Coltene Roeko Activ Point Chlorhexidine Points


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.


activ point consists of chlorhexidine diacetate (5%), guttapercha, ZnO, BaSO4, and colouring agents.


 for temporary filling of root canals

• for emergency root canal treatment


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 .


The ISO 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).

Tests on activ point:

Agar diffusion test: On condition that the substances being tested diffuse in agar, growth and inhibition of bacteria, fungi and yeasts can be tested. When activ point and various organisms are put onto an agar plate a clear inhibition area can be seen. The CHX which is released from the point obviously limits the growth of organisms in this test. The size of the inhibition area varies from organism to organism.
