- ItemAcesso aberto (Open Access)Relação entre determinantes socioeconômicos e hábitos bucais de risco para más-oclusões em pré-escolares(Sociedade Brasileira de Pesquisa Odontológica e Faculdade de Odontologia da Universidade de São Paulo, 2000-06-01) Tomita, Nilce Emy; Sheiham, Aubrey; Bijella, Vitoriano Truvijo; Franco, Laercio Joel [UNIFESP]; Universidade de São Paulo (USP); University College London Medical School Department of Epidemiology and Public Health; Universidade Federal de São Paulo (UNIFESP)In order to evaluate how socioeconomic determinants affect the prevalence of oral habits in preschool children, this cross-sectional study was developed. The survey was carried out from October, 1994 to December, 1995. A random sample of 2,139 children aged 3 to 5 years old was evaluated. The children were enrolled in private or public institutions in the Municipal District of Bauru, São Paulo, Brazil. A sub-sample of 618 children presented response to the socioeconomic questionnaire. The considered hypothesis is that socioeconomic determinants affect the psychological status of the child, and it is observed through the development of deleterious oral habits, like dummy-sucking or digit-sucking. The results were tested by bivariate analysis (chi-square test). Some social determinants, like the mother s employment and the occupation of the person who has the greater income in the household, are related to oral habits (p < 0.05), which in turn are strongly associated with malocclusion.
- ItemAcesso aberto (Open Access)Relação entre diâmetro bizigomático e bigoníaco em indivíduos saudáveis(Universidade Federal de São Paulo, 2021-12-03) Wu, Giovane [UNIFESP]; Bommarito, Silvana [UNIFESP]; http://lattes.cnpq.br/5606969949793059; http://lattes.cnpq.br/7232352793039160Objetivo: O objetivo desse estudo foi analisar a relação entre os diâmetros bigoníaco e bizigomático de indivíduos saudáveis. Método: participaram 126 indivíduos adultos saudáveis na faixa etária entre 18 e 39 anos. Foram realizadas anamnese, avaliação prosopométrica constituída por medição dos diâmetros bigoníaco e bizigomático com paquímetro ósseo CESCORF e avaliação da oclusão dentária, segundo Angle (1899). Resultados: Ao compararmos os diâmetros bizigomático e bigoníaco foi observado que os homens possuem ambas medidas maiores que as mulheres. Não houve variação significativa comparando o diâmetro bizigomático em pacientes com oclusão normal ou Classe I e, pacientes com maloclusão Classe I apresentaram diâmetro bigoníaco maior que pacientes com oclusão normal. Conclusão: O sexo masculino apresentou maior diâmetro bizigomático e bigoníaco comparado ao sexo feminino. As maloclusões apresentaram menor diâmetro bigoníaco comparado a oclusão normal.
- ItemAcesso aberto (Open Access)Relação entre força máxima de mordida e ângulo goníaco na mordida cruzada(Universidade Federal de São Paulo (UNIFESP), 2017-02-24) Said, Angelica Da Veiga [UNIFESP]; Monteiro, Silvana Bommarito [UNIFESP]; http://lattes.cnpq.br/5606969949793059; http://lattes.cnpq.br/4999433899060641; Universidade Federal de São Paulo (UNIFESP)Objective: To analyze the maximum bite force in unilateral posterior cross-bite and the correlation between maximum bite force and gonial angle in adults. Method: A total of 160 individuals, 88 males and 72 females, aged between 18 and 39 years old, were divided into two groups: without cross-bite, composed of 130 individuals (75 males and 55 females) and with cross-bite, consisting of 30 individuals (13 males and 17 females). The method consisted of the steps of anamnesis, evaluation of the occlusion, recording of the maximum bite force and registration of the gonial angle. The occlusion evaluation was performed to classify the occlusion in without or with cross-bite. The maximum bite force was recorded with a DDK / M model digital dynamometer (Kratos, São Paulo, Brazil) and in all subjects, three measurements were performed with the device positioned on the occlusal surface of the first molars, alternately, and with one minute interval between each series, and the averages are then calculated. The registration of the gonial angle was obtained with a goniometer measuring the right and left sides. The data collected were statistically analyzed by ANOVA, paired T-Student and Pearson's correlation, considering a significance level of 0.05 (5%). Results: There was greater maximum bite force in males, independently of the group and side; in the without cross-bite group there was difference of the maximum bite force between sides only in females; between groups, there was greater maximum bite force in males in the without cross-bite group. The correlations found between maximum bite force and gonial angle in both groups were negative or inversely proportional. Conclusions: The cross-bite group had a lower maximum bite force in males and the correlation between maximum bite force and gonial angle was negative, indicating that greater the maximum bite force, lower the gonial angle or vice versa. The direct measurement was shown as a good clinical option for recording the gonial angle.
- ItemAcesso aberto (Open Access)Relação entre hábitos bucais e má oclusão em pré-escolares(Faculdade de Saúde Pública da Universidade de São Paulo, 2000-06-01) Tomita, Nilce Emy; Bijella, Vitoriano Truvijo; Franco, Laercio Joel [UNIFESP]; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: To evaluate the way oral habits and speech problems affect dental occlusion in preschool children. METHODS: A random sample of 2,139 boys and girls aged 3-5 years old was evaluated. The children were enrolled in private and state institutions in the city of Bauru, São Paulo State, Brazil. The cross-sectional study was developed in two steps: occlusion assessment, and a questionnaire about their social and economic status. The occlusal anatomical-functional characteristics assessment was done according to Angle classification. Additionally, overjet, overbite, crowding, anterior open bite, posterior crossbite, and anterior crossbite were evaluated. A sub-sample of 618 children filled out the questionnaire. The prevalence of malocclusion and some variables of exposure were tested by bivariate analysis. RESULTS: The prevalence of malocclusion was 51.3% for boys and 56.9% for girls. There was no difference related to gender. In regard to age, there was a higher prevalence of malocclusion in the 3 year-old group, which decreased significantly with age (p<0.05). CONCLUSIONS: Among the environmental factors evaluated, the habit of sucking a pacifier was the most important in the association with malocclusion (OR=5.46) followed by the habit of sucking fingers (OR=1.54). Speech problems did not show any influence in malocclusion occurrence.
