Symptoms of post-COVID oral health conditions and their influence on the risk of developing dental pathology

Post-COVID syndrome is diagnosed if symptoms last longer than 3 weeks after the onset of the disease, and a chronic course of the disease is determined if symptoms persist for more than 12 weeks. The investigation considered patients’ complaints and the presence of infection in the oral cavity following COVID-19 and, based on this, evaluated the influence of distant symptoms on the risk of developing dental pathology. All subjects were interviewed using the most commonly used questionnaire OHIP-14, which determines the level of quality of life related to dental health. The most frequent complaint was a feeling of dryness in the oral cavity, which was reported by 30.04 % of the subjects (1.64 % in the control group). More than 24.90 % of patients who had COVID-19 noted loss of taste sensation (in the control group ‒ 1.64 %). Clinical oral examination of COVID-19 patients revealed such oral mucosal lesions as erythema, papules, vesicles, as well as periodontal and salivary gland disorders.
