Abstract :
The present study was carried out to evaluate antibacterial activity of toothpastes, which were available in local
market. A total 15 samples were collected for isolation of cariogenic bacteria. The bacterial strains were
isolated by using selective Medias and identified on the basis of cultural, morphological, biochemical
characteristics. The bacterial strains resistant to various choosen antibiotics subjected to action of toothpaste.
Aqueous solutions of toothpastes were tested against dental caries bacteria. The distilled water suspension of
toothpastes were found to has remarked antibacterial properties.in the current study total 7 brands of
toothpastes used and labeled as T1-T7.The effectiveness of toothpaste was reported based on zone of growth
inhibition against cariogenic bacteria. Toothpastes T3and T7 showin g broad spectrum of action against
antibiotic resistant strains of Pseudomonas spp, Streptococcus spp., Staphylococcus aureus. And Lactobacillus
spp.T1 is also effective against all selected strains of cariogenic bacteria. But T1 was comparatively less
effective as compared to T3and T7. T3and T7 toothpastes are herbal. Other selected toothpaste T2, T4, T5 and
T6 are ineffective against cariogenic strain of Streptococcus spp. This study shown herbal toothpastes have
more antibacterial activity against selected strains of antibiotic resistant cariogenic bacteria like., To reduce
the dental problem herbal based toothpastes should be recommended.
