How do you condense gutta-percha?
Use Ultrasonics to cut and condense gutta percha with excellent results. The most common technique to cut and condense Gutta-Percha requires the use of expensive heating instruments. These may cost thousands of dollars and have no use in other daily procedures.
What are the disadvantages of gutta-percha?
Gutta-percha can be plasticized with solvents such as chloroform, eucalyptol, and xylol. Disadvantages include shrinkage caused by evaporation, voids, the inability to control the obturating material, and irritation of periradicular tissues.
What is gutta-percha points?
The go-to endodontic obturation material for many years, gutta percha points are used to fill canals following shaping and cleaning during root canal treatments. Produced from the coagulated latex of trees native to Malaysia, gutta percha is a natural material that is heated and then compressed into the canal.
Does gutta-percha shrink?
Conclusions: Gutta-percha designed for thermoplastic application shrinks quickly and extensively upon cooling.
Which instrument is used to laterally condense the gutta-percha in each canal?
compactor
First, gutta-percha is laterally condensed in the apical half of the canal to provide apical control, and then a compactor is used to plasticise and condense the gutta-percha in the straight coronal half of the canal.
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.
Does gutta-percha dissolve?
At 5-minute immersion time interval, xylene displayed the best dissolving efficacy in dissolving gutta-percha followed by refined orange oil and tetrachloroethylene in descending order. At 5-minute immersion time interval, all of the test solvents exhibited the same dissolving capacity in dissolving resilon.
What solvent can be used to remove gutta-percha?
In clinical practice chloroform is the most effective and most widely used solvent for gutta-percha. Other solvents include refined orange oil, halothane, tetrachloroethylene and xylene.
Does gutta-percha expire?
Do not use after the expiration date • Closely follow the recommended storage conditions. Failure to do so will cause the Gutta Percha to prematurely harden resulting in procedural delays or requiring re-treatment to remove the Gutta Percha.
What is tug back?
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].
What is used to dissolve gutta-percha?
Does chloroform dissolve gutta-percha?
Gutta-percha is soluble in a variety of organic solvents such as chloroform, halothane and rectified turpentine. Chloroform is the most effective solvent for gutta-percha (Tamse et al.
