gutta-percha

 [gut″ah-per´chah]
the coagulated, dried, purified latex of trees of the genera Palaguium and Payena, most commonly Palaguium gutta; used in orthopedics for fracture splints, in surgery for temporary sealing of cavities, and in dentistry in the form of cones for filling root canals or sticks for sealing cavities over treatment.

gut·ta-per·cha

(gut'ă-pĕr'chă),
The coagulated, purified, dried, milky juice of trees of the genera Palaquium (especially P. gutta and Payena (family Sapotaceae); a polyterpene-containing a trans isomer of rubber used as a filling material in dentistry, and in the manufacture of splints and electrical insulators; a solution is used as a substitute for collodion, as a protective, and to seal incised wounds. Compare: chicle, gutta.

gutta-percha

/gut·ta-per·cha/ (gut″ah-pur´chah) the coagulated latex of a number of trees of the family Sapotaceae; used as a dental cement and in splints.

gutta-percha

[gut′ə pur′chə]
Etymology: Malay, getah-percha, latex sap
the coagulated rubbery sap of various tropical trees, used for temporarily sealing the dressings of prepared tooth cavities. When combined with fillers and coloring materials, it may be rolled into sheets and used to make temporary bases for dentures.

gut·ta-per·cha

(gut'ă-pĕr'chă)
The coagulated, purified, dried, milky juice of trees of the genera Palaguium and Payena (family Sapotaceae); used as a filling material in dentistry, especially to fill root canals in endodontics, and in the manufacture of splints and electrical insulators; a solution is used as a substitute for collodion, as a protective, and to seal incised wounds. Solid at room temperature and soft and pliable when heated.

gutta-percha (gut´ə-pur´chə),

n the coagulated juice of various tropical trees that has certain rubberlike properties. Used for temporary sealing of dressings in cavities; also used in the form of cones for filling root canals and in the form of sticks for sealing cavities over treatment.

However, Namazikhah et al (22) concluded that, if the guttapercha wasn't intentionally contaminated, there is no need for decontamination prior to root canal filling.
7, 9-10, 27) Some guttapercha disinfection protocols can be performed, such as cone immersion in 5,25% NaOCl for 1 minute, (6) use of 2.
In the present study, we could observe contamination in 30% (14/30) of the boxes of evaluated guttapercha cones, already in clinical use.
The microbial contamination observed in the present tests finds support among many studies, which also yielded the need for decontamination of gutta-percha immediately preceding the filling of root canals, especially studies investigating the presence of microbial contamination of guttapercha in unopened packages, (9, 23, 30, 32) and other studies evaluating this contamination in packages already in clinical use.
Presence of infection in form of periapical radiolucency and inadequate obturation of both the central incisors raised the need for the removal of old guttapercha followed by canal disinfection.
After cession, it took very little time for Iban to become aware of the opportunities that existed there for collecting guttapercha and other forest produce: as early as January 1883 Iban collectors had arrived in the area and this in turn attracted Chinese traders.
In 1891 came reports that problems were expected between Balait people and Iban living in the Baram over the collection of guttapercha, necessitating Hose to call the Iban back to Claudetown before problems arose (SG 1 Oct 1891:154; 2 Nov: 166).
In June 1891, Hose reported that the great Kenyan penghulu, Taman Bulan who had been instrumental in bringing both hostilities and peace to the Baram had expressed a desire to see Kuching, and this he had done with a passage on the Adeh, which had taken with it a full cargo of guttapercha and rattans (SG 1 Aug 1891:125).
Dentinal wall adaptation of thermoplasticized guttapercha in absence or presence of smear layer-a scanning electron microscopic study.
Root canal treatment of these teeth requires a root end closure technique to form a complete calcific barrier at the apex of the tooth against which a guttapercha filling can be condensed without the possibility of sealant or guttapercha going through the apex into the periapical tissues.
In the above case reports, the protocol for apexification with MTA was followed and obturation was done with thermoplasticized guttapercha as it does not cause excessive compaction forces on the thin dentinal walls of an immature tooth.
16) Thermoplasticized gutta-percha technique was followed for obturation as studies have shown that this technique leads to better flow of the guttapercha and sealer into the complex anatomy of the canal and gives a three-dimensional obturation of the root canal.
