ENDO 1 – Procedure Management, Records, And Clinical Cases Practice Test

In endodontics, a sealer’s job is to create a durable, stable, and biocompatible seal that resists dissolution and provides a good bond to dentin and gutta-percha. Among the common choices, epoxy resin–based sealers and calcium silicate–based (bioceramic) sealers are favored for their excellent sealing, low solubility, and long-term stability. Zinc oxide–eugenol–based sealers have a long history and can be useful, but they come with drawbacks like potential solubility and softer properties over time. Glass ionomer cement sealers, while available, are not routinely used as endodontic sealers today because they tend to have more moisture sensitivity during setting, higher long-term solubility, and less reliable sealing performance compared with the other options. Therefore, glass ionomer cement sealer is not a common endodontic sealer.
