  Gutta Percha - LoveToKnow 1911
Gutta percha trees often attain a height of 70 to loo ft. and the trunk has a diameter of from 2 to 3 ft. They are stated to be mature when about thirty years old.
Gutta percha appears in commerce in the form of blocks or cakes of a dirty greyish appearance, often exhibiting a reddish tinge, and just soft enough to be indented by the nail.
Gutta percha is not dissolved by most liquids, although some remove resinous constituents; the best solvents are oil of turpentine, coal-tar oil, carbon bisulphide and chloroform, and light petroleum when hot.

 History of the Atlantic Cable & Submarine Telegraphy - The Gutta Percha Company
Introduced to Britain in 1843, gutta percha is the gum of a tree native to the Malay Peninsula and Malaysia.
Gutta percha proved to be an ideal insulator for submarine cables, and as a further benefit for cable use it was found that gutta percha's insulating properties improved under the pressure and temperature conditions of the ocean bed.
Gutta percha proved to be such a well-suited material for insulating submarine cables that it was used almost exclusively until finally superseded by polythene in the early 1930s.

 Gutta Percha - A Natural Form of Rubber
Gutta Percha is a natural polymer, chemically the same as natural rubber, however, it has a different molecular shape, giving it different properties.
Gutta percha was first introduced to the west by William Mongomerie in 1843.
Gutta percha is rarely used today, although some dentists use it to make temporary fillings.

 Gutta Percha 2
Gutta percha was obtained from a variety of guttiferous trees throughout the Pacific Rim although different varieties produce materials of differing quality.
However, Gutta percha had properties which could be exploited and three of these, together with its softening at easily attainable temperatures, provided its three main areas of use until each was superseded by advances in synthetic plastic materials.
Gutta percha is very stable underwater and the cables lasted many years - it would not surprise me if some still existed today although modern ones are plastic insulated and coated.

 Should you expect any pain after root canal treatment?
Gutta percha comes in preformed cones that are sized to match the files which have been used to clean out the inside of the tooth.
Sometimes several cones of gutta percha need to be placed before the interior of the tooth has been filled adequately.
As an alternative to the use of preformed cones, sometimes a dentist will place the gutta percha via the use of a gutta percha "gun." This apparatus is somewhat similar to a hot glue gun.

The warm Gutta percha technique is based upon intimate three-dimensional adaptation of the filling material (and sealer) to the canal system.
To ensure better adaptation of the gutta percha cone, Chloroform is used in a 2-second dip technique.
The intimate adaptation of the Gutta percha to the canal walls means that caution must be used when applying sealer.

 Obtura
You control the viscosity and flow rate, so you control the technique.Softening gutta percha allows it to be easily condensed into places it would not otherwise go.
Unlike gutta percha dissolved in a solvent, there is no detectable shrinkage with the Obtura 11.
As the gutta percha is forced through the applicator needle, it expands slightly due to die swell, offsetting any thermal shrinkage and ensuring a perfect seal throughout the length of the canal.

 Frater - Spring 2005
Recently, Medicated Gutta Percha (MGP) containing iodoform (triiodomethane) have arrived on the market suggesting that it has an increased antimicrobial activity7 and may have a place in mainstream endodontic therapy.
The purpose of this study was to compare the abilities of MGP and standard gutta percha points in resisting infiltration of E.
One possible explanation for this is found in the patent for the Medicated Gutta Percha point which says that iodoform is leached from the gutta percha in the presence of saliva.

 Gutta Percha
The “Balata” gum is of a character somewhat between caoutchouc and gutta percha, combining in some degree the elasticity of the one with the ductility of the other, freely softening and becoming plastic and easily moulded like gutta percha.
When dissolved in ordinary gutta percha solvents, it, after the evaporation of the solvent, remains some times soft and viscid, and partakes somewhat of the character of bird-lime.
We have no doubt that many a parcel of what would otherwise be good gutta percha, is spoilt through not being well boiled immediately after collection from the tree.

 American Latex Allergy Association | Latex Allergy Topics
Gutta-percha and gutta-balata are derived from the Paliquium gutta and Mimusops globsa trees, respectively, that are in the same botanical family as the rubber tree Hevea brasilienisis.
The objective of this study was to investigate the potential cross-reactivity between gutta percha, gutta balata, and NRL.
However, this potential risk should be viewed as minimal since gutta balata is mixed with inert gutta percha and is not likely to be released from the tooth cavity.

 Fitting a Gutta Percha Point
In a single-point technique such as the EZ-Fill® obturation technique, we aim for filling 95 percent of the canal with gutta percha and the remaining 5 percent with the sealer (EZ-Fill epoxy cement).
When this happens, it means that the tip of the gutta percha point is sticking out the apex into the ligament and bony tissue, as shown in Figure 8.
Once you the fit the medium gutta percha point to its correct measurement you are guaranteed that when you take your final x-ray it will be exactly where you fitted it to in the canal.

Gutta-percha, created by boiling the sap of the Malayan gutta tree, was similar to rubber but lacked rubber's elasticity.
And the Gutta Percha Company, the main importer of the substance from Malaya, reaped the rewards.
Polyethylene would eventually replace gutta-percha in the insulation of underwater cables as well as most other uses, but the boiled sap of the gutta tree is still used by dentists to make temporary fillings.
