Effectiveness of 0.2% chlorhex plus and 0.1% turmix as preprocedural mouthrinses on aerosol contamination produced by ultrasonic scalers: An interventional study

Objective: Dental handpieces, ultrasonic scalers, air polishers, air abrasion units produce the most visible aerosols. The objective of this study was to assess the effectiveness of Chlohex Plus and Turmix as preprocedural mouthrinses on aerosol contamination produced by ultrasonic scaler inside the Mobile Dental Unit. Materials and Methods: A total of 30 patients were included in this study, they were randomly assigned into two groups and were subjected to scaling before and after rinsing with 0.2% CHX,0.1% turmix. Blood agar plates were used to collect the gravitometric settling of aerosols and were sent for culture. Results: The mean CFU/mL of the anaerobic bacteria from the aerosol generated after pre-rinse with TRX was found to be less than 50% of the mean effective pre-rinse CHX threshold. The TRX pre-rinse was found to be more effective than the CHX pre-rinse. Bacteriodes spp. and the Peptostreptococcus spp. were the most common anaerobic pathogen isolated from the aerosol tested which is strongly suggestive of aerosol were directive from patient sample only. Conclusion: Hence the consideration of routine use of CHX and turmix mouthwash as prior to all dental procedures results in the reduction in number of oral bacteria available for possible induction of bacteremia or dissemination to the attending dentist and other personnel.
