The aim of this pilot study is to evaluate and compare the efficacy of commercially available preprocedural mouthrinses containing 0.2% chlorhexidine gluconate, an herbal mouthwash, and water in reducing the levels of viable bacteria in aerosols.<\/jats:p><jats:p><jats:bold>Methods:<\/jats:bold> This single\u2010center, double\u2010masked, placebo\u2010controlled, randomized, three\u2010group parallel design was conducted over a period of 45 days. Twenty\u2010four patients with chronic periodontitis were divided randomly into three groups (A, B, and C) of eight patients each to receive 0.2% chlorhexidine gluconate, herbal mouthwash, and water, respectively, as a preprocedural rinse. The aerosol produced by the ultrasonic unit was collected at patient's chest area, doctor's chest area, and assistant's chest area on blood agar plates in all three groups. The blood agar plates were incubated at 37\u00b0C for 48 hours, and the total number of colony\u2010forming units (CFUs) was counted and statistically analyzed.<\/jats:p><jats:p><jats:bold>Results:<\/jats:bold> The results showed that CFUs in groups A and B were significantly reduced compared with group C, <jats:italic>P<\/jats:italic> &lt;0.001 (analysis of variance). Also, CFUs in group A were significantly reduced compared with group B, <jats:italic>P<\/jats:italic> &lt;0.05 (independent <jats:italic>t<\/jats:italic>\u2010test).
