Comparison Between the Antimicrobial Efficacy of Herbal and Conventional Toothpaste for Caries Prevention.

Abstract

Background:

Dental caries is one of the most common oral diseases worldwide and is primarily associated with cariogenic bacteria such as Streptococcus mutans. Toothpastes play a crucial role in maintaining oral hygiene by reducing bacterial load and preventing plaque formation. Conventional toothpastes contain chemical antimicrobial agents, while herbal toothpastes use plant-derived phytochemicals with potential antibacterial properties.

Aim:

The present study aimed to compare the antimicrobial efficacy of commercially available conventional and herbal toothpastes against Streptococcus mutans.

Materials and Methods:

An in-vitro study was conducted using agar well diffusion assay to evaluate antibacterial activity. Six different commercially available toothpastes (five conventional and one herbal) were tested against Streptococcus mutans. The zone of inhibition (mm) was measured to determine antimicrobial effectiveness. The experiment was performed in triplicate. Statistical analysis was carried out using SPSS version 21.0 with the Kruskal–Wallis test followed by Bonferroni post hoc analysis, and a p-value < 0.05 was considered statistically significant.

Results:

All tested toothpastes showed antimicrobial activity against Streptococcus mutans. Among the groups, Gopal toothpaste demonstrated the highest mean zone of inhibition (36.67 mm), while the herbal toothpaste Herbodaya showed the lowest (26.33 mm). The differences among the groups were statistically significant (p = 0.007).

Conclusion:

Within the limitations of this in-vitro study, conventional toothpastes exhibited higher antimicrobial efficacy compared to the herbal toothpaste tested. However, herbal toothpaste also demonstrated measurable antibacterial activity and may serve as a natural alternative for maintaining oral hygiene
