Summary

Resinifying therapy shows promise in root canal treatment, effectively combating microorganisms and penetrating dentinal tubules. While periapical tissue repair takes time, clinical function remains positive, indicating a viable therapeutic approach.

Area of Science:

  • Endodontics
  • Dental Materials Science
  • Histopathology

Background:

  • Root canal treatment aims to eliminate intraradicular infection and seal the root canal system.
  • Periapical inflammation and infection pose challenges in endodontic therapy.
  • Novel materials are continuously investigated for improved endodontic outcomes.

Purpose of the Study:

  • To histologically evaluate the periapical tissue response to resin resorcinol.
  • To assess the antibacterial efficacy of resin resorcinol against common oral microorganisms.
  • To determine the penetration depth of resin resorcinol into dentinal tubules.

Main Methods:

  • Histological examination of periapical tissues in rabbits and rats after 12 days.
  • Bacteriological analysis of resin resorcinol.

  • Microscopic evaluation of resin penetration in human teeth.

    • Main Results:

    • Significant presence of lymphocytes and macrophages, with granuloma formation, indicating prolonged resin presence.
    • Resin penetration observed up to three-fourths the length of dentinal tubules.
    • Resin resorcinol demonstrated effectiveness against eight common microorganisms.

    Conclusions:

    • Resinifying therapy exhibits antimicrobial properties and good dentinal tubule penetration.
    • Periapical tissue healing may require an extended period, but clinical tooth function is maintained.
    • Resinifying therapy presents an effective and economical option for root canal treatment.
