Gutta-Percha Root Canal Filling : Use and Procedure Endodontic treatment normally entails a root canal. Gutta-percha is the standard filling material. Gutta percha is the material used to fill the tooth.
It is a thermoplastic filling material that is heated and compressed into the canal(s) of the tooth which is then sealed with an adhesive cement. Vertical condensation of warm gutta-percha involves applying heat to the gutta-percha , condensing it down the root canal from coronal to apical (the downpack) and then filling the remaining space (the backfill).
The procedure aims to seal the terminus of the canal with an accurate cone fit, and the downpack then forces sealer and gutta-percha along the lines of least resistance. Now we know that for optimum success the outer boundary of the gutta-percha fill should be the anatomic apex. There is only one instrument that will locate that anatomic landmark, and that is the newer apex locators. The newer apex locators (within the last years) are very accurate. Please read the instructions.
Bowman used GP cones as the sole material for root filling. Rickert recommended the use of SE with a GP cone.
Stephen Buchanan, Autofit gutta percha is the latest innovation in filling materials. Greater Taper cones are designed to match canals shaped with Greater Taper files. Autofit cones have a parallel shank that is tapered to a point (similar to the end of a pencil).
Root canal filling material ( gutta percha ) is placed in the canals and the tooth is sealed with a temporary filling to protect it from contamination. Then a crown is usually placed over the tooth to seal and protect it from recontamination and future damage. This “biofilm” allows undisturbed growth of the bacteria and renders them particularly resistant to the defences of the host,.
Gutta - percha refers both to trees of the genus Palaquium in the family Sapotaceae and the rigi naturally biologically inert, resilient, electrically nonconductive, thermoplastic latex produced from the sap of these trees, particularly from Palaquium gutta. The gutta percha is a plastic substance that comes from several Malaysian trees and is used as a permanent filling in root canals, according to Merriam-Webster.

The information in this MSDS is, to the best of our knowledge, believed to be accurate. The gutta - percha cones can be manipulated into the root canal with either cold lateral condensation, or through a method which involves softening the core filling material with the application of heat, which was introduced more than years ago by Dr. The gutta - percha and sealer filling material has been the most popular and most tested filling material throughout the history of nonsurgical endodontic procedures.
Root canal overfills occur when a dentist is obturating ( filling ) a root canal.
If the gutta percha extrudes out the end of the root it is called an overfill. Usually over fills are not a problem as long as the resulting apical seal that is created is good. Sometimes this is not the case, since the gutta percha may have slipped through because it was not of sufficient diameter to bind at the apex. Standard root canal therapy uses gutta percha , the coagulated sap of certain tropical trees. The mechanical properties were indicative of a partially crystalline viscoelastic polymeric material.
The standard filling material is gutta - percha , a natural polymer prepared from latex from the percha tree (Palaquium gutta ). The standard endodontic technique involves inserting a gutta - percha cone (a point) into the cleaned-out root canal along with a sealing cement. A rubber-like material called gutta percha is often used. Your dentist will close the opening in your tooth with a temporary filling , while you wait for the permanent crown.
After a few weeks, your dentist will finish the treatment by placing a permanent crown or a similar type of restoration on the top of the tooth.
