What is Carrier obturation?

Carrier-based obturation is the only filling technique that can simultaneously deliver and compact warm gutta-percha to the terminus of canals that have coronal or mid-root curvatures (Figure 10a). Once a canal has been dried, root canal sealer may be placed using the EndoActivator (EA) (Dentsply Sirona).

What is BMP in RCT?

What is BMP in Root Canal Treatment? Biomechanical preparation is the achievement of free access to the apical foramen via the root canal by mechanical means. It is directly related to subsequent disinfection and filling.

What is obturation technique?

Obturation is the technical term for a method of filling and sealing a tooth with root canal material.

What are the criteria for obturation?

The radiographic criteria for evaluating obturation include the following categories: length, taper, density, GP and sealer removal to the facial cementoenamel junction in anterior teeth and to the canal orifice in posterior teeth, and an adequate provisional or definitive restoration (Fig. 9.12).

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.

What is Chemomechanical preparation?

Chemomechanical preparation of the root canal includes both mechanical instrumentation and antibacterial irrigation, and is principally directed toward the elimination of micro-organisms from the root canal system.

Which is best obturation technique?

With respect to obturation, there are 3 techniques that are employed.

1. Warm Vertical Condensation. This is the most commonly used technique in North America.
2. Carrier-based techniques. This is a popular option used to fill canal spaces.
3. Lateral condensation.

What types of compaction we do while obturation?

Four basic techniques exist for the obtu- ration of the root canal system with gutta-percha and sealer (Figure 4): (1) the cold compaction of gutta-percha; (2) the compaction of heat-softened gutta-percha with cold instru- ments until it has cooled; (3) the compaction of gutta-percha that has been thermoplasticized.

When was the first carrier-based obturator invented?

The carrier-based obturation concept was initially described by Dr. W.B. Johnson in 1978. However, the first carrier-based obturator (Thermafil) with a metal carrier was only commercialized in 1991.

Is Thermafil a carrier-based obturation?

Thermafil can be thought of in that era as what we call today carrier-based obturation. When Thermafil came out, it was accepted by many dentists. It was rejected more or less uniformly by all endodontists because the stigma was we were leaving behind a polysulfone carrier inside a finished shaped and obturated canal.

Is carrier-based obturation the gold standard in endodontics?

He, and J. L. Schweiter, “Current use and views of carrier-based obturation: report of a survey,” American Association of Endodontists Annual Session, 2009. View at: Google Scholar ]. It has long been used as the gold standard in comparison to more newly developed techniques; however, many of these studies have been performed in vitro [ 7

What are the different types of obturators?

In the last 20 years, carrier-based obturation techniques have become very popular with the introduction of many different types of obturators including ProTaper® Obturators, ProTaper® Next™ Obturators, WaveOne® Gold Obturators, GT Obturators (all Dentsply Sirona) and so on (Figure 2).
