Abstract
Background: Operator safety during dental & periodontal treatment is a non-negotiable necessity. The production of airborne material, during dental procedures is obvious to the dentist, dental team and the patient.
 Aim: The aim of the present study was to evaluate, the colony forming units (CFU) generated from aerosol during ultrasonic procedure in gingivitis and periodontitis subjects that act as a potential risk factor for spread of infectious agents for both operator and patients.
 Materials and Methods: The present study included 18 subjects which were randomly assigned into 3 equal groups. Group I (Control group) subjects were treated with ultrasonic scaling alone, whereas; Groups II & Group III (Test groups) subjects used pre-procedural mouth-rinses before scaling & root planing (Chlorhexidine and Povidone Iodine). Blood agar plates were used to assess the aerosol contamination and were placed at operator’s eye level, subject’s eye & chest level. These plates were then incubated for 72 hours and microbial growth were quantified as colony forming units (CFU/plate). Different colonies were identified by standard biochemical methods.
 Results: This study showed that the antiseptic mouth-rinses significantly reduce the bacterial CFU in the aerosol. Povidone Iodine was found to be superior to Chlorhexidine when used pre-procedurally.
 Conclusion: The following conclusion was drawn that the use of pre-procedural rinses significantly reduced the aerosol contamination and hence chances of cross-infection in the dental units.
Highlights
Modern dentistry is founded upon a preventive philosophy in which subjects are encouraged to attend regular examination.[1]

Summary
Modern dentistry is founded upon a preventive philosophy in which subjects are encouraged to attend regular examination.[1] Potential problems may be detected at an early stage and appropriate action taken before they become more serious. Treatment of periodontal diseases primarily aims towards the reduction of embedded microorganism in the sub-gingival biofilm. Mechanical debridement of the periodontal pocket has been demonstrated to significantly improve gingival health.[2] there is limited evidence of clinical efficacy and safety, there is a strong trend among clinicians to give preference to ultrasonic instruments for subgingival debridement.[3]. Operator safety during dental & periodontal treatment is a non-negotiable necessity.
