Время чистки зубов составляло 3 минуты. При посеве до применения обнаружен рост факультативно аэробной грамположительной палочки (Bacillus subtilis) и отсутствие условно-патогенной микрофлоры. Через 1 месяц после применения зубных щеток PRESIDENT Exlusive были обнаружены Actinomycetec oralis, Streptococcus Oralis, Lactobacillus salivarius, Str. Vestibularis, которые являются представителями нормальной микрофлоры. У 5 щеток PRESIDENT Exlusive не было выявлено роста микроорганизмов. Через 1 месяц после использования обычных щеток в посевах обнаружены наряду с представителями нормальной микрофлоры условно патогенные микроорганизмы Klebsiella oxytoca, Citrobacter freundii, Pseudomonas putida, Candida albicans.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of studying the microbial contamination of manual toothbrushes and PRESIDENT Exlusive toothbrushes before and 1 month after use in 40 patients aged 27±2.3 years without concomitant somatic pathology (the oral cavity is sanitized, the P constant prevails in the DMF index). The toothbrushing time was 3 minutes. When sowing before use, the growth of facultative aerobic gram-positive rods (Bacillus subtilis) and the absence of opportunistic microflora were detected. One month after using PRESIDENT Exlusive toothbrushes, Actinomycetec oralis, Streptococcus Oralis, Lactobacillus salivarius, Str. Vestibularis were detected, which are representatives of the normal microflora. No growth of microorganisms was detected in 5 PRESIDENT Exlusive brushes. One month after using conventional brushes, opportunistic microorganisms Klebsiella oxytoca, Citrobacter freundii, Pseudomonas putida, Candida albicans were found in the cultures along with representatives of normal microflora.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>зубные щетки</kwd><kwd>микробная обсемененность зубной щетки</kwd><kwd>зубные щетки PRESIDENT Exlusive</kwd></kwd-group><kwd-group xml:lang="en"><kwd>toothbrushes</kwd><kwd>microbial contamination of toothbrushes</kwd><kwd>PRESIDENT Exlusive toothbrushes</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Абдусаламова Б.Ф.
