RESUMO
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.

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.

OBJECTIVE: To evaluate the initial molecular genetic signs of malignancy of verrucous leukoplakia (VL). MATERIALS AND METHODS: The study of VL was carried out on biopsies of 21 patients with the diagnoses of verrucous hyperplasia (VH) (15 cases - 71.4%) and verrucous carcinoma (VC) (6 cases - 28.5%). Tissue antigens were determined using mouse monoclonal antibodies to the Ki-67 protein (MM1, Diagnostic Biosystems). Telomerase activity was determined using rabbit immunoglobulin (TRT, Abbiotec). The amplification of the TERC (Telomerase RNA Component) portion of the RNA of the third chromosome was studied by the FISH method. RESULTS: In the studied groups, high cell proliferation and significant differences between HC and VC were revealed. The amplification of TERC by the FISH method made it possible to carry out differential diagnostics between VG and VC. According to the results of the study, the amplification of the TERC gene was detected in 100% in VC and in 20% in VG. CONCLUSION: The FISH method makes it possible to detect VL malignancy at an early stage. Amplification of the TERC gene is characteristic of malignant transformation of epithelial cells in VC. In IG, as a rule, there was no amplification, which can serve as evidence of the benign nature of the pathology of COP.

External cervical tooth root resorption is one of the most aggressive types of pathological resorption. Due to the uncontrolled growth of resorptive tissue, irreversible loss of dentin and cement occurs. To date, there is no common position regarding the etiological factor and pathogenesis of invasive cervical resorption. The histological picture is similar to some fibro-bone lesions. The treatment outcome of the pathology is difficult to predict because elimination of the causative factor is often not sufficient for resorption arrest. Only the complete elimination of resorptive tissue helps to stop the process. The report describes a clinical case of a successful treatment of invasive cervical resorption of dental hard tissues.

OBJECTIVE: The aim the study is to increase the effectiveness of the treatment of severe forms of leukoplakia with the use of photodynamic therapy. MATERIAL AND METHODS: 120 patients with severe forms of leukoplakia were examined. 30 patients were diagnosed with Cr and carcinoma in situ, and therefore they were excluded from the study. In 90 patients, the diagnosis was confirmed by histological and IHC studies. Before the use of photodynamic therapy, the degree of saturation of pathological foci with a photosensitizer was determined by the method of fluorescent diagnostics using the LED device «RFS-400¼. RESULTS: As a result of treatment with photodynamic therapy using a 2nd generation photosensitizer («Photoditazine¼ 0.5% gel penetrator), a significant improvement in the epithelization of lesion elements was observed: in 92% of patients with verrucous leukoplakia and in 83% of patients with erosive leukoplakia. CONCLUSION: The use of photodynamic therapy for the treatment of patients with complicated forms of leukoplakia is an effective method of treatment for this pathology.

Aphthous stomatitis (AS) is one of the most common diseases of the oral mucosa in children. A significant role in the pathogenesis of AS is assigned to the infectious-allergic factor. THE AIM: Of the work was to evaluate the clinical effectiveness of topical application of bacteriophages in the complex treatment of children with aphthous stomatitis. MATERIALS AND METHODS: The main group included 30 children with AS aged 4 to 15 years. The control group consisted of 20 healthy children without AS and without concomitant somatic pathology at the age of 4 to 15 years. The effectiveness of the therapy was evaluated based on the results of repeated bacteriological examination of the oral microflora, conducted 1 month after phage treatment, as well as the dynamics of clinical manifestations: reduction in size or complete epithelization of defects. RESULTS: The use of bacteriophage in the complex treatment of children with AS was accompanied by positive dynamics of clinical and laboratory parameters in all patients: a significant decrease in microbial contamination and the number of individual pathogenic microflora species against the background of normalization of local microbiocenosis in the oral cavity. CONCLUSION: The obtained clinical and laboratory data allowed improving the scheme of complex treatment of AS in children by the use of bacteriophages.

OBJECTIVE: To optimize the identification of precancerous diseases of the oral mucosa, such as Manganotti's abrasive precancerous cheilitis and erythroplakia of the oral mucosa using markers Ki-67 and keratin 15. MATERIAL AND METHODS: The study group included 17 patients with Manganotti's abrasive precancerous cheilitis and 8 with erythroplakia of the oral mucosa. A histological analysis was carried out to scrutinize the biopsy material of the oral mucosa of the patients. Ki-67 protein and keratin 15 were used to assess the proliferative activity of epithelial cells and the severity of neoplasia. Results. Thirteen patients with Manganotti's cheilitis had dysplasia of varying degrees, and 4 had signs of malignancy. A high proliferative activity of the Ki-67 protein was found in the stratum basal and stratum spinosum of the epithelium. In 5 patients with erythroplakia, according to histological examination, grade 2-3 intraepithelial neoplasia was revealed and 3 patients had cancer in situ. The expression of keratin 15 in all patients with Manganotti's abrasive precancerous cheilitis and erythroplakia in the basal layer tended to decrease with an increase in the degree of dysplasia, however, the appearance of keratin 15 in the cytoplasm of cells located above the basal layer was discovered. CONCLUSION: The use of Ki-67 protein and keratin 15 as immunohistochemical markers in the study of diseases such as Manganotti's abrasive precancerous cheilitis and erythroplakia of the oral mucosa makes it possible to identify the initial signs of malignancy more accurately in the epithelium.

OBJECTIVE Based on the data available in modern literature, to conduct a study on the epidemiology, etiology and pathogenesis of bullous lesions of the oral mucosa (pemphigus vulgaris, pemphigoid bullosa, lichen ruber planus). MATERIAL AND METHODS: The article is based on the study of materials of foreign and domestic research databases Pubmed and Elibrary. Used literature data over the past 15 years. RESULTS: According to domestic and foreign studies, among dermatological diseases, the most frequently detected diseases are: lichen ruber planus, pemphigoid bullosa and pemphigus vulgaris. The initial signs of these diseases are often neglected, both in patients and doctors, which leads to irreversible changes and severe course of the pathological process. In this connection, the number of patients with these lesions of the oral mucosa increases every year in all countries of the world. Bullous lesions of the oral mucosa are inflammatory and destructive diseases characterized mainly by recurrent course, variety of clinical manifestations, resistance to various therapeutic drugs. The specific features of the course of these diseases are explained both by the anatomical and physiological features of the oral mucosa, and by the etiologic and pathogenetic mechanisms of development. Currently, autoimmune processes play a leading role in the genesis of diseases, developing in response to changes in the antigenic structure of epidermal and epithelial cells under the influence of various damaging agents. CONCLUSION: Thanks to the study, it was found that currently there are no data confirming the presence of microbial contamination of the tissues of the oral mucosa in the pathology under study. Not enough information on the factors of the immune response, in particular, on proinflammatory cytokines in the tissues of the oral mucosa.

The aim of the study was to assess root canal dentinal walls structure after photodynamic exposure with the use of 0.5% photoditazine. A root canal dentin of 46 single root intact teeth removed for orthodontic indications was examined by scanning electron microscope JEOL JSM-6510 (Japan). Microphotographs of the root canal wall were obtained in the orifice, central and apical parts under×2000 magnification. It was found that photoactivation of 0.5% gel photoditazine by a light source, laser or diode, with a wavelength of 635-660 nm and a power of 150-200 mW is an effective technique for removing the smear layer of the root canal wall, which facilitates the maximum opening of the dentinal tubules to a depth of 2-3 µm. The best result (the maximum number of open dentinal tubules, the absence of a smear layer) is observed with 3 min photoditazine exposure and 2 min of laser exposure. The method can be proposed as an alternative supplement to the conventional root canals irrigation.

The aim of the study was to prove the rationale for antiviral therapy combined with surgical procedures for treatment of severe oral leukoplakia. Complex clinical and laboratory evaluation and treatment was performed in 56 patients divided in 2 groups. Control group was presented by 13 patients receiving dental treatment, local and systemic keratoplastic formulations. Main group involved 43 patients in which conventional treatment protocol was completed by antiviral therapy and surgical procedures. Leukoplakia diagnosis was based on clinical findings, histological and immunohistochemical studies as well as optic coherent tomography data. The obtained results evidently prove the necessity for including antiviral therapy and surgical procedures in treatment scheme of severe oral leukoplakia.

Immunohistochemical examination of the proliferative activity of cells was made investigating the expression of Ki-67 protein and the location of proteins associated with epithelial cell papillomavirus infection involving P16(INK4a) and HPV16 proteins in different cell areas of the intact mucosa, in leukoplakia with the signs of hyperplasia and dysplasia, and in squamous cell carcinoma. There was a positive correlation between the proliferative activity of cells in the parabasal cell areas and the expression of P16(INK4a) protein in oral leukoplakia with the signs of hyperplasia (r(s)=0.397; p=0.018). In oral leukoplakia with dysplastic changes, there was a positive correlation between the proliferation of cells in the parabasal and prickle cell layers and the location of HPV type 16 antigens (r(s)=0.515; p=0.041 and r(s)=0.651; p=0.006). Detection of papillomavirus infection in leukoplakia can solve not only the problems with its genesis, but this is also a morphological basis for the effective prevention and treatment of this common oral mucosal disease.
