Gutta-percha
Pronunciation: gut-uh-PUR-chuh
A natural thermoplastic material derived from the Palaquium tree, used as the primary core material for root canal obturation.
Full Definition
Gutta-percha is a rigid natural polymer obtained from the latex of tropical trees of the genus Palaquium. In dentistry, it is manufactured into standardized points (cones) that are used to fill and seal the root canal space following endodontic treatment, typically in conjunction with an endodontic sealer. Its widespread use stems from its biocompatibility, dimensional stability, radiopacity, and the ability to be softened by heat for thermoplastic techniques. Editors must retain the hyphen ('gutta-percha') and note that it is lowercase except when starting a sentence. It should not be confused with 'guttapercha' (one word — occasionally seen in older texts) or with bioceramic and polymer-based alternative filling materials.
Usage
Usage note: Always hyphenated: 'gutta-percha'. Lowercase unless sentence-initial. The informal abbreviation 'GP' is acceptable in clinical notes but should be expanded on first use in formal publications.
In Context
- "The root canals were obturated with size 25 gutta-percha points and a calcium silicate–based sealer." — Endodontic treatment record
- "Warm vertical compaction of gutta-percha allows the material to flow into complex root canal anatomy, improving the three-dimensional seal." — Endodontic textbook chapter
