ABSTRACT
The prevalence of oral mucosal lesions in orthodontic patients with a history of COVID-19 has not been investigated before.
The aim of the study. To study the prevalence of oral mucosal lesions in orthodontic patients with a history of COVID-19.
Objects and methods.The work is based on a prospective and retrospective study of 74 patients undergoing orthodontic treatment. The examination of 74 orthodontic patients with the use of fixed orthodontic appliance (bracket system) at the Department of Pediatric Dentistry and Orthodontics advanced training and retraining of Vitebsk State Order of Peoples’ Friendship Medical University and the branch № 1 of Vitebsk Regional Clinical Dental Center during the period from January 2020 to September 2021 was carried out. In this study, the prevalence of traumatic lesions of oral mucosa of patients, salivation rate, Ph oral fluid and viscosity of oral fluid were determined.
Results and discussion. Patients with a history of COVID-19 are at higher risk of oral mucosal trauma, due to depressed salivary gland function. In patients with a history of coronavirus infection there was a predominance of combined traumatic and cheek mucosal lesions, which manifested as catarrhal inflammation (areas of hyperemia and edema), erosions and ulceration of the oral mucosa. The prevalence of associated lesions of the oral mucosa was significantly higher (p < 0.05) in patients with mild to moderately-severe
coronavirus infection.
Conclusion. The results of the study suggest a higher incidence of traumatic lesions of the oral mucosa in orthodontic patients with a history of COVID-19.
