Summary
This summary is machine-generated.

The GentleWave System (GWS) and standard endodontic treatment showed no significant difference in postoperative pain incidence or intensity. Both methods resulted in a significant decrease in pain over time following the procedure.

Area of Science:

  • Endodontics
  • Dental Technology
  • Pain Management

Background:

  • Root canal cleaning and shaping are crucial for effective irrigant delivery.
  • Conventional endodontic irrigation uses needles and sonic activation.
  • The GentleWave System (GWS) integrates irrigant delivery with multisonic activation.

Purpose of the Study:

  • To compare the incidence and intensity of postoperative pain between the GentleWave System and standard endodontic treatment.
  • To evaluate the efficacy of GWS in reducing endodontic pain.

Main Methods:

  • A randomized clinical trial was conducted with two groups: standard treatment and GWS.
  • Patients recorded pain levels using a numeric rating scale at baseline and 6, 24, 72, and 168 hours post-treatment.
  • Blinding of participants to their assigned treatment group was maintained.

Main Results:

  • Postoperative pain occurred in 72.2% of the standard group and 83.3% of the GWS group.
  • Peak pain intensity was observed at 6 hours post-treatment for both groups.
  • A statistically significant decrease in pain over time was noted in both treatment groups (P < 1.237e-7).

Conclusions:

  • No significant difference in postoperative pain incidence or intensity was found between GWS and standard endodontic treatment.
  • Both treatment modalities demonstrated a significant reduction in pain over the observation period.
  • Further research may explore long-term pain outcomes and patient-reported satisfaction.
