“…The definition of early treatment it a treatment which is started in the primary or mixed dentition to enhance the dental and skeletal development before the eruption of permanent dentition [41]. These early therapeutic methods are usually brief and simple, which elicits little cooperation from patients and their parents.…”

The aim of the present study was to obtain the prevalence of malocclusions in preschool children in Shanghai, China. A cross-sectional survey was conducted among 2335 children aged 3–5 years from kindergartens. Several occlusal parameters were clinically assessed, including second deciduous molar terminal plane, canine relationship, degree of overjet and overbite, anterior and posterior crossbite, and the presence or absence of physiologic spaces and crowding. All parents of subjects were asked to fill in the oral health knowledge questionnaires. The prevalence of malocclusion in primary dentition in Shanghai was 83.9%, and no significant differences were found in genders. Data showed that the prevalence of deep overbite (63.7%) was the highest in children with malocclusion, followed by deep overjet (33.9%), midline deviation (26.6%), anterior crossbite (8.0%) and anterior crowding (6.5%). The results revealed a high prevalence of malocclusion in primary dentition in children aged 3–5 years old of Shanghai, especially in vertical anomalies. The need for preventive orthodontic therapy is extremely desired and oral health education about malocclusion should be strengthened.

“…The incidence of malocclusion types may vary in different populations, and several studies (30)(31)(32)(33) have shown that the distribution of malocclusion is affected by the ethnic and cultural characteristics of the study sample (30). However, Class III malocclusion is usually the type that is encountered least frequently in sagittal projections (32,33). Epidemiological studies have found that patients with Class III malocclusion accounted for 10-12% in Turkish orthodontic patients (30), compared with 4.5% of 532 school children in India aged 7-13 yr (33).…”

The purpose of this study was to characterize the anatomy of the genial tubercle using cone beam computed tomography (CBCT). The morphology and detailed anatomy of the genial tubercle were assessed retrospectively in 201 patients (101 females, 100 males) using CBCT images. The parameters examined were the height (GH) and width (GW) of the genial tubercle, the distance from the lower incisors to the superior border of the tubercle (I-SGT), the distance from the inferior margin of the tubercle to the inferior margin of the mandible (IGM-IBM), and the anterior mandible thickness (AMT). Statistical analysis was performed to assess relationships among these parameters, gender, and orthodontic malocclusion (P < 0.05). The values obtained were GH 7.3-8.7 mm, GW 7.9-9.2 mm, I-SGT 7.1-9.1 mm, IGM-IBM 8.3-10.1 mm, and AMT 14.0-16.2 mm. GH, GW, and I-SGT showed no significant differences between genders (P > 0.05). However, IGM-IBM was larger for class III than for class I and class II male patients, and larger than for class I female patients. AMT in class III patients was greater than in class I and II patients (P < 0.05). The use of CBCT, which employs less radiation, is important for dental professionals,

“…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.…”

“…The specific scientific literature also reports interference in dental occlusion, and some of the studies on prevalence of malocclusions in oral breathers tend to show that Angle Class II malocclusion is greater than [7][8][9][10] Class I 11,12 .…”

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.
