Postoperative pain after single-visit root canal treatment (RCT) was compared using three rotary file systems. TruNatomy resulted in significantly less pain than GenEndo and Jizai, indicating its potential for improved patient comfort.

Area of Science:

  • Endodontics
  • Dental Materials Science

Background:

  • Postoperative pain is a common concern after single-visit root canal treatment (RCT).
  • Factors influencing pain include instrumentation technique and apical debris extrusion.
  • Minimizing patient discomfort is a key goal in endodontic therapy.

Purpose of the Study:

  • To compare postoperative discomfort following single-visit RCT using three distinct rotary file systems: TruNatomy, GenEndo, and Jizai.
  • To evaluate the efficacy of different instrumentation systems in managing endodontic pain.

Main Methods:

  • A prospective clinical observational study involving 135 patients with asymptomatic irreversible pulpitis in posterior mandibular teeth.
  • Patients were treated with one of three rotary systems (TruNatomy, GenEndo, Jizai; n=45 each) under standardized conditions.

  • Postoperative pain was assessed using a visual analog scale (VAS) at 24h, 48h, 72h, and 7 days.

    • Main Results:

    • All rotary systems showed a statistically significant reduction in VAS scores over time (p < 0.001).
    • The TruNatomy group exhibited the lowest mean pain scores throughout the study period.
    • Significantly lower pain scores were observed in the TruNatomy group compared to GenEndo and Jizai at all time points (p = 0.001).

    Conclusions:

    • All tested rotary systems effectively reduced postoperative pain over time.
    • The TruNatomy system was associated with significantly lower postoperative pain compared to GenEndo and Jizai.
    • The flexible and minimally invasive design of TruNatomy may contribute to reduced periapical irritation and enhanced patient comfort.
