Description: The effect of an ozone delivery system [HealOzone (KaVo GmbH)] in reducing dentin hypersensitivity (DH) was evaluated.Conclusion. The effect of treatment of hypersensitive teeth with ozone reduces the pain sensation, but this effect cannot be distinguished from the placebo treatment. In this study there was a large placebo effect that narrowed the range over which to detect treatment differences.Results. No subjects reported an increase in pain or any adverse effect. All subjects reported a clinically significant reduction of pain at each follow-up relative to baseline; however, the difference between the study groups was not statistically significant.Methods. An eight-week, three-visit, double-blinded, randomized controlled clinical trial using two HealOzone machines (ozone/air) involving 44 subjects was conducted. The pain, stimulated by tactile and desiccation, was assessed using a 100 mm Visual Analogue Scale (VAS). Also, the global subjects' perception of sensitivity was assessed at each visit using the VAS.
