An in vitro antimicrobial activity of six commercial toothpastes

Abstract EN

The antimicrobial activity of six different toothpastes Colgate Total, Signal, Crust, Bio fresh, Close up & Miswak were evaluated on some pathogenic oral microorganisms : Streptococcus sp.

(α-hemolytic), Staphylococcus aureus & Candida albicans.

The preliminary antimicrobial activity evaluation was performed using an agar well diffusion method and distilled water was used as controls.

The samples were tested in 0.5, 0.25, 0.125, 0.06, 0.03, 0.01, 0.005, 0.0025 g / ml.

Inhibition zones were measured in millimeter after 24 hr.

All tested toothpastes have antimicrobial activity on bacterial & fungal type but antimicrobial activity on bacteria more than activity on Candida albicans.

Antimicrobial activity of all toothpastes on bacterial types were approach one another.

In conclusion the antimicrobial activity of Colgate Total, Signal & Crust were better than Bio fresh, Close up & Miswak.
