Abstract

Background:

Dentin hypersensitivity (DH) is a frequent condition in adults and difficult to treat. The aim of this single-blind, randomised controlled clinical trial was to investigate immediate and long-term effect of ozone treatment (Prozone, W&H NORDIC AB) for 12 seconds on hypersensitive teeth compared to placebo treatment, using a split-mouth design.

Methods:

26 patients (12 M, 14 F, mean age 44+ 2) were included in the study having at least two teeth with confirmed DH in different quadrants of the dentition (each subject had one test and one control tooth). A visual analogue scale (VAS) was used to measure the patients´ pain perception immediately and at a long-term follow-up three months later.

Results:

Significant reduction in pain perception from DH surfaces was demonstrated from ozone treated test teeth as well as in placebo treated control teeth. We found a moderate (16.2%) but significant pain relief (p< 0.012) over time in 57.7% of all treated teeth.

Conclusion:

Results from this study confirm previously published results showing no significant effect of ozone treatment on hypersensitive teeth compared to placebo treatment.
