Dentsply AH 26 is an epoxy-resin-based root canal
sealer widely used in endodontic dentistry. It is designed for the permanent
obturation (sealing) of root canals, typically used in combination with
gutta-percha points to ensure a fluid-tight seal.
Properties
It adapts closely
to the root canal walls, minimizing microleakage and preventing bacterial
re-entry.
AH 26 exhibits
very low volumetric shrinkage during polymerisation and has extremely low
solubility in tissue fluids.
It is highly
visible on X-rays (radiopaque), allowing dentists to clearly evaluate the
quality and depth of the root canal filling.
It is eugenol-free
and acrylic-free. It has historically been available in a
silver-containing version and a silver-free version. The silver-free
version is preferred to avoid the risk of tooth discoloration.
Complete removal
by rinsing thanks to its completely water-soluble formulation.
