Evaluation of Postendodontic Pain Using Multiple and Single Rotary File Systems in Single-Visit Endodontics - A...

Area of Science:

• Endodontics
• Dental Materials Science

Background:

• Postendodontic pain is a common clinical concern following root canal therapy.
• The choice of rotary file system impacts postoperative discomfort.

Purpose of the Study:

• To compare postendodontic pain levels associated with single versus multiple rotary file systems in single-visit endodontics.
• To evaluate the influence of rotary instrumentation on patient-reported pain.

Main Methods:

• Sixty patients undergoing single-visit root canal treatment were randomized into two groups: multiple rotary files (Group A) and single rotary file (Group B).
• Postoperative pain was quantified using the Visual Analog Scale (VAS) at 6, 24, and 48 hours.
• Statistical analysis included Chi-square and independent t-tests (P < 0.05).

Main Results:

• At 6 and 24 hours, Group B (single file) reported significantly lower VAS scores than Group A (multiple files) (P < 0.05).
• By 48 hours, pain levels were minimal in both groups, with no significant difference (P > 0.05).
• The single rotary file system demonstrated superior pain reduction within the initial 24 hours post-treatment.

Conclusions:

• Single rotary file systems are associated with significantly less postendodontic pain compared to multiple rotary file systems in single-visit endodontic procedures.
• Utilizing a single rotary file system may enhance patient comfort during the early postoperative phase of root canal treatment.
