Hygenic??Calcium Hydroxide Points

HYGENIC Calcium Hydroxide Points are time release preparations, which release calcium hydroxide from a guttapercha matrix.

Composition:

• 52 % calcium hydroxide
• 42 % guttapercha
• Sodium chloride
• Surfactant and colouring agents.

Indications for use:

• For temporary filling of root canal with calcium hydroxide before permanent treatment is preformed
• For emergency root canal treatment
• For treatment of root resorption
• Vital enucleation
• In Apexification

Properties:

The point is ready for use, firm yet flexible for easy introduction into the root canal. Pure calcium hydroxide is homogeneously distributed throughout a guttapercha matrix. Sodium chloride and the surfactant improve the solubility of calcium hydroxide and the mobility of the ions. The points are ISO standard and light brown to prevent confusion with guttapercha points.

Release of hydroxide ions:

A drop of sterile water may be used together with the point for the initial release of ions. However, after inserting the point into the canal, sufficient fluid flows into the space between the point and the canal wall from the dentine tubules and apical area to activate the Ca(OH)2 even without additional water. The moisture is sufficient to cause dissociation of the ions from the point, so that an alkaline environment develops within the canal and the pH quickly rises above 12. The concentration of the Ca(OH)2 in the point ensures that sufficient Ca(OH)2 is always present in the canal.
