The COVID-19 pandemic impacted the psychological wellbeing of populations worldwide. The purpose of the study. In this research, we assess changes on the dental status and the main indicators of life quality of dentist’s patients. Material and methods. Two groups of patients of three different ages were compared in the study. The 1st group was examined in 2015 and consisted of 175 patients, the 2nd group was examined in 2020. DMF index, hygienic index by J.C. Greene, J.R. Vermillion (ОНI-S, 1964), PMA index were determined. The data obtained were compared with each other. The questionnaire "Quality of life of psychosomatic patients" was applied. Three components: somatic, psychological and social were assessed. A score from 0 to 25 points corresponds to a low indicator, 44 to 86 points is an average one, 97 to 144 points is a high score. Results and discussion. At the first stage of the study, we assessed the dental status of patients before and after the pandemic. It should be noted that the morbidity structure has not changed significantly over the past 5 years. DMF index increased from 9.63±0.31 to 11.6±0.32 (p <0.05), the level of oral hygiene decreased - 2.55±0.16 versus 2.87±0.10 (p <0.05). We revealed an increase in the number of patients presented for dental care with high rates of caries intensity and decreased oral hygiene. A comparative analysis of the clinical indicators of patients showed that the COVID-19 epidemic, acting as a psychotraumatic factor, significantly reduced their quality of life in all respects. The overall assessment of life quality decreased by 18% in the observation period, P <0.05. The overall life quality value was characterized as high in 2015, but, unfortunately, this indicator corresponded to the average values. A similar trend was noted for all life quality components. The most significant decrease in life quality was noted for the somatic component, which decreased by 22% in 2020. The results of the study showed that the unfavorable epidemiological situation did not have a significant effect on young people, however, as for the elderly people, the pandemic reduced their satisfaction with life by 32%. People of middle age were the most resistant to the influence of the epidemiological situation. They had the average value of life quality indicators in 2020, but they did not differ significantly from the indicators of 2015. The psychological component of life quality evenly decreased in middle-aged and elderly people. This indicator of middle-aged people decreased by 20% and by 35% in older people. In the course of our study, it was found that the dynamics of a decrease in the social component of life quality directly depends on age. The changes are more noticeable with age. So, this indicator changed by 10%, for middle-aged people - by 17%, in the older age category - by 32%. Conclusion. The COVID-19 coronavirus pandemic has dramatically changed the lives of people around the world, including in Ukraine, negatively affecting life quality. Interventions to increase the economic security of the population will have far-reaching consequences in terms of improved mental health, and should be continued throughout the pandemic

Removable orthodontic appliances can be among the causes of microbial irritation in the oral cavity. The aim of the present study was to assess the oral hygiene status of patients with denture-related stomatitis. We carried out comprehensive dental checkup of 17 patients aged 51 to 69 years with denture-related stomatitis was performed. A bacterioscopic laboratory examination was performed for all patients. The denture hygiene index by E. Ambjörnsen has been determined. Denture-related stomatitis of the patients examined was manifested by various clinical signs. The species composition of the oral microflora when wearing removable dentures deviated from normal values. The Candida fungi were revealed in 13 (76.47%) cases; actinomycetes were recorded in 7 (42.2%) cases. We found that 82.35% of the patients with manifestations of denture-related stomatitis did not follow adequate oral hygienic. The study has shown that 3 (17.64%) cases were assessed as having satisfactory hygienic status. Poor denture hygiene (HI = 2.66) was observed in 5 (29.41%) of the cases. The unsatisfactory hygienic status of the dentures was recorded in 9 (52.94%) of cases and averaged 2.2. 15 (88.23%) patients were unaware of the importance of proper denture cleaning and did not use the hygiene algorithm in full. 3 (17.76%) patients did not did not remove dentures at nights, all the patients did not have a special double-sided brush. Only 5 (29.41%) of the respondents used dental elixirs fro mouth rinsing on regular basis. The results have demonstrated the importance of regular adequate care of dentures and strict adhering to an individual hygiene algorithm in full in order to prevent the occurrence of inflammatory processes in the oral cavity. The prevention is a key approach in the prophylaxis of side effects, which might be caused by dental appliances.

Despite of general tendency towards the decrease in the incidence of measles and rubella in recent years, there have been registered several outbreaks of these infections among young adults and adolescents at present. This case report describes a clinical case of measles suspected at the dental examination. The aim of this study is to make a clinical diagnosis of the patient and to draw attention of the dental professional and general physicians to the relevance of this problem. The prodromal phase of measles can be quite variable and mimic the clinical picture of other diseases, as it happened in our case, when the patient went to the dental office for symptoms of acute serous periodontitis. Belsky — Filatov — Koplik’s spots are reported to usually appear in 37.7-64.3% of cases (at the beginning of the measles rash period). In 57.5% of cases there is spot enanthema on the soft palate mucosa. Our patient presented only signs of acute catarrhal stomatitis. We would like to emphasize that 100% of patients with measles have catarrhal syndrome manifested with moderate signs of nasopharyngitis (nasal congestion, sore throat, dry cough), and only 42.8% suffer from conjunctivitis. This makes it difficult to diagnose this disease in its early period or to make differential diagnosis in the prodromal phase. An infected person can transmit the virus within 4 days before and after the rash appears that is very dangerous for surrounding people and for healthcare workers in particular. When making a diagnosis, it is important to remember that measles is a clinical diagnosis, and there is no opportunity to carry out an indicative rapid diagnosis (as with the flu), therefore every doctor should consider the issue of timely vaccination, and promotes preventive and educational work among the population.
