What is lateral compaction technique?
In this technique, the terminal 3 mm of gutta-percha master cone is placed in chloroform for 1 second and then compressed in to the canal. Then after 25 seconds it is emitted, covered with sealer and replaced into the root canal. Finally, the root canal is obturated using lateral condensation technique.
How do you Obtrate a root canal?
The obturation protocol for conventional root canal obturation includes irrigation with sodium hypochlorite to eliminate the microorganisms, followed by irrigation with a calcium chelator to remove the smear layer; thus, the seared can penetrate the dental tubules and enhance the bonding by producing resin tags.
What is the cold lateral condensation technique?
Place a D-11 spreader in the canal along side the cone. Apply pressure apically to push the spreader in as far as possible, and spread from side to side. This side-to-side or, lateral, spreading motion is the basis for the technique name, lateral condensation.
What is obturation of root canal?
Obturation is the technical term for a method of filling and sealing a tooth with root canal material.
What is master cone in endodontics?
Customized master cones represent a change in concept: rather than instrumenting the root canal to fit the shape of a round, industrial, master cone, a cone is prepared to fit the shape of the ready-to-fill canal.
What is the master apical file?
The MAF is the last file taken to the minor constriction (MC) of the apical foramen. Its diameter becomes the final prepared diameter of the canal at the MC.
What is obturation technique?
What material is used for the obturation of a canal?
Historically, gutta-percha, the trans-isomer of polyisoprene, has been the material of choice as a solid, inert core filling material for root canal obturation, beginning with Bowman’s introduction of the material into endodontics in 1867 .
