RT causes changes that contribute to increased risk of tooth decay. Restorative treatments can be performed using adhesive procedures, but it is preferable to be performed before of the irradiation protocol, to guarantee better adhesive properties to restoration.

Post system had no significant effect on fracture resistance, regardless of the type of tooth. The mode of fracture was more restorable with glass fibre posts.

The characteristics of non-obese patients with mild to moderate Obstructive Sleep Apnea Syndrome (OSAS) who will present with a good response to Mandibular Repositioning Appliance (MRA) treatment have not yet been well established in the literature. The aim of this study is to assess whether polysomnographic (PSG), demographic, anthropometric, cephalometric, and otorhinolaryngological parameters predict MRA success in the treatment of OSAS. Forty (40) males with mild and moderate OSAS were assessed pretreatment and 2-months post-treatment after wearing an MRA. Demographic, anthropometric, otorhinolaryngological (ENT), cephalometric, and polysomnographic parameters, including continuous positive airway pressure (CPAP) titrated pressure, dental models, Epworth Sleepiness Scale, quality of life (Short Form SF-36), and mood state (Profile of Mood States -POMS), were assessed. The responders exhibited fewer oropharyngeal alterations, increased upper pharyngeal space, reduced lower airway space, and increased mandibular intercanine width, and they had milder disease. Nevertheless, no predictive factors of MRA success could be found. MRA was more successful among men with a more pervious airway, a larger interdental width and milder OSAS. However, a combined [1] functional and structural assessment is needed to successfully predict the [2] effectiveness of MRA treatment of OSA.

A pandemia por COVID-19 causou mudanças bruscas no cotidiano da população mundial, gerando necessidades adaptativas que nem sempre assimiladas de forma saudável por todos. Por esse motivo, os relatos de distúrbios, emocionais e físicos, são frequentes e com intensidades diferentes nos mais variados grupos. Entre as manifestações mais comuns estão as alterações no sono e o nível de estresse. Assim, os objetivos deste estudo foram avaliar o perfil de estresse e qualidade do sono de estudantes de odontologia após um mês de isolamento social e a influência dessas variáveis na rotina do estudo. Material e métodos: foi delineado um estudo observacional transversal aplicado usando o formulário Google. Os dados foram obtidos por meio de questionário sociodemográfico e instrumentos de avaliação do Índice de qualidade do sono de Pittsburgh, escala de sonolência de Epworth e escala de estresse percebido de Cohen. Resultados: Cerca de 62,5% dos 136 alunos avaliados apresentaram sono de má qualidade. Seus níveis de estresse eram elevados, com mediana de 32. A rotina de estudos estava comprometida em 62,5% dos alunos. Conclusão: O estresse induziu a baixa qualidade do sono e interferiu diretamente na rotina do estudo dos participantes, estabelecendo assim uma relação de causa e efeito.

Objective: To evaluate the maximum bite force (MBF) in subjects with and without Temporomandibular Dysfunction (TMD), in threedifferent positions (sitting, lying and standing). Methods: The sample consisted of 60 individuals, aged between 19 and 35 years,who were divided into two groups: with TMD (n = 30) and without TMD (n = 30). First, the RDC/TMD questionnaire was applied and,after diagnosis, all of the subjects selected were submitted to the measurement of MBF, on each side (right and left), in three differentpositions (sitting, lying and standing), by means of a digital gnatodynamometer. Results: No significant difference in mean MBF was foundbetween the two groups; however, the mean MBF for the subjects, comparing the same side and different positions, was significantlydifferent, being smaller when the individual was lying down. Conclusions: According to the results, it was concluded that the MBF isinfluenced by the change of position.

Introduction: Frequent episodic tension-type headache (FETTH), is described as frequent episodes of pain, located on both sides of the head, as a feeling of pressure or tightening, from mild to moderate intensity which may last from 30 minutes to seven days. The pain does not worsen with routine physical effort and may present photophobia or phonophobia. In this case, headache is one of the most common reasons for the complaint of children and adolescents, and it is a major problem among college students because it leads to the loss of study days and a decrease in academic performance. Objective: The aim of the present study was to conduct a survey on the prevalence of FETTH in students of Physiotherapy course of Centro Universitário do Triângulo (Unitri). Method: The research was done with the students registered in Physiotherapy course, in the second half of 2015, from the application of a questionnaire about the International Classification of Headache, according to the diagnostic criteria for FETTH. Result: Among the students, 18 (7.5%) presented FETTH, based on these classification criteria, but it was expected that 50% of the students expose symptoms indicative of TTHEF. Conclusion: It is concluded that FETTH is a type of headache that is not very prevalent in the academic context of the Physiotherapy course of the referred institution.
