Description

Endodontic Cement.

PULP FILL is an endodontic cement used as an intracanal filling material.
The powder and liquid form a mixture of viscous consistency, 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 optimized by Bismuth and Barium salts.
The formulation of PULP FILL is similar to that developed by GROSSMAN. This cement was developed seeking to satisfy the requirements established by GROSSMAN for a perfect endodontic obturator cement, which are: (1) adhesiveness – it must be sticky, when mixed, to provide good adhesion between the cone and the root canal; (2) tight 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 mix easily with the liquid; (5) not shrink – must not shrink once placed; (6) must not stain tooth structure; (7) antibacterial action – must be bacteriostatic or at least unsuitable for bacterial growth; (8) must harden slowly; (9) insoluble – must be insoluble in tissue fluids; (10) biocompatible – must be tolerated by the tissues, ie, non-irritating to the periapical tissues and (11) removable – must be soluble in common solvent, in case it is necessary to remove the filling from the root canal.
