Comparative Evaluation of Cocoa Bean Husk, Ginger and Chlorhexidine Mouth Washes in the Reduction of Steptococcus Mutans and Lactobacillus Count in Saliva: A Randomized Controlled Trial.

Abstract

IntroductionDental caries is a ubiquitous bacterial infection that has afflicted people for years. Streptococci mutans (S. mutans) are markers of dental caries and the population of S. mutans in the saliva is directly related to the number of surfaces colonized by them. Any intervention that can inhibit their growth and survival will negatively impact the initiation and progress of caries. Various antimicrobial agents have been tested against these microorganisms. The goal of this study was to assess the efficacy of cocoa bean husk, ginger, and chlorhexidine mouth rinse on S. mutans and Lactobacillus.Materials and methodsWe conducted a randomized controlled trial involving patients aged 18 to 25 years from July to September 2018. The study population was allocated into three groups. Each group received either cocoa bean, ginger, or chlorhexidine mouth rinses. The study followed a Latin square design. Study participants were instructed to use the assigned mouth rinse once daily for seven days. We collected saliva samples to measure S. mutans and Lactobacillus populations.ResultsCocoa bean husk and chlorhexidine rinses produced a significant reduction of S. mutans (p < 0.05). The ginger-based rinse significantly reduced the Lactobacillus population (p < 0.05).ConclusionOur findings indicate these natural mouth rinses offer promising anticariogenic and antiplaque efficacy as cost-effective alternatives to traditional mouth rinses.
