The antibacterial activity of amchur (dried pulp of unripe Mangifera indica) extract (50% ethanol) was tested against ten bacterial strains causing dental plaque by agar well diffusion method. The crude extract showed a broad spectrum of antibacterial activity inhibiting both the groups of Gram-positive & Gram-negative bacteria. The extract was most effective against Bacillus sp., followed by Staphylococcus mutans and Pseudomonas sp., whereas Halobacterium sp. was found to be the most resistant. Chlorhexidine (present in mouthwashes to prevent infection of dental caries) was used as a positive control. Natural extract of amchur was found to be more effective as compared to chlorhexidine. This study shows the potential of amchur in the treatment of dental caries.
