Occurrence and patterns of orofacial injury in CrossFit practitioners.

BACKGROUND: CrossFit is an activity that can provide positive influences on body composition and physical fitness. However, the occurrence or pattern of possible injuries, especially in the orofacial region, has not yet been studied. The aim of this study was to investigate the occurrence and patterns of orofacial injuries in CrossFit practitioners. MATERIAL AND METHODS: This was a cross-sectional study carried out using an online questionnaire on the Google Forms platform. The volunteers were self-selected men and women who practice CrossFit and reside in Brazilian municipalities. The online survey was conducted during April 2020 and comprised 12 questions. The data were analyzed, categorized, and presented as percentages. RESULTS: These were 65 (27.8%) participants who reported having suffered at least one episode of orofacial trauma and they were more prevalent during training sessions 58 (89.2%). Among the regions with the highest frequency of injuries, the head 23 (21%), mental protuberance 22 (19.6%), upper lip 19 (16.9%), and maxillary teeth 14 (12.5%) were the most cited. CONCLUSIONS: The prevalence of injuries in the head region indicates a potential concern. Preference should be given to making mouthguards for the maxillary teeth, as they are significantly more affected by trauma during CrossFit when compared to the mandibular teeth.

PROPOSTA DE TERMO DE CONSENTIMENTO LIVRE E ESCLARECIDO PARA USO DE PROTETORES BUCAIS PERSONALIZADOS / Proposed of informed consent for use of personalized mouthguards

Durante a prática de esportes, especialmente considerando as modalidades de luta, a cavidade oral fica vulnerável aos eventos traumáticos decorrentes do contato entre os esportistas, o que pode comprometer o bom desenvolvimento da atividade e o próprio desempenho do atleta. A utilização de protetores bucais é uma medida fundamental para reduzir a ocorrência dessas injúrias e, principalmente as suas gravidades, favorecendo uma recuperação mais eficaz e rápida. Contudo, é obrigação ética do profissional e prerrogativa legal dos pacientes receber as informações relacionadas ao seu tratamento da forma mais completa possível, bem como certificar-se que os pacientes compreenderam estas questões. Neste trabalho, é apresentada uma proposta de um modelo de Termo de Consentimento Livre e Esclarecido para uso de protetores bucais personalizados, o qual aborda as questões pertinentes à confecção destes dispositivos. Este documento traz inúmeros benefícios para a especialidade, pois apresenta características como o fortalecimento do vínculo de confiança entre o dentista e o paciente atleta, a determinação de benefícios apropriados, riscos e encargos, a compreensão das vulnerabilidades entre as partes e a obtenção de permissões e aprovações. A confecção e o uso de protetores bucais apresentam especificidades importantes e estas devem estar esclarecidas para o paciente.

Periodontal Disease Impairs Muscle Recovery by Modulating the Recruitment of Leukocytes.

The purpose of this study is to analyze the impact of periodontal disease (PD) associated with physical exercise on inflammatory mediators and muscle repair. Twenty-four Wistar rats were divided into four groups: control (SH), healthy trained (TH), sedentary with PD (SP), and trained with PD (TP). PD was induced in groups SP and TP while the trained groups performed treadmill exercises for 8 weeks. For the analysis of IL-6, IL-10, TNF-α, and leukocyte count, we collected blood samples. Cryolesions were induced in the tibialis anterior and gastrocnemius, which were analyzed for morphological changes. The presence of PD modified leukocyte counts, while exercise showed an additive role. PD increased levels of IL-6, IL-10, and TNF-α, and physical exercise changed only values of IL-10. The association between physical exercise and PD was responsible for an increased concentration of leukocytes in the region of the inflammation. Serum levels of inflammatory markers were modified by PD and, when combined with exercise, may negatively modulate inflammation. The association between PD and physical exercise showed the most significant changes in the number of inflammatory cells and may negatively influence the process of muscle repair.

Oral manifestation of tuberculosis: a case-report.

The present case-report describes tuberculosis on the oral mucosa, in a rare manifestation of the disease. The importance of appropriate diagnosis and awareness of the clinical manifestations is highlighted. Oral lesions seem to occur as chronic ulcers, nodular or granular areas, and rare, firm leukoplakia regions. Most extra-pulmonary lesions represent secondary infections of a primary lung infectious focus; therefore, early and accurate diagnosis is required for planning of the best treatment and strategies to control the disease.
