Abstract

Background:  In dentistry, Ultrasound was first used for preparation of cavities. In comparison to sonic irrigation, ultrasonic irrigation has proved to be more powerful and able to eliminate more debris, and so it is claimed that passive ultrasonic irrigation is significantly more efficient than sonic activation. Hence; we planned the present study to evaluate the antimicrobial efficacy of sodium hypochlorite in passive method of irrigation and active ultrasonic method. Materials & methods: The present study included assessment of antimicrobial efficacy of different irrigating solutions using ultrasonic device. A total of 40 freshly extracted mandibular first premolars were used in the present study. Division of all the tooth samples was done randomly and broadly into two study groups: Group A- Included samples that received 2 ml of 2.5% NaOCl irrigation after each instrument used for canal preparation Group B: Extra agitation of the irrigant with a file #15 fitted on to Generic Ultrasonic Scaler Handpiece VDW. All the samples were collected by paper points and were sent to laboratory in appropriate transporting media were they were streaked in Sabaraud dextrose medium and MacConkeys medium for assessing the antimicrobial efficacy. All the results were summarized in Microsoft excel sheet and were analyzed by SPSS software. Results: Significant results were obtained while comparing the mean CFUs of S. mutans, C.albicans and E.faecalis among Group A and Group B.  Conclusion: Antimicrobial efficacy of irrigation solutions is increased by the used of ultrasonic devices.
