NCT07900958
Bacterial Mask Contamination in Operating Room
The primary objective of this study is to determine whether surgical mask configuration policy-compliant (up or off ) versus mask dangling is associated with differences in bacterial contamination among unscrubbed operating room personnel at Atrium Health Wake Forest Baptist Hospital.

Effectiveness of Pre-Procedural CPC and Zinc Mouthwash in Reducing Dental Aerosols
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.
