Análise da efetividade antimicrobiana de marcas comerciais de antissépticos bucais à base de produtos naturais na prevenção de cárie dentária e doença periodontal

Abstract

Introduction: Dental caries and periodontal disease are multifactorial pathologies associated with dental biofilm, potentially leading to tooth loss. Mechanical and chemical control, including the use of antiseptics such as chlorhexidine, is essential for treatment. The use of herbal-based mouthwashes emerges as a promising alternative, with the potential to reduce costs and expand access to oral health care. Objective: To evaluate the antimicrobial efficacy of commercially available herbal mouthwashes in the prevention of dental caries and periodontal disease. Methodology: Minimum inhibitory concentration (MIC) tests were performed using serial dilution in 96-well plates for S. aureus and S. mutans strains, along with inhibition zone tests on Petri dishes. Results: Chlorhexidine digluconate 0.12% showed lower variance in MIC values and inhibition halos for both strains. Among herbal mouthwashes, Malvatricin Plus was more effective against S. aureus, while Suavetex showed insignificant results for both strains. Conclusions: Chlorhexidine 0.12% confirmed its superiority as the antimicrobial gold standard, whereas herbal mouthwashes showed variable efficacy depending on the bacterial strain.
