RESUMEN
PURPOSE OF THE STUDY: To study the effectiveness of the drug Cholisal as part of the conservative treatment of chronic periodontitis. MATERIAL AND METHODS: We selected 100 patients aged 35 to 65 years of both sexes with a diagnosis of moderate chronic periodontitis in the acute stage with a periodontal pocket depth of 3.5-5 mm. Depending on the tactics of conservative treatment of periodontitis, patients were divided into two groups of 50 people. In the main group, Cholisal dental gel was used as part of complex conservative treatment, and in the control group, Metrogil-denta gel was used. To assess the effectiveness of treatment, a dental examination of patients was carried out with an index assessment of the condition of periodontal tissues and a biochemical analysis of the content of arachidonic acid and prostaglandin E2 in gingival blood, comparing the indicators before treatment and 14 days after the start of treatment. RESULTS: When the drug Cholisal was included in complex treatment, 14 days from the start of treatment, patients experienced a statistically significant decrease in the depth of periodontal pockets from 4.7±0.32 mm to 3.6±0.19, and the Green-Vermillion hygiene index by 60.7%, Silness-Loe plaque index by 73.1%, PMA index by 68.8%, Muhlemann-Cowell bleeding index by 68.0% (p<0.001 compared to baseline). When Metrogil-denta gel was used in complex therapy, the effectiveness of treatment was lower: the depth of periodontal pockets did not change significantly (from 4.5±0.22 mm to 4.2±0.17 mm, p>0.05), reduction in the hygiene index Green-Vermillion was 51.9%, Silness-Loe plaque index - 64.0%, PMA index - 43.7%, Muhlemann-Cowell bleeding index - 45.8% (p<0.001 compared to baseline, p<0.001 compared to the main group). A laboratory study showed that in patients of the main group, after completing a course of conservative treatment, the content of biomarkers of inflammation significantly decreased compared to the initial level (p<0.05), while in patients of the control group the content of arachidonic acid and prostaglandin E2 in the gingival blood during the study period did not change significantly (p>0.05 compared to the initial level). CONCLUSIONS: The use of the drug Cholisal in the conservative treatment of chronic periodontitis has demonstrated more pronounced positive dynamics of clinical and biochemical parameters compared to traditional therapy, which suggests its high effectiveness.

OBJECTIVE: The aim of the study. Improving the efficiency of diagnosis and detailing the features of the clinic of «potentially malignant¼ diseases of the oral mucosa. MATERIALS AND METHODS: Clinical and laboratory examination of 124 patients of the department of oral mucosa diseases aged 35 to 80 years, among whom there were 75 women and 49 men, with diseases such as erythroplakia - 12 patients, verrucous leukoplakia - 52 patients, erosive form of leukoplakia - 35 patients, cheilitis Manganotti - 25 patients. Histological and immunohistochemical methods of investigation were used as diagnostics. To assess the proliferative activity of epithelial cells, the determination of the Ki-67 index was used. The synthesis of keratin 15 (K15) in epithelial layers was determined as a diagnostic criterion for the severity of neoplasia. The expression of human papillomavirus type 16 (HPV 16) antigens and p16INK4a protein in epithelial cells was studied, as well as the expression of p53 protein. RESULTS: A high prevalence of p53 mutations was observed in patients with erythroplakia. In leukoplakia, the expression of the Ki-67 protein was detected in the cell nuclei in both the basal and parabasal layers of the multilayer squamous epithelium, in 77% of cases, the expression of the p16INK4a protein in the epithelial nuclei with varying degrees of dysplastic changes was noted, and a positive reaction to HPV16 was also observed in the cell nuclei and cytoplasm of epithelial cells in the basal, parabasal and spiny epithelial layers. The appearance of K15 in the cytoplasm of cells above the basal layer with abrasive precancerous cheilitis was found in 48% of cases. CONCLUSION: To diagnose early manifestations of neoplastic processes in «potentially malignant¼ diseases of the oral mucosa, it is necessary to use both classical histological and immunohistochemical methods of investigation with various markers.

THE AIM OF THE STUDY: Was to explore the accumulation and distribution of the photosensitizer Photoditazine in the oral mucosa when applied to pathological lesions in patients with severe forms of lichen planus. MATERIAL AND METHODS: A clinical and laboratory examination was carried out in 50 patients with severe forms of lichen planus (bullous and erosive-ulcerative) aged 18 to 70 years, including 6 men and 44 women. For autofluorescent imaging a LED device with a wavelength in the violet region of the spectrum (400±10 nm) was used. Quantitative registration of the kinetics of accumulation and distribution of the photosensitizer was carried out using the method of local fluorescence spectroscopy by measuring the fluorescence spectra. RESULTS: The measurements were made before applying the photosensitizer, 10, 20 and 30 minutes after application. The study showed that in most patients with erosive-ulcerative and bullous forms of lichen planus, the accumulation of the photosensitizer in the lesions on the oral mucosa increased as the exposure time increased from 20 to 30 minutes. The fastest accumulation of the photosensitizer occurred in the areas of mucosal lesions with the most pronounced vascularization, namely, in the area of the tongue and the bottom of the oral cavity. CONCLUSION: Using the method of local fluorescence spectroscopy, the kinetics of accumulation and destruction of photosensitizer in pathological areas of the oral mucosa was determined, and therefore the optimal time of laser exposure to the lesion was determined.
