结局指标
主要结局
Number of Bacterial Colony Forming Units (CFUs)
时间窗: 1 hour from the start of the treatment
At the start of treatment, four agar petri dishes will be placed at standardized distances (2 ft, 3 ft, 4 ft, and 6 ft) from the dental chair headrest in the operating room for one hour. An impinger will also be positioned 2 ft from the headrest for one hour. The number of bacterial colony-forming units (CFUs) will be counted for each petri dish and the impinger after a 72-hour incubation period. The average number of Bacterial CFUs is reported.
次要结局
- Number of Bacterial Colony Forming Units (CFUs) at Each Location(1 hour from the start of the treatment)
