- 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 which combine with the anionic molecules on the surface of the cell walls of the bacteria causing osmosis to malfunction.
- (Petereit & Kirch, W., 1998). 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 (Arends & David, 1998).
- 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 .
- Duration: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 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.
- Activ point for temporary root canal filling and prevention of reinfection.
- The ISO shaped points have a guttapercha matrix with 5% chlorhexidine diacetate 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.
