Summary

Endodontic reintervention with manual or reciprocating instruments showed no difference in postoperative pain or analgesic use. However, reciprocating systems significantly reduced working time for root canal filling removal and re-instrumentation.

Area of Science:

  • Endodontics
  • Dental Materials Science
  • Pain Management

Background:

  • Endodontic reintervention is crucial for treating persistent apical periodontitis.
  • Choosing the right instrumentation technique impacts patient outcomes and procedural efficiency.

Purpose of the Study:

  • To compare postoperative pain and analgesic intake between manual and engine-driven reciprocating instruments during endodontic reintervention.
  • To evaluate the working time for root canal filling removal and re-instrumentation.

Main Methods:

  • A randomized clinical trial included 48 patients with asymptomatic apical periodontitis.
  • Participants were assigned to manual stainless steel or nickel-titanium reciprocating instruments (Reciproc).
  • Postoperative pain (Numerical Rating Scale) and analgesic intake were assessed at multiple time points.

Main Results:

  • No significant differences in pain prevalence, intensity, or analgesic intake were observed between the groups.
  • Working time for root canal filling removal and re-instrumentation was significantly shorter with reciprocating instruments (18 vs. 41 minutes).

Conclusions:

  • Both manual and reciprocating instruments yield comparable results for postoperative pain and analgesic needs in endodontic reintervention.
  • Reciprocating systems offer a substantial time-saving advantage for root canal procedures.
