Comparative study of microbial contamination of the working surface of different toothbrushs

Abstract

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.
