Effectiveness of Pre-Procedural CPC and Zinc Mouthwash in Reducing Dental Aerosols
Sponsor: Colgate Palmolive
Summary
This clinical trial evaluates the effectiveness of pre-procedural mouthwashes in reducing bacterial contamination in dental aerosols generated during ultrasonic scaling. Participants undergo a single-day clinical visit where they receive a randomized pre-procedural rinse (or control) followed by full-mouth ultrasonic prophylaxis. Viable bacteria in aerosols collected on agar plates surrounding the dental unit are measured to determine whether rinsing with an alcohol-free mouthwash containing 0.09% Cetylpyridinium Chloride (CPC) and 0.28% Zinc Lactate significantly lowers bacterial contamination compared to water, no rinse, or a 0.2% Chlorhexidine positive control.
