Retrograde fillings are recommended during apical surgery to seal infected root canals, enhancing prognosis. Amalgam with cavity varnish is the preferred material, but complete root canal treatment is superior if feasible.

Area of Science:

  • Endodontics
  • Oral Surgery

Background:

  • Retrograde fillings seal infected root canals during apical surgery.
  • Debate exists regarding routine use and material choice for retrograde fillings.

Purpose of the Study:

  • To review the literature on retrograde filling materials and techniques in apical surgery.
  • To determine the optimal material and indications for retrograde fillings.

Main Methods:

  • Literature review of studies from the past decade.
  • Emphasis on clinical comparisons over in vitro sealability studies.
  • Consideration of in vivo animal studies to mitigate clinical study challenges.

Main Results:

  • Retrograde fillings should be routine in apical surgery unless orthograde endodontic treatment is performed concurrently.

  • Amalgam used with cavity varnish is identified as the material of choice.
  • Retrograde filling is not a substitute for complete root canal debridement and obturation.

    • Conclusions:

    • Retrograde fillings improve the prognosis of apical surgery when orthograde treatment is not feasible.
    • Amalgam with cavity varnish is the recommended material for retrograde fillings.
    • Complete retrograde endodontic treatment is preferable to a simple retrograde filling if technically possible.
