The prevalence and clinical relevance of viremia in patients with COVID-19 have not been well investigated. Seeking to understand the need for dentistry to perform bloody procedures in critically ill patients with COVID-19 admitted to the ICU, the quantification of the magnitude of viral replication may play a fundamental role in this scenario. For this, it is necessary to study the viremia kinetics of SARS-CoV-2, seeking to assess whether there is any characteristic pattern that may be associated with a worse clinical outcome of the patient with COVID-19 after undergoing bloody dental procedures, therefore, the objective of this research will be to investigate the occurrence of viral kinetics produced by dental procedures in patients with SARS-CoV-2 in Intensive Care Units, where, in addition to analyzing the oral health condition, the viral kinetics of SARS-CoV-2 will also be investigated by means of reverse transcription polymerase chain reaction (RT-PCR) examination of blood samples from patients with COVID-19 undergoing bloody dental treatment. This research is expected to identify risks and consequences regarding the possibility of performing bloody dental treatment in patients with COVID-19 in serious condition, in addition to verifying the association of the impact of oral infection foci on this profile of patients.
