| Popis: | Обследованы 47 пациентов 9-15 лет с дистальной окклюзией в процессе ортодонтического лечения. Из биоматериала зубной бляшки в 25 % наблюдений выделены грибы вида Candida albicans на фоне высокого содержания микроорганизмов, как кариесогенной, так и ассоциативной групп (Streptococcus, Enterococcus, Staphylococcus, Neisseria, Micrococcus, Corynebacterium, Klebsiella). Большинство штаммов продемонстрировали выраженную резистентность к 0,01 % мирамистину. Наиболее высокий уровень минимальной подавляющей концентрации по отношению к культурам S. aureus, S. epidermidis, S. haemolyticus и C. albicans определен для 0,1 % хлоргексидина биглюконата. Background. Caries in children undergoing the orthodontic treatment is caused by the complex of adverse factors the most important of which is the microflora of the tooth plaque. Methods. 47 patients of 9-15 years with дистальной окклюзией during the orthodontic treatment in different follow-up period are examined: in 1, 6 and 18 months. Authors studied features of qualitative and quantitative structure of the microbiocenosis of the tooth plaque and estimated the level of sensitivity of microbiota representatives to antiseptics. Results. From the tooth plaque biomaterial in 25 % of cases allocated mycosis of the type Candida albicans together with the high level of microorganisms of the caries-inducing and associative groups (Streptococcus, Enterococcus, Staphylococcus, Neisseria, Micrococcus, Corynebacterium, Klebsiella). The majority of strains have shown the expressed resistance to 0.01 % miramistin. The highest level of the minimum overwhelming concentration in relation to the cultures of S. aureus, S. epidermidis, S. haemolyticus and C. albicans was defined for 0.1 % chlorine hexidine bigluconate. Conclusions. The obtained data allowed showing that orthodontic treatment of children by fixed equipment promotes constant increase in the level of the tooth plaque microbiota and is the important risk factor of caries. Representatives of the microbiota during the treatment can adapt for the specific conditions of existence and increase resistance to some kinds of the antiseptic agents. |
