“Endodontic Sealers”: Current Concepts and Comparative Analysis.

The main aim of root canal therapy is the removal of microbial contaminants in conjunction with the total closure of the root canal system. Root canal sealers along with solid core
material plays a major role in achieving the three dimensional sealing of the root canal system.
These sealers are binding agents which are used to adapt the rigid gutta-percha to canal walls
and to fill up the voids, accessory canals and irregularities within the canal. Root canal sealers,
although used only as adjunctive materials in the obturation of root canals, have been shown
to influence the outcome of endodontic treatment. A perfect combination of sealing ability and
biocompatibility is what an ideal root canal sealer should possess. This article discusses the
current concepts in the usage of different sealers in endodontic therapy and their comparison in
order to draw some clinical inferences.

Root canal therapy depends on integrally related root canal treatment phases: microbial control, cleaning and shaping, and effective sealing of the root canal system. The success
of each depends on the execution of the final phase.

Endodontic filling materials may be consider, The most commonly used core material is Gutta-percha, which occupies bulk of the canal space while the root canal sealer fills the interface between the core material and the dentin wall, the voids inside the core material and the accessory canals and also serves as a lubricant, thus helping to obtain a fluid tight seal.
