Materials and Methods: An experimental study was conducted to assess the effect of antimicrobialpre-procedural rinsing on aerosols in the dental office on 10 patients with mild to moderate gingivitisbetween the age group of 25 to 40 years which was followed by a questionnaire survey done among 193dental students to assess their level of knowledge and attitude towards aerosol contamination and isolation. Results: The reduction in the CFUs of aerosols after the use of antimicrobial mouth rinse wasstatistically significant {p<0.003}. Among the 193dental students, 51 (26.4%) had low level of knowledge,131 (67.8%) had acceptable level of knowledge and 11 (5.8%) had high level of knowledge. The levelof knowledge gradually increased with the year of study {p<0.001}.Conclusion: In our study we observed that Antimicrobial Pre - procedural mouthrinse containing 0.2%Chlorhexidine gluconate was effective in reducing viable bacteria in oral spatter and the level of knowledgeamong the dental students regarding aerosol contamination and isolation gradually increased with the yearof the study.
