Comparison of efficacy of 0.05% sodium hypochlorite with 0.2% chlorhexidine as A pre-procedural mouthrinse in periodontitis patients

Abstract

: The objective of the study is to compare the efficacy of 0.05% sodium hypochlorite and 0.2% chlorhexidine as a pre-procedural mouth rinse for routine periodontal procedures to reduce the amount of aerosols containing infectious agents. A study was designed to be conducted on patients reporting to the outpatient department of Periodontology at Buddha Institute of Dental Sciences & Hospital, Patna. Patients with generalized severe chronic periodontitis were divided into 3 groups. 15 patients were made to rinse with 0.05 % sodium hypochlorite for 1 minute, (Group A), 15 patients with 0.2% chlorhexidine (Group B), and 15 patients with normal saline (Group C) for 1 minute before routine ultrasonic scaling procedure. A blood agar plate exposed at 20 inches from the patient’s oral cavity was used for microbial sampling. It was incubated at 27°C for 24 hours and colony forming units (CFUs) were counted thereafter.: There was statistically significant differences in the number of CFUs of the different groups.: Both 0.05% sodium hypochlorite and 0.2% chlorhexidine were effective in reducing aerosol contamination during ultrasonic scaling but 0.05% sodium hypochlorite had a significantly better effect than 0.2% chlorhexidine.
