| Summary: | Background
Correct obturation of the root canal system is essential for the success of endodontic treatment, which is achieved by means of a core and cement. There are several root canal cements (RCCs) on the market; however, because of their excellent characteristics, epoxy resin-based sealers (ERBSs) have been widely used.
Objective
The main aim of this review is to analyze and integrate the available information on the different ERBSs.
Methods
An electronic search was performed in the PubMed and Scopus databases, using as search terms “epoxy resin” AND “root canal treatment”, “epoxy resin” AND “endodontics”.
Results
In general, the ERBSs have good flow properties, film thickness, solubility, dimensional stability, sealing capacity, and radiopacity; they are also able to adhere to dentin while exhibiting low toxicity and some antibacterial effects. However, their main disadvantage is their lack of bioactivity and biomineralization capability.
Conclusion
A large number of ERBSs were found to be available on the market and AH Plus keeps being the gold standard RCC. However, information on many of them is limited or non-existent, which could be due to the fact that some of them are relatively new. The latter emphasizes the need for relevant research on the physicochemical and biological properties of some ERBSs, with the aim of supporting their clinical use with sufficient evidence via prospective and long-term studies.
