Why it matters for dental
Endodontists and general dentists performing root canals must weigh instrumentation choices that affect long-term tooth survival and the need for costly retreatment or crowns.
Key points
- Researchers tested four file systems on 40 mandibular premolars and recorded pericervical dentin loss after each sequence.
- Rotary files with a 6% taper removed 0.42 mm of pericervical dentin, the largest loss among the groups tested.
- Teeth prepared with files up to F2 showed the highest fracture resistance at 724.91 Newtons.
- The investigators concluded that file type alone may not determine pericervical dentin loss or fracture risk.
