Hora est 4. Interacties tussen irrigatie-oplossingen, wortelkanaalcementen en dentine

In the field of endodontology, antibacterial activity of irrigants has been investigated many times. The influence of these solutions on the bonding of root canal sealers, however, has hardly been studied. The objective of this doctoral research was to determine the interactions between root canal sealers and root dentin, and to determine the influence of irrigants on these interactions. The various studies revealed that irrigants have an influence on the bonding of sealers based on epoxy resin, calcium hydroxide, silicones and calcium silicate. In the case of a sealer based on epoxy resin (AH Plus), the irrigation protocol had an influence on the bond strength (adhesion) on dentin, by means of which the seal was also improved. The results of this research produced better insights into the mechanisms at play in the adhesive properties of root canal sealers. Eventually, this might result in improved treatment outcomes of root canal treatments.
