Summary

New temporary restorative resins using non-phthalate plasticizers like TEC, TBC, and DBS show mechanical properties comparable to commercial options. Appropriate resin monomer and plasticizer proportions are key for developing effective temporary dental materials.

Area of Science:

  • Dental Materials Science
  • Polymer Chemistry

Background:

  • Temporary restorative resins are crucial in dental procedures.
  • Traditional resins often use phthalate ester plasticizers, raising potential health concerns.
  • Developing safer alternatives is an ongoing research objective.

Purpose of the Study:

  • To evaluate temporary restorative resins formulated with non-phthalate ester plasticizers.
  • To compare the mechanical properties of these experimental resins against phthalate-based and commercial products.

Main Methods:

  • Tested tri-ethyl citrate (TEC), tri-butyl citrate (TBC), and di-butyl sebacate (DBS) as non-phthalate plasticizers.
  • Varied plasticizer to PMMA/MMA resin ratios from 30-60% (wt).
  • Assessed mechanical properties via diametral compressive strength and resistance to explorer insertion.

Main Results:

  • Experimental resins with 40-50% TEC, TBC, DBP or 30-40% DBS exhibited strengths equivalent to commercial temporary restorative resins.
  • Similar performance was observed for resistance to explorer insertion across tested formulations.

Conclusions:

  • Temporary restorative resins can be successfully formulated using non-phthalate ester plasticizers.
  • Optimizing the ratio of resin monomer to non-phthalate plasticizer is essential for achieving desired mechanical properties.
