Dr. Edward Lynch (Dental) and co-workers have published in the current issue of Quintessence International a paper titled “Randomized Clinical Trial on the Comparison of Bleaching Outcomes Using either Ozone or Hydrogen Peroxide”.

This randomized, double-blinded clinical trial conducted at the University of Jordan evaluated the efficacy of in-office tooth whitening following application of either ozone or hydrogen peroxide.

Similar bleaching outcomes and lighter tooth shades were obtained following in-office bleaching with either 60 seconds of ozone or 20 minutes of hydrogen peroxide. Notwithstanding, tooth sensitivity was significantly increased following bleaching with peroxide in comparison to ozone. Ozone obviously does reduce the regularly clinically observed inconveniences of bleaching by means of peroxide; thus, ozone would seem worth considering for patients asking for in-office tooth whitening.
