Abstract

Background:  Aerosol production during ultrasonic scaling is a potent source of infection. This has become more of a concern during the present nCoV-19 pandemic outbreak to prevent cross-infection. Preprocedural mouthrinsing has been found effective in reducing the bacterial load of the generated aerosol. The aim of the present study was to evaluate and compare the efficacy of two different types of mouthwash containing Chlorhexidine & Herbal Extracts used preprocedural in reducing the bacterial load of the aerosol produced during ultrasonic scaling. Materials and Methodology: 60 subjects reporting to the OPD and requiring ultrasonic scaling were randomly divided into three groups on the basis of agents used - Group I: Distilled Water (Control), Group II: Chlorhexidine (C), Group III: Herbal Extracts (H). Three sterilized blood agar plates were placed at three different positions in the previously fumigated operatory to collect aerosols. The plates were subjected to incubation for 48 hrs, and the Colony Forming Units (CFU) was counted. Result: The mean CFU were recorded highest for Group I patients followed by Group III and Group II patients at all the positions. Conclusion: In the present study, 0.2 % chlorhexidine was found to be the most effective preprocedural agent for reducing the bacterial load in the aerosol followed by herbal mouthwash.
