What is thermomechanical compaction?
Thermomechanical compaction is a simple and fast obturation procedure. 3. Thermomechanical compaction ends in a very homogenous root filling preventing the formation of voids.
What is McSpadden technique?
McSpadden Thermomechanical Compaction: With techniques that require heating techniques, the McSpadden technique uses instrument rotations of higher speeds to create controlled thermomechanical compaction for the gutta-percha and remove the problem of uncontrollable heat temperature.
What is Thermoplasticized gutta-percha?
Abstract. Gutta percha is the most widely used material in root canal obturation because of its relative inertness, lack of toxicity and biocompatibility. The most common method of obturation using gutta percha is lateral condensation, which has several disadvantages.
What is lateral condensation?
Lateral condensation technique is one of the most common methods of root canal obturation. In conventional obturation methods, the tug-back in the gutta-percha master cone is recommended in order to create and maintain the apical seal.
What is Tagger’s hybrid technique?
Other technique is Tagger’s Hybrid, in which the gutta-percha is thermoplasticized and compacted into root canal through motor-driven compactors.
What is the use of gutta-percha?
Gutta-percha is a material used to fill a tooth after a root canal procedure. Gutta-percha, a plastic substance from a Malaysian tree called a percha tree, is used as a permanent filling in root canals.
How do you use Thermafil?
Select a Thermafil obturator the same size as the “best fitting” verifier previously selected. Disinfect the obturator in 5. 5% sodium hypochlorite solution for one minute. Rinse it in 70% alcohol, then leave to air dry for several seconds to allow evaporation of excess alcohol.
How do you do lateral compaction?
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 gutta-percha cones?
Abstract. in English, Portuguese. The gutta-percha cones used in endodontic treatment are produced in aseptic conditions and their composition includes zinc oxide, which is responsible for antibacterial activity.
What is tug back in endodontics?
Tug-back is defined as a slight frictional resistance of a master point to withdrawal, which indicates a relative degree of adaptation at least in 2 dimensions, according to the American Association of Endodontists [6].
