Improving the methods of local treatment in case of aphthous lesions on the oral mucosa
Annotation. Contamination of the oral mucosa ulcers with opportunistic microorganisms aggravates the course of chronic recurrent aphthous stomatitis (HRAC). Topical medicines help to eliminate inflammation rapidly and induce fast epithelization of the mucous membrane defect in patients with HRAC. The aim of the work was to create curative composition recipe for the local therapy at HRAC, resulting to higher effectiveness of antimicrobial therapy and acceleration of healing. 43 patients with HRAC were examined. Samples from the lesions were inoculated blood agar and Sabouraud agar. The conventional methods were used for microorganisms’ identification. The sensitivity of isolated strains to antibiotics and antifungals was determined. Antimicrobial activity of the proposed applicative composition was determined by the well method into agar media. It was established that the surface of patients` lesions on the oral mucosa was most often colonized with associations of Streptococci and Neisseriae, Streptococci and C. albicans. For every third patient, the erosive surface was infected with gram-negative microorganisms, including non-ferments and enterobacteria. Most of the isolated bacteria were highly sensitive to antibacterial compounds. Yeast-like fungi exhibited high resistance to fluconazole, itraconazole, 50% of them were resistant to ketoconazole, and resistance to nystatin were revealed in 81% of isolated strains. The proposed application dosage form containing vinyl, decamethoxin, essential oils of carnation and sea buckthorn had a high antimicrobial activity against isolated strains. Obtained results indicate the feasibility of the applicative composition for treatment of erosive and ulcerative lesions, which are caused by microorganisms, in dental practice.
