OBJECTIVE: To investigate the effects of instrumentation and ultrasonic treatment on the root canal flora.
METHODS: A total of 21 single-rooted teeth with chronic apical periodontitis were selected and prepared using step-back/ultrasonic technique, Samples were taken before and after the step-back preparation, and after the ultrasonic treatment.
RESULTS: The number and species of bacteria in the root canal were both reduced dramatically and there were significant differences among the three groups (P < 0.05).
CONCLUSION: The instrumentation and ultrasonic treatment of root canal can effectively reduce the number and species of root canal microflora.
