Leaving an empty post space in a restored tooth can lead to infection and radiolucency. Prompt treatment of the post space resolves symptoms and promotes healing, highlighting the importance of proper endodontic procedures.

Area of Science:

  • Endodontics
  • Restorative Dentistry
  • Oral Radiology

Background:

  • Root canal treatment is a common dental procedure.
  • Post-and-core restorations are frequently used to support extensively damaged teeth.
  • Maintaining the integrity of the root canal system is crucial for long-term tooth survival.

Observation:

  • A case report details a mandibular left first molar that underwent root canal treatment.
  • The post space was prepared but intentionally left unfilled during coronal restoration.
  • The patient later presented with pain and a furcal radiolucency.

Findings:

  • The development of a periradicular radiolucency adjacent to an unfilled post space occurred.
  • Treatment involved cleaning, shaping, medicating, and filling the post space.

  • This intervention led to the resolution of clinical symptoms and radiographic healing of the radiolucency.

    • Implications:

    • Unfilled post spaces pose a risk of bacterial contamination and subsequent periradicular pathology.
    • Aseptic techniques are paramount during post space preparation.
    • Leaving a post space empty in a restored tooth is contraindicated and can compromise treatment outcomes.
