This study found that dental impression materials, including Impregum and Jeltrate, exhibit cytotoxicity. Components of these materials also showed toxic effects, confirming potential adverse reactions in patients and dental practitioners.

Area of Science:

  • Biomaterials Science
  • Dental Materials Research
  • Toxicology

Background:

  • Dental impression materials are crucial for prosthodontic restorations.
  • Concerns exist regarding the biocompatibility of various dental impression materials.
  • Previous studies suggest potential adverse effects from certain impression materials.

Purpose of the Study:

  • To evaluate the cytotoxicity of commonly used dental impression materials.
  • To assess the cytotoxic potential of individual components within these materials.
  • To correlate in vitro findings with reported in vivo adverse effects.

Main Methods:

  • Tested six dental impression material brands: Impregum, Reprosil, Surgident, Permlastic, Jeltrate Regular, and Jeltrate Fast Set.
  • Utilized three distinct in vitro assay methods to determine cytotoxic effects.

  • Analyzed both the final impression materials and their constituent components.

    • Main Results:

    • All tested impression materials demonstrated cytotoxicity across all three assay methods.
    • Several individual components within the impression materials were also found to be cytotoxic.
    • The degree of cytotoxicity varied among the different materials and components.

    Conclusions:

    • The findings confirm the cytotoxic potential of the evaluated dental impression materials.
    • These results align with existing literature on adverse in vivo effects observed in patients and dental professionals.
    • Further research into safer material formulations is warranted to mitigate patient and practitioner risks.
