For temporary root canal filling and prevention of reinfection. The points have a guttapercha matrix with 5% chlorhexidine diacetate. Chlorhexidine is known to be highly effective against bacteria and many other organisms including yeasts and fungi even in low concentrations.
- Provides a means for applying chlorhexidine directly into the root canal
- Easy to apply and easy to remove
FEATURES & ADVANTAGES
- Activ point for temporary root canal filling and prevention of reinfection.
- The ISO shaped points have a guttapercha matrix with 5% chlorhexidinediacetate and are radiopaque.
- Chlorhexidine has been used effectively in dentistry for many years and is known to be highly effective against bacteria and many organisms, including yeasts and fungi, even in low concentrations.
- Roeko’s innovation, activ point, provides a means for applying chlorhexidine directly into the root canal.
- For temporary filling of root canals
- For emergency root canal treatment
- The activ point is ready to use. It is firm for easy introduction into the root canal yet flexible to follow the curves of the canal.
- When chlorhexidine comes into contact with moisture it releases cations that combine with the anionic molecules on the surface of the cell walls of the bacteria causing osmosis to malfunction. Chlorhexidine is more soluble than calcium hydroxide for example.
- Due to electrostatic bonding and interactions the cations adhere to the dentine, to the enamel, and within the oral cavity. Activ point has been specially developed for the conditions in the root canal.
- The canal is so small that there is not even room for a drop of water.
- The majority of the space is taken up by the activ point, so the relationship of CHX to moisture allows a minimal inhibition concentration
DIRECTIONS TO USE
- Point containing chlorhexidine can be introduced quickly and easily into the canal and removed without any residue
- As always, the canal should be sufficiently cleaned and rinsed
- An activ point corresponding to the last used root canal instrument, or one size smaller, should be marked with the predetermined length and applied into the canal without condensation
- A drop of moisture (e.g. sterile H2O) may be used together with the activ point to accelerate the release of CHX.
- Further dissociation will be initiated by moisture flowing into the canal through the dentine tubules and apex.
- If the canal is not exactly round more points may be used to ensure sufficient surface contact for the moisture. It is recommended to fold the excess length into the opening of the canal if there is sufficient space. This facilitates removal
- The opening should be temporarily sealed with standard materials.
- 1 – 3 weeks
- The point should then be changed or the canal permanently filled in the usual manner. In certain clinical situations the point should be replaced at shorter intervals (after 2 – 3 days)
Removal of activ point
- The stability of the activ point is not affected by the release of chlorhexidine in moisture.
- It can easily be removed with tweezers or a probe even after 3 weeks. No residue is left in the canal.
