Vertical root fractures can occur in teeth without prior endodontic treatment or post placement. This study observed these fractures in severely worn molars, primarily in male patients.

Area of Science:

  • Dentistry
  • Endodontics
  • Oral Surgery

Background:

  • Vertical root fractures (VRFs) are commonly associated with endodontically treated teeth, often linked to post placement or condensation forces.
  • Previous literature predominantly attributes VRFs to iatrogenic causes during endodontic procedures.

Observation:

  • This study investigated 12 molars in 11 Chinese patients presenting with vertical root fractures.
  • Notably, these fractures occurred in teeth without any history of endodontic treatment or post placement.
  • The fractured teeth exhibited characteristics consistent with true vertical root fractures, confirmed post-extraction.

Findings:

  • A distinct pattern emerged: the majority of affected teeth were severely attrited mandibular molars in male patients.
  • All fractured teeth possessed clinically intact crowns with minimal or no restorative work.

  • This suggests a potential non-iatrogenic etiology for vertical root fractures in specific dental contexts.

    • Implications:

    • The findings challenge the conventional understanding of vertical root fracture etiology, highlighting cases unrelated to endodontic procedures.
    • This necessitates a re-evaluation of diagnostic approaches and treatment considerations for vertical root fractures, particularly in cases with intact crowns.
    • Further research is warranted to elucidate the specific biomechanical or etiological factors contributing to these non-iatrogenic vertical root fractures.
