Abstract
A gutta-percha composition for filling a tooth root canal includes a temperature indicating component, such that the user has a visual indication that the material is ready for placement in the prepared canal. The material may include a thermochromatic dye, bismuth oxide or the like, in an otherwise conventional obturation material.
Claims6
A composition for filling a tooth root canal comprising:
- a gutta-percha component;
- a first temperature indicating component;
- and
- a second temperature indicating component;
- wherein said first and said second temperature indicating components provide temperature indication at at least two different temperature ranges from each other;
- and
- wherein said first temperature indicating component changes color when it reaches a temperature of from about 40 to about 50 degrees C., and said second temperature indicating component changes color when it reaches a temperature of from about 60 to about 70 degrees C.
