This lady research Publisher 59 years of age from the province of Drenthe came in with a loose partially broken off amalgam filling. With a diamond drill the old amalgam was split in two and easily removed. A wide cup 8mm diameter 20mm long was applied on the molar 4.7 tooth for 60s with Ozone from HealOzone X4 Next Generation. A Garrison FX175 matrix shield with a wedge type WDYL Extra Small held in place with a holding ring type Wide Prep FX600 was used for the Glass Carbomer mixture colour A2 placement. Light cured for 5 times 30s and chemically hardened for 5 more minutes. Access removal and modeling as finish. A life expectancy was humbly requested of fourty years. With the self curing properties of these “shark teeth” glass particles held together with carboxyl groups and polymers special ion formula this is not outrageous but realistic. However if anything might happen these type of fillings can easily be repaired. No reactions, after pain or secondary cariës is to be expected at all. A small piece of amalgam adhered still solidly and was left in place.
