Endodontic cement used as an intracanal filling material.
The powder and liquid form a viscous mixture, which is used with gutta-percha cones.
The setting of this cement is a reaction between Zinc Oxide and Eugenol, which in the presence of water form zinc eugenolate. The resin improves mixing characteristics and delays setting time. Radiopacity is enhanced by Bismuth and Barium salts.
The PULP FILL formulation is similar to that developed by GROSSMAN. This cement was developed seeking to satisfy the requirements established by GROSSMAN for a perfect endodontic filling cement, which are:
(1) adhesiveness – it must be tacky, when mixed, to provide a good adhesion between the cone and the canal;
(2) perfect closure – must provide an airtight seal;
(3) radiopaque – must be radiopaque so that it can be visualized by radiography;
(4) small particles – the powder particles must be very small so that they can easily mix with the liquid;
(5) not contracting – not contracting after placement;
(6) it must not stain the tooth structure;
(7) antibacterial action – it must be bacteriostatic or, at least, unsuitable for bacterial growth;
(8) it should harden slowly;
(9) insoluble – must be insoluble in tissue fluids;
(10) biocompatible – must be tolerated by tissues, ie, non-irritating to periapical tissues and
(11) removable – must be soluble in common solvent, in case it is necessary to remove the filling of the canal.
