Ozone treatment had no effect on tooth hypersensitivity

Ozone Treatment on Dentin Hypersensitivity Surfaces – A Pilot Study

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 ...

Tooth brushing, tooth wear and dentine hypersensitivity--are they associated?

Evidence suggests that patients suffer the painful symptoms of dentine hypersensitivity when dentine is exposed and the dentinal tubule system is opened to the oral cavity to allow stimuli to trigger a neural response in the pulp via a hydrodynamic mechanism. The processes needed to localise lesions of dentine hypersensitivity include loss of enamel and/or gingival recession. Whilst tooth brush...
