Why it matters for dental

Endodontists and general dentists performing root-canal therapy can use the upcoming micro-CT data to decide which NiTi system best preserves dentin and respects canal anatomy in high-curvature molars, directly affecting long-term tooth retention and retreatment risk.

Key points

  • Publication slated for August 2026 in JOE (Vol 52, Issue 8) by Bago et al.; first peer-reviewed 3-D comparison of ProTaper Ultimate, TruNatomy, and WaveOne Gold in canals >30° curvature.
  • Micro-CT metrics will quantify canal transportation, centering ability, and dentin removal—variables that correlate with fracture resistance and future restorability.
  • Data will be clinically actionable for owners and specialists choosing a single-file vs multi-file strategy under microscope or CBCT guidance.
  • No regulatory or payer impact; strictly a clinical technique reference for endodontic cases.
