This electrical engineer industrial production from Breda, 60 years of age came in with a cavity buccal of the molar 4.7 Previously this molar had been restored with lots of composite which now had partially broken off exposing the dentine. A Glass Carbomer filling was placed in bulk, self adhesive, after preparing with 30s HealOzone and some pH balancer drops. No drilling. This colour A2 will set in a few weeks. The GCP filling material consists of glass particles about ten micron in diameter, is mixed for 15s and is unique in its self healing property through ion exchange and biofusion with natural dentine. The prognosis for this filling is excellent. The remainder of the tooth may need some care in time to come. Contact details for professionals available on request.
