating the association between the type of feeding and the development of the breathing pattern in children. Descriptive analysis and meta-analysis were performed, with the calculation of the prevalence and likelihood (odds ratios (95% CI)) of mouth breathing according to the duration of breastfeeding. RESULTS The overall prevalence of mouth breathing was 44% (95% CI: 38-49) (N total = 1182). Breastfeeding was a protection factor against the development of mouth breathing (OR = 0.62; 95% CI: 0.41-0.93). The likelihood of developing mouth breathing was 41% and 34% lower among children that were breastfed for more than 12 and more than 24 months, respectively. No association was found between exclusive breastfeeding for up to 6 months and the occurrence of mouth breathing (OR = 0.60; 95% CI: 0.31-1.18). CONCLUSIONS Due to the scarcity of cohort studies that met the inclusion criteria and the low certainty of the evidence, no strong evidence-based conclusion can be drawn. However, breastfeeding should be encouraged due to its possible protective effect, evidenced by the substantial reduction in the prevalence of mouth breathing pattern when performed for up to 2 years. Exclusive breastfeeding was not associated with the development of the breathing pattern. CLINICAL RELEVANCE The results reveal that breastfeeding can protect children from the development of mouth breathing. Thus, healthcare providers should offer support so that mothers feel prepared and encouraged to perform breastfeeding. TRIAL REGISTRATION PROSPERO registry: CRD42017062172.

Prevalence of an incompetent lip seal during growth periods throughout Japan: a large-scale, survey-based, cross-sectional study. Environ Health Prev Med 2021; 26:11. [PMID: 33478389 PMCID: PMC7819306 DOI: 10.1186/s12199-021-00933-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2020] [Accepted: 01/07/2021] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Systemic and local factors may lead to disruption of craniofacial growth and development, causing an imbalance between the orofacial skeleton, muscle and soft tissue, dental occlusion, and the dental arch during growth periods. We aimed to reveal whether the prevalence of incompetent lip seal (ILS) varies with age and region, as well as to clarify the factors related to an ILS, in a national, large-scale epidemiological study. METHODS We surveyed 3399 children, from 3 to 12 years of age, visiting 66 pediatric dental clinics throughout Japan. For this survey, we employed a questionnaire consisting of 44 questions regarding daily health conditions and lifestyle habits. We evaluated the differences in ILS prevalence by age and region (using a Cochran-Armitage test for trend and a Kruskal-Wallis test), and the relationship between ILS and factors investigated in the questionnaire (using Spearman's rank correlation coefficient). RESULTS We observed that 30.7% of Japanese children exhibited an ILS and that the ILS rate increased with age (p < 0.001). There were no regional differences in the rate of ILS in Japanese children (p = 0.506). We revealed that 12 of 44 survey items exhibited a statistically significant correlation with ILS (p < 0.001), using Spearman's rank correlation coefficient. These items involved orofacial morphology, mouth breathing, and possibly, allergic rhinitis. CONCLUSION The rate of ILS seems to increase with age in children, throughout Japan. Therefore, this disorder may not self-correct during the growth periods in these children. Guidelines are required for pediatric dentists to recognize ILS among children aged 3-12 years.

Abstract
BACKGROUND Severe intractable tics, which are associated with Tourette syndrome and chronic tic disorder (TS/CTD), severely affect the quality of life. Common less-invasive treatments are often unable to attenuate tics with deep brain stimulation currently being the only effective treatment. We aimed to assess the anti-tic effect of deep slow nasal respiration with tight lip closure using patients with TS/CTD. METHODS We retrospectively analyzed 10 consecutive patients (9 men, 1 woman; 23-41 years old). We instructed the patients to perform the procedure for 120 s and to obtain a video recording of before and during the procedure. The videos were used to count tics and determine lip competency or incompetency. The counted tics were rated using the modified Rush Video Rating Scale. RESULTS Compared with before the procedure, there were significantly lower frequencies of motor and phonic tics, as well as video scored, during the procedure. Eight patients presented with lip incompetency before the procedure and none after the procedure (P = 0.041). There were no side effects associated with the procedure. CONCLUSION Our findings indicate that deep slow nasal respiration with tight lip closure ameliorates tics in patients with TS/CTD. In accordance with our results, lip opening and oral breathing could be causes of tics, in addition to heritability. Therefore, this novel procedure could improve tics. Furthermore, our findings could contribute toward the development of tic treatments and elucidate their pathophysiology regarding the reward system, hypersensitivity, autonomic nerves, and nasal airway.

Abstract
ABSTRACT Purpose: to analyze the auditory behavior and the performance in the Sustained Auditory Attention Ability Test (SAAAT) of children with different breathing modes. Methods: a total of 30 individuals (19 males and 11 females), ranging from seven to 11 years old, participated in the research. They were distributed into nasal-breathers, mouth-breathers, and oronasal-breathers groups. The Scale of Auditory Behaviors (SAB) questionnaire was applied to those responsible for the children, so as to characterize their auditory behavior. In the SAAAT, the following error patterns were analyzed: inattention, decreased vigilance, impulsivity, and total errors. For the inferential analysis, the Mann-Whitney, chi-square, and Kruskal-Wallis statistical tests were used. Results: the individuals with mouth- and oronasal-breathing modes had more complaints in the SAB questionnaire when compared with nasal-breathers. Regarding the SAAAT, it was found that the age group of seven to eight years was the one that had the worst performance in the test. The groups with oral and oronasal breathing had more errors, with a statistically significant difference between the groups for inattention and total errors. Conclusion: it can be concluded that individuals with oral and oronasal breathing had more complaints in the auditory behavior and worse performance in the SAAAT, especially for inattention and total errors.
