Discussão: A comparação entre os grupos demonstrou que as crianças com rinite alérgica e respiração oral apresentam maior altura facial inferior, maior ângulo entre o plano de Frankfurt e o plano mandibular e maior ângulo entre a linha Sela-Nasion e o plano oclusal. Este grupo apresentou também menor comprimento da maxila e da mandíbula, menor overbite e diminuição do espaço aéreo respiratório superior. Conclusões: As crianças com rinite alérgica e respiração oral têm faces mais longas, maxilas e mandíbulas mais curtas e espaço aéreo faríngeo menor. Não existem diferenças estatísticas significativas entre grupos nas bases ósseas (plano sagital) ou inclinações dentárias. Palavras-chave: Cefalometria; Criança; Portugal; Respiração Oral, Rinite Alérgica. ABSTRACT Introduction:Orthodontists frequently treat children with mouth breathing. The purpose of the present study was to examine dental positions, skeletal effects and the pharyngeal airway space of children with chronic allergic rhinitis, when compared with a control group exhibiting a normal breathing pattern. Comparison between the allergic rhinitis and control group showed that there is an increased lower facial height, larger Frankfurt -mandibular plane angle and Sela-Nasion oclusal plane angle in children with chronic allergic rhinitis. This group also had a shorter maxillary and mandibular length, less overbite and decreased upper airway space. Conclusions: Children with allergic rhinitis and mouth breathing have longer faces, shorter maxillas and mandibles and a narrowed pharyngeal airway space. No statistical differences between the groups in sagital relationships or in dental inclinations were found.

“…The impact caused by upper airway obstruction results in changes in facial growth 2 ; posture, including lips and tongue 4 ; architecture and morphology of the maxilla 3 , hard palate 5 , and mandible 6 ; and consequently, in dental occlusion [7][8][9][10][11][12] , justifying the interest and need for intervention in altered respiratory mode by several health professionals such as speech-language pathologists, physiotherapists, and dental surgeons, in partnership with otorhinolaryngologists and pediatricians.…”

ResumoIntrodução: Diversos fatores podem interferir no tratamento ortodôntico, sendo importante verificar quais podem prejudicar o seu sucesso. Objetivo: Comparar a duração do tratamento ortodôntico entre respiradores orais e nasais em indivíduos com má oclusão de Angle Classe II, divisão 1. Material e método: Trata-se de um estudo observacional analítico, que utilizou prontuários de pacientes ortodônticos, compreendendo o período de 1999 a 2009, de uma Instituição de Ensino Superior do Estado de São Paulo. Os dados foram analisados pelas variáveis: idade, sexo, modo respiratório (oral ou nasal) e tempo de tratamento (inicial e final). Os pacientes foram pareados por idade e pelo tratamento utilizado. Para a análise dos dados utilizou-se o teste ANOVA (p<0,05). Resultado: A amostra foi composta por 36 indivíduos, sendo 16 do sexo feminino (10 respiradores nasais e 6 orais) e 20 do masculino (8 respiradores nasais e 12 orais), com idades entre nove e 15 anos (média:13,02). Quanto ao tempo de tratamento ortodôntico, os respiradores nasais permaneceram entre 27 e 74 meses (média 39,61) e os orais entre 29 e 50 meses (média 36,66), sem diferenças estatisticamente significativas entre os grupos de estudo. Conclusão: O modo respiratório alterado não foi uma variável que interferiu no tempo de tratamento na amostra do estudo.Descritores: Má oclusão; respiração bucal; tratamento ortodôntico. AbstractIntroduction: Several factors can interfere with orthodontic treatment, and it is important to verify which ones may hinder its success. Objective: To compare the duration of orthodontic treatment between nasal and mouth breathers with Angle Class II, Division 1 malocclusion. Material and method: This is an analytical observational study which used the records of orthodontic patients cared at a higher education institution in Sao Paulo state, Brazil, between 1999 and 2009. Data from the following variables were analyzed: age, gender, breathing mode (nasal or oral breathing), and treatment duration (beginning and end). Patients were matched for age and treatment used. The ANOVA test was applied to analyze the study data at 5% significance level (p<0.05). Result: The study sample consisted of 36 individuals, 16 female (10 nasal breathers and six mouth breathers) and 20 males (eight nasal breathers and 12 mouth breathers), aged nine to 15 years (mean age=13.021). As for orthodontic treatment duration, individuals in the nasal breathing group remained between 27 and 74 months (mean duration=39.61) under treatment, whereas treatment of individuals in the mouth breathing group lasted between 29 and 50 months (mean duration=36.66). No statistically significant differences were observed between the study groups. Conclusions: We conclude that the variable altered breathing mode does not interfere with treatment duration.

“…10 Although there is significant evidence that poor nasal breathing will lead to mouth-nasal breathing, its impact on dentofacial growth is still unclear. 33 Souki et al 34 observed that individual facial genotypes had different sensitivity on developing malocclusion; following the exposure to mouth breathing, a wide variety of interarch relationships could be found. It has been also shown that adenoidal/tonsillar hyperplasia or the presence of rhinitis have no association with the prevalence of Class II malocclusion, anterior open bite, and posterior crossbite in that sample of mouth breathers.…”

“…It has been also shown that adenoidal/tonsillar hyperplasia or the presence of rhinitis have no association with the prevalence of Class II malocclusion, anterior open bite, and posterior crossbite in that sample of mouth breathers. 34 In the study of Di Vece et al, 10 the relationship between CVA and TMD was investigated, and a significant correlation was reported. For visual analysis of the cervical vertebrae, morphologic anomalies known as vertebral defects were classified as round or concave by assessing the contact points of the edges of the vertebrae.…”

Objective: The literature indicates a correlation between vertebral morphologic anomalies and some orthodontic malocclusions. The aim of this study was to examine the occurrence of the types of cervical vertebral anomalies (CVAs) in subjects with transverse maxillary deficiency (TMD) and to compare this with the occurrence of CVA in a control group without TMD. Materials and Method: A sample of 47 Turkish patients (17 boys, 30 girls) with TMD and another sample of 47 Turkish patients (15 boys, 32 girls) with adequate maxillary transversal dimensions was studied. A visual assessment of the cervical column was made using lateral cephalometric films. Characteristics of the cervical column were classified according to Sandham as fusions and posterior arch deficiencies of C1 (PADs). Clinically normal appearance was determined when the first 4 vertebrae could be traced as separate entities with all anatomic components present. Differences in occurrence of CVA between the groups and between genders were assessed by v 2 independence test. Results: In the TMD group, 10,6% of the subjects had fusion in the cervical column, and 14,9% had PAD. In the control group, 17% of the subjects had fusion of the cervical column, and 8,5% had PAD. The occurrence of PAD was significantly increased in the TMD group (p,0.05), while no significant difference was found between the groups for occurrence of fusion (p.0.05). No statistically significant gender differences were found in the occurrence of CVA in the TMD group and the control group (p.0.05). Conclusion: No difference was found in the occurrence of fusion between the subjects with TMD and the subjects without TMD, and the occurrence of PAD was significantly increased in subjects with TMD.
