In 2019 a highly contagious virus responsible for the current pandemic, called SARS-CoV-2, emerged in China. Among the main symptoms are fatigue, fever, dry cough, and respiratory failure. However, some symptoms have stood out and attracted researchers: anosmia and dysgeusia. Sensory function is related to motor function. Thus, the evaluation of the sensory-motor-oral system in a broader way becomes indispensable, allowing a better understanding of these alterations in this public.

The purpose of this study was to preliminarily analyze, by means of standardized clinical protocols, the orofacial myofunctional function aspects of adult individuals affected by SARS-CoV-2 after clinical recovery, from a comparative study with a control group, and to relate the literature findings to the aspects identified.

This is a descriptive observational study. Individuals recovered from COVID-19 will be recruited to the study to compose the research group. Those who did not have the disease will be included in the control group, considering the inclusion and exclusion criteria for both groups. Specific tests were selected, according to feasibility, to evaluate the functions of smell, taste, oral stereognosis and swallowing, which will be applied during an individual session, according to the manufacturer's/tenderer's instructions, by previously trained evaluators.

As for the orofacial myofunctional system and swallowing, the GP (research group) showed better performance in the evaluation, although with a low difference in the results. Although the CG (control group) and GP had adequate answers higher than 50% in the oral stereognosy test, when compared, the GP showed better performance. There is an alteration of the olfactory system when the groups are compared, with greater impairment in the GP.

It was possible to confirm the existence of orofacial myofunctional manifestations in individuals recovered from COVID-19. It was possible to have an integral and direct evaluation of the patient, which will allow the maintenance of care after the cure of the underlying disease.

It is difficult to find collections on taste disorders, oral stereognosia, and swallowing in post-COVID-19 patients, highlighting the importance of this study. Moreover, there is no research on these disorders, specifically for the public from the Federal District. Most studies are focused on patient survival; thus, this research aims to investigate the sequelae the disease to enable a holistic view for the maintenance of care.
