Jak wypełniać pod ciśnieniem
During this process, an endodontic aspirator tip was used to dry the root canals. The Swiss dental specialist COLTENE recently introduced an aspirating tip specially developed for drying root canals. With an outer diameter corresponding to ISO 60, the Surgitip-endo can be inserted directly into the prepared canal where it removes rinsing solutions and other moisture quickly and effectively at the same time. Thanks to a special fully rotating ball joint, the suction tip is highly flexible and collapsing of the tip is therefore avoided (Figure 4). You can easily fit it into root canals that are normally hard to reach without having to bend the canal tip. After drying the confluent canals, the Surgitip-endo was fitted to the buccal canal orifice and the irrigation solution was injected in the lingual canal. Simultaneous negative and positive pressure irrigation from different orifices created a continuous current of fresh irrigant washing out all debris.
In the next step the preparation for negative pressure filling of the root canal system was taking place. This special filling system was created with the use of the Surgitip-endo and the tight seal material GuttaFlow 2 (Figure 5).
This filling material combines cold free-flow gutta-percha and a sealer creating an easy to handle, fast flowing filling material, which has been proven as a reliable barrier against bacteria and liquids re-entering the root canal. Its working time takes approximately ten to fifteen minutes. [...]
