- Abstract
Introduction and objective: Dental toothbrushes can serve as reservoir to translocation of periodontopathic bacteria. The aim was to determine periodontal bacterial contamination in both types of toothbrushes, with and without antibacterial bristles. Materials and methods: We included 20 patients with periodontitis, which brushed two randomly selected quadrants with antibacterial brush and the 2 contralateral quadrants with normal toothbrush with modified Bass technique, and thereafter, the brushes were washed with water for 10 seconds and stored in sterile bags at room temperature. At 0, 4 and 24 h bristles were cut from each brush 4 and suspended in the dilution medium VMGA I. These were plated on 3 culture media in anaerobiosis and CO2 and identified according to the colony morphology and further tests such as UV fluorescence, catalase and identification system RAPID ANA II. Normality of the quantitative variables was assessed and compared the number of CFU/ml in the culture media to different culturing times, by the nonparametric Mann Whitney U test with a significance level of p <0.05. Results: There were significant differences in the number of CFU / ml in blood agar at 24 hours of culture (p = 0.011). Were identified from cultures at 3 times bacteria like Porphyromonas gingivalis, Prevotella intermedia/nigrescens, Fusobacterium spp and Eikenella corrodens, while Tannerella forsythia, Eubacterium spp and enteric bacilli were recovered only in the immediate culturing. Conclusion: Both types of brushes had bacterial contamination in the different culture media tested.
