Objectives To assess the correlation between malocclusion and a history of bullying. Materials and Methods A cross-sectional study of 494 adolescents aged 12 to 15 years was conducted. The National School Health Survey questionnaire (PeNSE 1 and 2) was used to determine history of bullying by identifying the victim and the abuser. Variables were evaluated based on the individual (age), environment (income, father's and mother's education, housing, government assistance, and parents' occupation), social and emotional well-being (CPQ11–14 domains), self-perceived need for orthodontic treatment, and clinical conditions (crowding, diastema, maxillary and mandibular overjet, and anterior open bite). Data were analyzed by Spearman correlation and by multivariate analysis, which allowed graphical representation of the eight variables studied in only two dimensions. Results There was no correlation between bullying and variables related to the individual and the environment. Maxillary overjet and self-perception related to the need for orthodontic treatment were important to explain the data variability. Conclusions Malocclusion did not correlate with bullying history. However, increased maxillary overjet influences adolescent self-perception, suggesting a potential condition for bullying events.

Purpose: to analyze the electromyographic activity of the suprahyoid muscles during deglutition in participants with Angle's Class II malocclusion. Methods: electromyographic data recordings were performed in the supra-hyoid muscles during swallowing and at rest, in 30 volunteers, 15 Angle's Class I participants and 15 Angle's Class II malocclusion, aged 15-27 years old. The Root Means Square values for both tests were analyzed, and for the deglutition test, the Linear Envelope was used to observe the type of muscle activation pattern. Results: during the test at rest, there was no significant difference in Root Means Square values (p=0.22) between Class I and Class II subjects. During deglutition, it was found that Angle's Class II subjects had significantly higher RMS values (p=0.01) as compared to Class I volunteers. Regarding the type of muscle activation pattern, there was a significant difference between Class I and Class II participants with a predominance of type 1 peak for Class I and type 2 peak for Class II. Conclusion: there was a difference in electromyographic recordings during deglutition in participants with Angle's Class II as compared to Class I participants with a tendency towards two contraction peaks, showing a greater imbalance during the function. There was no difference between groups in the rest position.

Os distúrbios osteomusculares relacionados ao trabalho (DORT) é o nome genérico dado a um conjunto de afecções heterogêneas que acometem músculos, articulações e nervos, que pode aparecer em indivíduos submetidos a certas condições de trabalho. Portanto, o presente estudo teve como objetivo verificar a prevalência dos sintomas de DORT em estudantes e professores do curso de odontologia. Para avaliação dos sintomas de DORT foi utilizado a versão brasileira do Questionário Nórdico de Sintomas Osteomusculares (QNSO), aplicado a uma amostra de indivíduos estudantes e professores do curso de odontologia. Para compreensão dos dados, foi realizado análises descritivas dos dados. Quinhentos e cinco (n=505) indivíduos participaram do estudo, sendo 75% do sexo feminino e 25% do sexo masculino. Do total de entrevistados 30% relataram uma jornada de trabalho de seis horas, 51% uma jornada de até oito horas e 19% uma jornada de trabalho superior a oito horas. Em relação à dor musculoesquelética, 76% da amostra relatou dor na região cervical e lombar com certa frequência. Os resultados preliminares do presente estudo sustentam a hipótese de que os sintomas de DORT podem se iniciar logo na graduação de estudantes de odontologia, com frequência nas regiões cervical e lombar.
