This study evaluated the relationship among malocclusion, number of occlusal pairs, masticatory performance, masticatory time and masticatory ability in completely dentate subjects. Eighty healthy subjects (mean age = 19.40 ± 4.14 years) were grouped according to malocclusion diagnosis (n = 16): Class I, Class Class II-2, Class III and Normocclusion (control). Number of occlusal pairs was determined clinically. Masticatory performance was evaluated by the sieving method, and the time used for the comminute test food was registered as the masticatory time. Masticatory ability was measured by a dichotomic self-perception questionnaire. Statistical analysis was done by one-way ANOVA, ANOVA on ranks, Chi-Square and Spearman tests. Class II-1 and III malocclusion groups presented a smaller number of occlusal pairs than Normocclusion (p < 0.0001), Class I (p < 0.001) and II-2 (p < 0.0001) malocclusion groups. Class I, and III malocclusion groups showed lower masticatory performance values compared to Normocclusion (p < 0.05) and Class II-2 (p < 0.05) malocclusion groups. There were no differences in masticatory time (p = 0.156) and ability (χ2 = 3.58/p= 0.465) among groups. Occlusal pairs were associated with malocclusion (rho = 0.444/p < 0.0001) and masticatory performance (rho = 0.393/p < 0.0001)...

OBJECTIVE: Define and compare numbers and types of occlusal contacts in maximum intercuspation. METHODS: The study consisted of clinical and photographic analysis of occlusal contacts in maximum intercuspation. Twenty-six Caucasian Brazilian subjects were selected before orthodontic treatment, 20 males and 6 females, with ages ranging between 12 and 18 years. The subjects were diagnosed and grouped as follows: 13 with Angle Class I malocclusion and 13 with Angle Class II Division 1 malocclusion. After analysis, the occlusal contacts were classified according to the established criteria as: tripodism, bipodism, monopodism (respectively, three, two or one contact point with the slope of the fossa); cuspid to a marginal ridge; cuspid to two marginal ridges; cuspid tip to opposite inclined plane; surface to surface; and edge to edge. RESULTS: The mean number of occlusal contacts per subject in Class I malocclusion was 43.38 and for Class II Division 1 malocclusion it was 44.38, this difference was not statistically significant (p>0.05). CONCLUSIONS: There is a variety of factors that influence the number of occlusal contacts between a Class I and a Class II, Division 1 malocclusion. There is no standardization of occlusal contact type according to the studied malocclusions. A proper selection of occlusal contact types such as cuspid to fossa or cuspid to marginal ridge and its location in the teeth should be individually defined according to the demands of each case. The existence of an adequate occlusal contact leads to a correct distribution of forces...

As fissuras labiopalatinas acarretam uma série de implicações funcionais, estéticas e psicossociais. Algumas destas alterações são inerentes à esta malformação, como por exemplo, a maloclusão que pode ocorrer em conseqüência de uma série de fatores, entre eles, a tensão da musculatura bucal, a descontinuidade do arco pela sua segmentação, a erupção dentária ectópica, a tensão cicatricial proveniente das cirurgias primárias e a verticalização dos incisivos superiores. Por estas razões nos propusemos, neste estudo, a diagnosticar o tipo e a freqüência das maloclusões em portadores de fissura labiopalatina, na faixa etária de 3 a 6 anos, relacionando os dados encontrados com a extensão da fenda e comparando-os com o tipo e freqüência das maloclusões no Grupo Controle. Os resultados encontrados nos levam a afirmar que não houve significância estatística nos tipos de maloclusão em relação à extensão da fissura, contudo, encontramos diferença significante quando comparado o tipo e freqüência das maloclusões no Grupo Controle.; The cleft lip and palate leads to a range of functional, esthetics and psychosocial implications. Some of those changes are inherent to this malformation, such as the malocclusion that might occur due to a variety of factors...

O objetivo desse estudo foi avaliar a relação entre o grau de severidade da má oclusão de Classe II e o sucesso do tratamento sem extração desses pacientes. A amostra se constituiu de 277 pacientes que apresentavam inicialmente má oclusão de Classe II, de ambos os sexos, nas fases de dentadura mista tardia ou permanente que foram tratados ortodonticamente sem extração. Os pacientes foram divididos em 2 grupos. O grupo 1 constituído por pacientes que apresentavam má oclusão de ½ Classe II. O grupo 2 constituído por pacientes que apresentavam má oclusão de Classe II completa. Estes pacientes foram selecionados em caráter retrospectivo, verificando-se todo o arquivo da Disciplina de Ortodontia da Faculdade de Odontologia de Bauru - USP. O Índice de Prioridade de Tratamento (IPT) foi utilizado para verificar a severidade inicial da má oclusão assim como os resultados oclusais ao final do tratamento de cada paciente. As médias dos escores iniciais e finais do IPT foram comparadas entre os grupos pelo teste t não pareado. O índice de eficiência foi calculado pela proporção entre a porcentagem de melhora pelo tempo de duração do tratamento. Os resultados mostraram uma diferença significante entre os grupos. Houve maior proporção de sucesso do tratamento ortodôntico sem extrações da má oclusão de ½ Classe II em comparação à Classe II completa. O tempo do tratamento ortodôntico foi maior nos pacientes que apresentavam inicialmente ao tratamento...

A má oclusão e o bruxismo são problemas que podem interferir na qualidade de vida de adolescentes. Este estudo observacional transversal e analítico teve como objetivo investigar a associação entre má oclusão e bruxismo, com a qualidade de vida de adolescentes entre 12-15 anos de idade. A amostra foi selecionada por conglomerado e composta por 370 adolescentes de ambos os gêneros, estudantes da rede estadual de ensino de Bauru-SP. A má oclusão foi medida pelo Dental Aesthetics Index (DAI). Para o bruxismo foram avaliadas as facetas de desgastes dos dentes por meio do Índice de Desgaste Dentário (IDD). Foram aplicados dois questionários, um para o bruxismo e o outro para a qualidade de vida (OHIP-14). O Índice de Massa Corporal (IMC) foi calculado segundo normas da OMS. Teste Qui-quadrado, Correlação de Spearman, Mann-Whitney e Kruskall-Wallis foram aplicados (P<0,05). A má oclusão muito severa e o bruxismo foram mais prevalentes no gênero feminino, enquanto no masculino identificou-se a má oclusão definida. O bruxismo autorrelatado foi encontrado em 18,9% dos adolescentes. A maioria dos adolescentes apresentou peso normal. Bruxismo, apinhamento, mordida aberta, relação molar e desalinhamento maxilar estiveram relacionados à qualidade de vida (p<0...

Essa tese foi dividida em dois capítulos. Capítulo 1: O desenvolvimento da maloclusão é o resultado de interações entre fatores genéticos e ambientais, e a função orofacial é considerada um fator ambiental. Dessa forma, o presente estudo objetivou determinar a prevalência de disfunção orofacial e maloclusão, e estabelecer a interrelação entre disfunção orofacial e maloclusão em crianças e adolescentes de 4 a 14 anos de idade. A amostra consistiu de 1561 sujeitos divididos em quatro grupos: Dentição decídua (DD), Dentição mista 1º período transitório (DM1), Dentição mista 2º período transitório (DM2) e Dentição permanente (DP). A disfunção orofacial foi avaliada usando o Nordic Orofacial Test ¿ Screening (NOT-S) e a maloclusão foi avaliada utilizando critérios sugeridos por Grabowski et al. 2007, e, a partir disso a amostra foi subdividida em grupos sem maloclusão e com os tipos de maloclusão. A análise estatística consistiu de análise descritiva dos dados, e aplicação dos testes Qui-quadrado, Mann-Whitney e Kruskal-Wallis. A prevalência da maloclusão encontrada foi de 64.9% na DD, 83.2% na DM1, 80.4% na DM2 e 90.7% na DP, sendo a sobressaliência aumentada a maloclusão mais frequente. A frequência de disfunção orofacial encontrada foi de 86.6% na DD...

The purpose of the present study was to evaluate the impact of malocclusion on Oral Health-Related Quality of Life (OHRQoL) of children and their families. A population-based cross-sectional study was carried out in Belo Horizonte, MG, Brazil. A representative sample of 1069 male and female preschoolers aged 60 to 71 months was randomly selected from public and private preschools and daycare centers. Data were collected using the B-ECOHIS. In addition, a questionnaire addressing socioeconomic and demographic data was self-administered by the parents/guardians. The criteria used to diagnose malocclusion were based on Foster and Hamilton (1969), Graboswki et al. (2007) and Oliveira et al. (2008). Descriptive, univariate and multiple Poison logistic regression analyses were carried out. The prevalence of malocclusion was observed in 46.2% of the children and deep overbite was the most prevalent type of malocclusion (19.7%), followed by posterior crossbite (13.1%), accentuated overjet (10.5%), anterior open bite (7.9%) and anterior crossbite (6.7%). The impact of malocclusion on OHRQoL was 32.7% among the children and 27.1% among the families. In Poisson multiple regression model adjusted for socioeconomic status, no significant association was found between malocclusion and OHRQoL of the children (PR=1.09...

This study aims to critically review the literature in respect to craniofacial bone abnormalities and malocclusion in sickle cell anemia individuals. The Bireme and Pubmed electronic databases were searched using the following keywords: malocclusion, maxillofacial abnormalities, and Angle Class I, Class II and lass III malocclusions combined with sickle cell anemia. The search was limited to publications in English, Spanish or Portuguese with review articles and clinical cases being excluded from this study. Ten scientific publications were identified, of which three were not included as they were review articles. There was a consistent observation of orthodontic and orthopedic variations associated with sickle cell anemia, especially maxillary protrusions. However, convenience sampling, sometimes without any control group, and the lack of estimates of association and hypotheses testing undermined the possibility of causal inferences. It was concluded that despite the high frequency of craniofacial bone abnormalities and malocclusion among patients with sickle cell anemia, there is insufficient scientific proof that this disease causes malocclusion

The aims of the present study were to compare aspects related to malocclusion between individuals with Down syndrome (DS) and a control group, establish malocclusion severity, and identify determinant factors. A total of 120 individuals (60 with DS and 60 with no physical or mental impairment), were included in the study. Data were collected through interviews, analyses of the medical charts, and oral examinations. The criteria of the Dental Aesthetic Index were used for the diagnosis of malocclusion. Chi-square test (p ≤ 0.05) and multivariate logistic regression were used for comparisons between the two groups and to determine the association between the dependent (malocclusion severity) and independent variables. Statistically significant differences were found between the two groups for the following variables: missing teeth, diastema, overjet, mandibular protrusion, anterior open bite, posterior crossbite, facial type, lip incompetence, and Angle classification. DS, a history of premature birth, and long face pattern were found to be associated with malocclusion severity. Individuals with DS exhibited more occlusal problems than those in the control group.

INTRODUCTION: Oral habits may interfere on the growth and development of the stomatognathic system and orofacial myofunctional conditions, producing changes in the position of teeth in their dental arches. OBJECTIVE: The purpose of this study was to verify the presence of deleterious oral habits in individuals with malocclusion and see if there is a predominance of Class II malocclusion in these individuals. METHODS: The records of 140 patients treated at the Clinic of Preventive Orthodontics FORP-USP who had already completed treatment were randomly selected and analyzed. Their ages ranged from 6 to 10 years and 11 months. Associations were made between the presence or absence of deleterious oral habits, type and number of habits found in each individual and the type of malocclusion according to Angle classification. The statistical analysis used was the Chi-square test with a significance level of 5%. History of deleterious oral habits was found in 67.1% of individuals. RESULTS: The Class I malocclusion was most frequent (82.9%), followed by Class II malocclusion (12.1%) and Class III (5%). CONCLUSION: There was a predominance of Class II malocclusion in individuals with a history of deleterious oral habits.

INTRODUCTION: The aim of this retrospective study was to compare the occlusal outcomes, duration and efficiency of Class I malocclusion treatment carried out with and without premolar extractions in patients with different degrees of initial malocclusion severity. METHODS: Complete records of 111 patients were obtained and divided into two groups: Group 1 consisted of 65 patients at an initial mean age of 13.82 years old treated with four premolar extractions; whereas Group 2 consisted of 46 patients at an initial mean age of 14.01 years old treated without extractions. Two subgroups were obtained from each group (1A, 1B, 2A and 2B) with different degrees of malocclusion severity according to the initial values of PAR index. Compatibility was assessed using chi-square and t-tests. The subgroups were compared by means of Analysis of Variance (ANOVA).The variables that might be related to treatment duration and efficiency were assessed using the multiple linear regression analysis. RESULTS: Initial malocclusion severity was positively related to the amount of occlusal correction and consequently to a higher efficiency index. Moreover, extraction protocol showed a positive relationship with treatment duration and a negative relationship with treatment efficiency. CONCLUSION: Extraction and non-extraction protocols for correction of Class I malocclusion provide similar satisfactory results; however...

Information on social inequities in health is valuable when allocating resources for public services and formulating health strategies. Research is needed to deepen the understanding of the determinants that lead to inequities in oral health. This cross-sectional study aimed to analyze the association between individual and contextual factors and the prevalence of adverse periodontal condition, malocclusion and dental fluorosis among Brazilian 12- year-old schoolchildren. This study included data from an oral health survey carried out in 2010 in the city of Goiania, Brazil (n = 2,075) and secondary data obtained from the files of the local health authority. Data were collected through oral clinical examinations. For assessment of periodontal status two components of the Community Periodontal Index (CPI) were used: calculus and bleeding after probing. The Dental Aesthetic Index (DAI) was used to assess occlusion and the Dean Index to assess fluorosis. Dependent variables were presence of any periodontal condition, presence of malocclusion (DAI>25) and presence of fluorosis, analyzed separately. Independent individual variables were the children’s sex and color/race, and their mother’s level of schooling. Contextual variables were related to the schools (type and existence of toothbrushing program) and its geographic location in the health districts. Rao-Scott tests were performed for each of the three outcomes and multilevel analysis was performed for periodontal condition (Poisson regression) and malocclusion (Logistic regression). The results are presented in three original articles. The prevalence of calculus and/or bleeding was 7% and higher (P<0.05) in brown pupils...

Malocclusions are highly prevalent in children and adolescents may cause impacts in their daily life as well as be expensive due to the treatments, therefore being considered as a public health problem. Thus, the purposes of this study are: to carry out a literature review addressing the main orthodontic treatment need indexes to be used in epidemiological studies in the mixed dentition stage and, perform a survey, in 8-12-years-old schoolchildren in Pelotas/RS, to check the prevalence of malocclusion and the orthodontic treatment need relating them to demographics and socioeconomics factors, as well as estimate the impact of malocclusion in oral health related to quality of life (OHRQoL). For this cross-sectional study, a minimum stratified random sample of 922 children was estimated for 20 schools (municipal, state and private). The data collection was composed of: questionnaire sent to the parents obtain socioeconomics variables; interview with the children to collect, among other information, demographic data and to apply the Child Perceptions Questionnaire (CPQ); oral clinical examination of the children for malocclusion, orthodontic treatment need (Dental Aesthetic Index - DAI), for dental caries (CPOD index) and for dental traumas (O Brien s index). For data analysis...

INTRODUCTION: Estimating orthodontic treatment need in the permanent dentition using information from the deciduous-dentition malocclusion may assist in defining the time for appropriate orthodontic intervention. Our objective was to investigate whether malocclusion in the deciduous teeth predicts orthodontic treatment need in the permanent dentition. METHODS: Two oral health studies nested in a birth cohort were carried out at ages 6 (n = 359) and 12 (n = 339) years. Open bite, crossbite, and canine malocclusion were assessed in the deciduous teeth. Orthodontic treatment need was determined in the permanent dentition using the dental esthetic index. Prevalence ratios were estimated using 2 dental esthetic index cutoff points: highly desirable/mandatory orthodontic treatment and only mandatory orthodontic treatment. We tested all combinations of the deciduous malocclusion and the outcomes, controlling for confounders. RESULTS: Children with only open bite and those with concurrent open bite and canine malocclusion were more likely to have either highly desirable/mandatory orthodontic treatment or only mandatory orthodontic treatment needs by age 12. The combination of crossbite and open bite in the deciduous teeth was associated with the highest risk of need for mandatory orthodontic treatment. CONCLUSIONS: Malocclusion in the deciduous teeth is a risk factor for orthodontic treatment need in the permanent dentition. Children with malocclusion at a young age should be monitored regularly...

OBJECTIVES: To test whether malocclusion had an impact on adolescents’ appearance satisfaction regardless of other physical aspects. METHODS: A cross-sectional study nested in a birth cohort study was carried out in Pelotas, Brazil. A random sample of 900 15-year-old adolescents was selected. WHO criteria were used to define malocclusion and a questionnaire was administered including self-reported skin colour and appearance satisfaction. Dental caries were assessed. Height and weight were measured and body mass index calculated. Data concerning gender and socioeconomic characteristics were obtained from the cohort’s perinatal study. Adjusted analyses including all confounding variables investigated were performed using Poisson regression with robust variance in order to identify the potential risk factors for appearance dissatisfaction. All analyses were carried out separately by gender. RESULTS: The sample included 867 individuals, 54.1% men. The prevalence of moderate or severe malocclusion was 30.6% (95% CI: 26.5–34.7) among boys, and 32.8% (95% CI: 28.2–37.4) among girls (P ¼ 0.524). Dissatisfaction with appearance was reported by 29.8% of the boys and by 46.5% of the girls (P < 0.001). A positive association between malocclusion and appearance dissatisfaction...

Skeletal Class III malocclusion, with its unpredictable and unfavorable nature, has been characterized by a growth pattern with doubtful prognosis regarding orthodontic mechanics, even when performed early. For a long time, Class III malocclusion was regarded as a synonym of mandibular prognathism, regardless of the affected skeletal structures. Mandibular growth, essentially determined by genetic factors, could barely be controlled by early orthodontic interventions. Therefore, the treatment choice was to wait for the patient to grow, and then make an orthodontic intervention associated with an orthognathic surgery. Maxillary involvement in the etiology of Class III malocclusion was conclusive to change orthodontic therapeutics. Maxillary intramembranous growth has a better response to orthopedic treatment, based on growth control and redirection, thus contributing for early intervention success. In several cases, excellent results have been achieved with rapid maxillary expansion and protraction. The aim of this study was to describe and discuss the treatment of a patient with Class III malocclusion, whose treatment planning comprised two phases: interceptive (mechanical orthopedic appliances) and comprehensive (fixed orthodontic appliance). The results of this case showed that Class III malocclusion should be intercepted as early as possible to permit growth redirection...

The aim of the present study was to determine the prevalence of malocclusion and associations with socioeconomic indicators among preschoolers. A cross-sectional study was conducted with 732 children 3 to 5 years of age in the city of Campina Grande, Brazil. Three dentists underwent a calibration exercise (K = 0.85-0.90) and diagnosed malocclusion based on the criteria proposed by Foster & Hamilton and Grabowski et al. Parents/guardians answered a questionnaire addressing sociodemographic aspects. Data analysis involved descriptive statistics and bivariate Poisson regression (PR; α = 5%). The prevalence of malocclusion was 62.4%. The most frequent types were increased overjet (42.6%), anterior open bite (21%) and deep overbite (19.3%). An association was found between malocclusion and age: the prevalence of malocclusion was greater among younger children, with the highest prevalence among 3-year-olds (PR = 1.116; 95%CI = 1.049-1.187). The prevalence of malocclusion was high. Mother's schooling and household income were not associated with malocclusion. Socioeconomic factors were also not associated with the occurrence of malocclusion.
