Approximately 35-40% of the root canal surface remains unchanged after preparation with an instrument.
CanalBrush is a highly flexible endodontic brush made of polypropylene.
It is used during root canal treatments to remove dentin, plaque and other impurities loosened by files and drills.
The extremely small CanalBrush helps cleaning parts of the root canal which are not reached by files.
The use of CanalBrush in connection with an irrigating solution (e.g. NaOCl, NaCl, H2O2, alcohol, CHX) increases considerably the cleaning effect of irrigating solutions on the root canal surface.
CanalBrush can be used manually with a rotary action. However, it is more efficient to use it with a contra-angle handpiece at a maximum of 600 rpm.
Advantages:
better cleaning effect than with files, without enlarging the canal
very flexible, lower risk of breakage
can be autoclaved at 134°C before use
can be used to place post cements or adhesives
with endo stops for length control
This brush is not to be used for agitating a chelating agent in the root canal (according to US Patent no. 6,179,617).
