Abstract Many viral infections cause oral manifestations, including disorders in odontogenesis, resulting in dental malformations. In this review, based on current knowledge, we will discuss the likely dental and oral consequences of COVID-19. In this article, we review currently available data associated with vertical transmission of COVID-19 and odontogenesis, oral manifestations, and the impact of COVID-19 pandemic on a diagnosis of oral diseases. Owing to the severity of the pandemic, the population's anxiety and fear of becoming infected with COVID-19 may underestimate the signs and symptoms of serious illnesses, besides discourage patients from seeking health, medical or dental services to determine the diagnosis of oral lesions. Thus, the COVID-19 pandemic could be an additional and aggravating factor for the delay of serious illness diagnosis, such as oral squamous cell carcinoma resulting in higher morbidity and worse prognosis. Several changes and oral lesions have been described as oral manifestations of COVID-19, such as dysgeusia, oral ulcers, petechiae, reddish macules, desquamative gingivitis, among others. Besides, it can cause major systemic changes and predispose opportunistic infections. As with other viral infections, oral manifestations, including dental anomalies, can occur as a direct result of SARS-CoV-2 infection. However, further studies are needed to guide and clarify possible oral changes.

O objetivo deste trabalho foi verificar os efeitos da aplicação de micronutrientes sobre a germinação e o vigor de sementes de mamona, especificamente a cultivar BRS 149 Nordestina. Utilizou-se o delineamento experimental inteiramente casualizado, com quatro repetições de 25 sementes. Os tratamentos constaram da testemunha, imersão em H2O, imersão em B, imersão em Zn, imersão em Cu, imersão em Mn, imersão em Mo e imersão em Fe. Por meio dos resultados obtidos, evidencia-se incremento na germinação e no vigor com a aplicação de micronutrientes às sementes de mamona. O B influenciou negativamente a germinação e o vigor e aumentou a porcentagem de sementes duras e dormentes.

The objective of this work was to evaluate the effect of micronutrient application on the germination and vigor of castor bean seeds, cv. BRS 149 Nordestina. A completely randomized design was used, with four repetitions of 25 seeds. The treatments were control, immersion in water, immersion in B, immersion in Zn, immersion in Cu, immersion in Mn, immersion in Mo and immersion in Fe. The results obtained indicate there was an increase in germination and vigor with the application of micronutrients in castor bean seeds. B was the most harmful on germination and vigor, and increased the percentage of impermeable and dormant seeds.
