Most participants store their toothbrushes in the bathroom after use but only 5% store them outside the bathroom. Ten different bacterial strains were isolated from 182 toothbrushes and one type of yeasts, Candida Spp. was identified. Neisseria spp. and Staphylococcus epidermidis were shown to be present in all groups regardless the toothbrushes storage method. Whereas Streptococcus viridans, Bacillus spp., Klebsiella pneumoniae, and Enterobacter agglomerans have been identified solely in specific groups only.

Conclusion(s): The participants showed satisfactory standards of oral hygiene habits and definitely in need of raising the awareness of implementing better oral health. Soaking the toothbrush in chlorhexidine shown to be the best storage method in terms of the presence of bacterial strains.
