An Herbal Alternative to Control Nosocomial Pathogens in Aerosols and Splatter During Ultrasonic Scaling

Abstract

Objective: To evaluate the efficacy of herbal mouthwash (Himalaya Hiora Regular) against methicillin-resistant Staphylococcus aureus and Acinetobacter baumanni during ultrasonic scaling. Material and Methods: Group B (n=25) received herbal mouthwash and Group A (n=25) received 0.12% chlorhexidine mouthwash respectively as a preprocedural rinse. The aerosols produced by the ultrasonic unit were collected on MeReSa and Leeds Acinetobacter Agar plates. The experimental setting included eight different locations covering all areas of the operatory. The plates exposed to aerosols for a period of 30 minutes were incubated aerobically at 37 o C for 48hrs and the colony forming units (CFU) were statistically analyzed. Results: Herbal mouthwash (Himalaya Hiora Regular) showed a significant reduction in mean CFU of MRSA compared to 0.12% chlorhexidine. While herbal mouthwash was on par with 0.12% chlorhexidine in the reduction of A. baumannii . Conclusion: Herbal mouthwash was found to be more effective against MRSA than 0.12% Chlorhexidine mouthwash as a pre-procedural rinse. Both herbal mouthwash and chlorhexidine mouthwash was found to be effective against A. baumannii . Herbal mouthwash may be a safe alternative to chlorhexidine against nosocomial pathogens like MRSA and A. baumannii .
