Ozone water for sterilization of root cannals Determination of concentration of ozone generated by a novel ozone generator

AIM:To determine the ozone concentration in irrigation and sterilization of the root canal and to investigate the changes of ozone concentration.METHODS:Ozone concentration was determined after formation every(5 min) for 40 min using iodine titration.At the same time a blank group was set up.RESULTS:Ozone concerntration increased with time.At 35 minutes it reached the maximum(1.334),and later declined.CONCLUSION:The ozone concentration curve of a new type of ozone water machine was determined,which would be useful for the further study.
