This retired civil engeneer from the former island of Wieringen 77 years of age requested his premolar 24 to be repaired. The element was still slightly bleeding on preparing with HealOzone. Nevertheless the Glass Carbomer repair was proceeded. Two capsules were applied. Polishing was limited for now to let the Shark teeth filling material adhere properly enough in time. The procedure was non-invasive with no drilling, self adhesive with no etching. Solo with no assistant. The prognosis is fair. In any case some defect should be easily resolved with GCP. The risk of reaction is nill. HealOzone wih Glass Carbomer makes an excellent combination in my experience.
