In-vitro Assessment of the Antibacterial Quality of Some Commonly Used Herbal and Non-herbal Toothpastes on Streptococcus mutans

Abstract

In-vitro assessment of the antibacterial quality of four commonly used brands of herbal toothpastes in comparison with their corresponding non-herbal toothpastes on Streptococcus mutans was examined. Eight brands of commercially available toothpastes comprising of four herbal and non-herbal brands respectively were purchased in a local market in Awka South, Anambra State, Nigeria. The herbal brands selected were designated AH, BH, CH and DH and their respective non-herbal brands designated ANH, BNH, CNH and DNH served as positive controls. The use of distilled water served as negative control. The antibacterial activity evaluation was performed using agar well diffusion method. Different concentrations of toothpastes were made by 2-fold serial dilution method using sterile distilled water as diluents. Inhibition zones were measured in millimeters after 24hrs. Among the non-herbal toothpastes, triclosan containing toothpaste gave the highest zone of inhibition compared to non-triclosan toothpastes. The herbal toothpaste of each brand gave better inhibition result in comparison with their corresponding non-herbal brands. BH toothpaste gave maximum inhibition followed by AH, CH and lastly DH toothpastes. The result of this study indicates that herbal toothpastes are marginally better in inhibiting the growth of Streptococcus mutans; although both herbal and non-herbal toothpastes were equally effective in reducing pathogenic plaque and maintaining oral hygiene.

Phytochemical and Antibacterial Activities of Ocimum Gratissiumum L. on Isolates from Kunu-Zaki

“…Antimicrobial activity screening was conducted using the modified agar well diffusion method, following the procedure outlined by (Agu et al, 2013;Agu et al, 2014;Awah et al, 2016;Adindu et al, 2017;Awah et al, 2017;Saeed and Tariq, 2017;Ubaoji et al, 2020). Duplicate plates of Mueller-Hinton Agar (MHA) were prepared, with 20 ml poured into each sterile Petri dish and allowed to solidify.…”

Qualitative and Quantitative Phytochemical Analysis of the Ethanolic and Aqueous Extracts of Solanum nigrum L.

“…Plants have been utilised as medicine for many years because they are a rich source of physiologically and therapeutically active compounds (Awah et al, 2016;Awah et al, 2017;Ubaoji et al, 2020). These plants have been linked to the treatment of a variety of diseases, although some of them may have negative effects on the body (Agu et al, 2013;Agu et al, 2014;Adindu et al, 2016).…”
