AH Plus is an example of which type of endodontic sealer?

• A. Epoxy resin–based sealer
• B. Zinc oxide eugenol–based sealer
• C. Bioceramic sealer
• D. Glass ionomer sealer

Answer: (A)

AH Plus is an epoxy resin–based endodontic sealer. Epoxy resin sealers use an epoxy polymer that cures to form a rigid, highly dimensional-stable network, which provides a tight seal against leakage and excellent seal durability along the canal walls and gutta-percha. This chemistry gives favored sealing ability, low solubility, and reliable long-term stability, along with good handling characteristics. This differs from zinc oxide eugenol–based sealers, which rely on a zinc oxide with eugenol matrix and tend to have different solubility and bonding behavior. It also isn’t a bioceramic sealer, which is typically calcium silicate–based and sets hydraulically in moisture, nor a glass ionomer sealer, which uses a polyacrylate/glass ionomer chemistry.
