[Key dental challenges during COVID-19 pandemic: oral health monitoring in patients with chronic oral mucosal diseases]. / Klyuchevye stomatologicheskie problemy perioda pandemii COVID-19: monitoring sostoyaniya stomatologicheskogo zdorov'ya u patsientov s khronicheskimi zabolevaniyami slizistoi obolochki polosti rta.

OBJECTIVE: To develop an effective system of an interactive dynamic telemonitoring of oral health in patients with oral lichen planus (LP) during the COVID-19 pandemic. MATERIAL AND METHODS: The observational longitudinal prospective cohort study (follow-up for 12 months) involved 53 patients (19 men and 34 women aged 49-65 years) with various forms of LP in persistent remission. During the entire observation period dentists carried out telemonitoring (through a Telegram group) of oral health of patients with LP registering the preservation/coming out from remission, as well as the causes of exacerbation of LP. RESULTS: The developed interactive monitoring system based on the use of available video feedback communication technologies (via Telegram, WhatsApp, Viber messengers) provided stable remission in 28.3% of patients with LP (mainly typical and hyperkeratotic forms) and effective relief of exacerbations (mainly erosive-ulcerative forms) associated with the new coronavirus infection COVID-19 in 35.8% of cases, exacerbation of concomitant systemic pathology (excluding COVID-19) in 16.9%, local traumatic risk factors in 15.1%, development of post-vaccination reactions in 3.9%. COVID-19-associated exacerbation of LP is a polymorphic symptom complex manifested by a change in classical clinical picture and heavier course of skin-mucosal dermatosis due to the addition of new, atypical for LP, manifested COVID-19-associated intraoral symptoms and generalization of skin lesions. Periods of exacerbation of LP in COVID-19 patients are significantly longer, with shorter remissions than in the prepandemic period. CONCLUSION: Interactive telemonitoring of oral health in patients with chronic oral mucosal diseases is a safe and effective tool for dispensary observation, management and maintenance of social communications during periods of social isolation.

[Mucoperiodontal lesions: improvement of prosthodontic treatment considering initial indicators of patients' oral health]. / Mukoparodontal'nye porazheniya: sovershenstvovanie ortopedicheskogo stomatologicheskogo lecheniya s uchetom iskhodnykh pokazatelei zdorov'ya polosti rta patsientov.

OBJECTIVE: To assess the need for prosthodontic treatment and to substantiate the features and perspectives for optimizing prosthodontic treatment in patients with mucoperiodontal manifestations of lichen planus (LP). MATERIAL AND METHODS: For assessment of the need and identification of problematic aspects of prosthetic treatment 74 patients (48.3% of the primary sample of all patients with oral LP) with oral LP-associated mucoperiodontal lesions (MPL) participated in a multicenter open cohort prospective controlled clinical trial with elements of retrospective analysis. The prospective part of the study summarizes the results of prosthodontic treatment of 41 patients (8 men and 33 women aged 45-70 years) carried out using improved therapeutic and diagnostic algorithms applied to the specifics of the MPL forms and stages. RESULTS: The use of standard protocols of prosthodontic treatment without taking into account the status of oral mucosa in patients with oral LP was associated with the development of nonspecific (prosthetic stomatitis - 25.8%; contact-allergic stomatitis - 22.6%; focal hyperplasia - 16.1%; decubital ulcers - 12.9%, etc.) and oral LP-associated specific reactions (Kebner's symptom - 35.5%; transformation of the typical form into complicated ones - 22.6%; desquamative gingivitis and gingival lichenization - 19.4% each; gum recession - 16.5%) with the involvement of skin and mucous membranes of other localizations (6.5%) and the appearance of symptoms of carcinophobia/dentophobia (25.8%). Prosthetic treatment according to improved protocols for the management of patients with oral LP indicated a decrease in the frequency of nonspecific oral mucosal reactions (by 70.7%, p<0.001), single (4.8%) specific reactions, improvement of masticatory efficiency by 32.8-55.3% (p<0.01), harmonization of speech function, maintenance of a high level of hygiene of prostheses, a significant reduction in the time of adaptation to removable dentures and increased satisfaction with the results of treatment on the GRS scale (1.06±0.3 points after treatment; 3.8±0.5 points before treatment; p<0.001). CONCLUSION: The best dynamics of clinical and sociological indicators was noted in persons with prosthetic replacement structures based on implants.

[Dental decay treatment in hemophilia patients].

Intensive dental decay is a constant symptom in hemophilia patients while its treatment may be challenging because of need for effective but sparing techniques. Rational and safe techniques for dental decay treatment in hemophilia patients are discussed in the study.

[Life quality improvement in hemophilia patients after esthetical teeth restoration].

OBJECTIVE: to study the effect of esthetical teeth restoration on life quality in hemophilia patients. Life quality was assessed by means of adapted OHIP-14 questionary translated into Russian. The study showed life quality to be sensible to dental status: cavities, dental arch defects, poor restorations and dentures. Dental treatment tends to improve life quality in hemophilia patients.
