[Retrograde root canal filling using resin and a dentin bonding agent: operative procedures].
Using a specially designed filled resin and the bonding agent Gluma, the aims were to obtain a thin retrograde filling covering the slightly concave root surface which would close all root canals and avoid excess filling material. To achieve a strong bond, the resin must be applied to an absolutely dry Gluma surface, free of all traces of blood or saliva. Hemostasis was obtained primarily by applying 1% adrenalin and by use of a needle suction tip. Absence of moisture was obtained by removing all soft tissues from the cavity, using dry compressed air and avoiding condensed moisture from a cool resin. To avoid loosening of the filling, the working time of the resin must not be exceeded, and removal of excess filling material must not be done before polymerization is complete. Contamination of the various chemicals and filled resin must be avoided in order to avoid damage to the surrounding tissues.
