An In vitro Study to Determine the Antibacterial Activity of Chlorhexidine and Herbal Mouthrinses against Enterococcus faecalis

Abstract

Background: Oral diseases have a strong history of treating by natural remedies. Chemical plaque reduction techniques, including dental mouthwashes, are intriguing because they can help patients who are unable to maintain appropriate mechanical plaque management. They are a less technically difficult alternative to mechanical control. Aim: This study aimed to compare the antibacterial efficacy of an herbal and 0.2% chlorhexidine gluconate mouthrinse against Enterococcus faecalis . Methodology: The antimicrobial effectiveness (zone of inhibition) of an herbal mouthrinse and chlorhexidine mouthrinse was determined by agar well diffusion method. Results: The zone of inhibition for control mouthrinse was 19 mm, and there was no zone of inhibition observed for the experimental mouthrinse. Conclusion: The result of this investigation suggests 0.2% chlorhexidine gluconate has a better antimicrobial activity than herbal mouthrinse.

The Antibacterial and Antifungal Capacity of Eight Commercially Available Types of Mouthwash against Oral Microorganisms: An In Vitro Study

“…Additionally, a meta-analysis by Costa et al [ 19 ] revealed that using mouthwashes that contained a chlorhexidine base reduced the probing depth in patients with chronic periodontitis. This is in addition to several other studies, in which chlorhexidine gluconate was shown to be effective in reducing the virulence of bacteria and yeasts such as E. faecalis and C. albicans [ 14 , 20 , 21 ]. The long-term use of antiseptics may produce a resistance in vivo, due to the exposure to sublethal concentrations that has arisen over the last century [ 22 ].…”

Formulation and assessment of biological properties of garcinia indica fruit extract mouthrinse as an adjunct to oral hygiene regimen: an in vitro analysis

“…Various authors have used Chlorhexidine mouth rinse on diverse oral bacteria and derived similar inferences. 35 , 36 Despite the high efficacy of 0.2% GI and 0.2% CHX in reducing microbial levels from baseline to 12 th hr study time period, the 0.1% Turmeric mouth rinse group also exhibited a decline in microbial colonies during the 6 th to 12 th hr interval. Comparable decline in growth of mature biofilm was documented in a research conducted by Bomdyal, et al 37 (2017) where the antimicrobial properties of turmeric against periodontopathogens were evident at the end of 48 hours.…”
