The most commonly used core material for root canal filling is gutta-percha and as the gutta-percha by itself cannot obturate the complete root canal system, owing to its poor sealing properties hence, a sealer is used in combination with root filling material. Sealer is more important than the core obturating material. Sealer plays a secondary role by merely reinforcing (binding or luting) the gutta-percha to the canal walls, however, it is now confirmed that the sealer has a prime role in sealing the canal by blocking the irregularities between the canal space and the core filling material.
