Two HealOzone X4 next generation instrument sets have arrived. Features have improved of the earlier edition of year 2003. Added safety measures, enhanced ozone concentration and longer menu application from 40s to 60s maximum. These HealOzone X4’s should reliably serve in years to come. The demand on the instruments is relatively high as HealOzone is practiced stand alone here more or less continuous. Bodily dental tissue, dentine, enamel, including dental roots are being cured in a few sessions. When necessary maintance care is done, varying from maybe once in six months or a few years. Fillings are placed without drilling as you can see in our study cases. It makes our protocol unique. While it should become standard procedure in my experience. Insurance does not cover HealOzone in this country. We are trying to get in touch with the Minister and the 13 political parties of parliament as well as the NZa Nederlandse Zorgautoriteit.
