Ozone treatment had no effect on tooth hypersensitivity

Abstract

Design: This was a randomised controlled trial.

Intervention: Ozone treatment was delivered by HealOzone machines, one delivering air (control) and the other ozone (test), prepared and coded by the manufacturer (HealOzone; KaVo, Biberach, Germany).

Outcome measure: Pain in response to a tactile stimulus or desiccation was assessed using a 100-mm visual analogue scale (VAS). Also, the global subject's perception of sensitivity was assessed at each visit by using a VAS.

Results: No subjects reported an increase in pain or any adverse effect. All subjects reported a clinically significant reduction in pain, relative to baseline, at each followup visit. The difference between the study groups was not statistically significant, however.

Conclusions: Treatment of hypersensitive teeth with ozone reduces the pain sensation, but this effect cannot be distinguished from the placebo treatment. There was a large placebo effect that narrowed the range over which treatment differences might be detected.
