Some oral manifestations have been observed in patients with coronavirus disease 2019 . However, there is still a question about whether these lesions are due to coronavirus infection or secondary manifestations resulting from the patient's systemic condition. Thus, this article aims to report an additional case of an oral condition in a patient diagnosed with COVID-19. Our patient, a sixty-sevenyear-old Caucasian man, tested positive to coronavirus and presented oral manifestations such as recurrent herpes simplex, candidiasis, and geographic tongue. We support the argument that some oral conditions could be secondary to the deterioration of systemic health or due to treatments for COVID-19. The present case report highlights the importance of including dentists in the intensive care unit multiprofessional team to improve oral health in critical patients, not only COVID-19 patients, but also, to contribute to evidence-based and decision-making in managing infectious diseases.

Background/Aims Traumatic dental injuries (TDI) are most prevalent during adolescence and infancy, and they have an important impact on the oral health‐related quality of life (OHRQoL). The aim of this study was to assess the effect of dental treatment and the severity of TDI on the OHRQoL of schoolchildren in public schools in Brazil. Materials and Methods This cross‐sectional study evaluated schoolchildren aged 11 to 14 years in Brasilia, Brazil. The criteria used for the examinations were TDI—O’Brien criteria; Dental caries—DMFT criteria; and malocclusion—the Dental Aesthetic Index. The impact of oral health on the children's quality of life was assessed with the Child Perceptions Questionnaire (CPQ11–14) that was completed by the children while on the school premises. Socio‐demographic information was also collected from the parents. Statistical analysis was performed using non‐parametric and association tests, as well as linear regression. Results A total of 20.2% of the students had some TDI in their permanent anterior teeth; 20% of traumatized teeth were treated, and 80% were not treated. Sorting by severity, 75.1% of the schoolchildren had a TDI involving only the enamel, and 24.9% had a TDI extending beyond the enamel. Significant differences were observed between the severity of a TDI and the total scores of CPQ11–14 (Kruskal–Wallis; p = 0.0026), emotional well‐being (p = 0.0006), and social well‐being (p = 0.0001) when the group with TDI extending beyond the enamel was compared with the other groups (control and with TDI involving only the enamel), even after adjustment for socio‐demographic and clinical variables. For oral symptoms and functional limitation, no differences were observed among the groups. Conclusions Dental trauma and fractures extending beyond the enamel, treated or not, have a negative impact on the OHRQoL of schoolchildren, suggesting effects on self‐perception and in the social and emotional spheres.
