Overview

Randomized trial reveals reduced surgical time and early postoperative swelling with CBCT in apical periodontitis, suggesting 3D imaging aids surgical planning without altering 12-month healing.

Key Points

  • To evaluate whether supplementary cone beam computed tomography improves patient quality of life, operating time, and 12-month healing compared to periapical radiography alone in endodontic microsurgery.
  • Conducted a parallel-group randomized clinical trial (NCT04333940) allocating 52 patients (88 teeth) with persistent apical periodontitis to preoperative periapical radiography (PR) alone or PR combined with cone beam computed tomography (CBCT).
  • Assessed quality of life over the first postoperative week via the Modified Shugars questionnaire, recorded surgical duration, and evaluated radiographic healing at 12 months using Molven's and modified PENN 3D criteria.
  • Patients in the CBCT group experienced significantly less swelling during the first 3 postoperative days, took fewer analgesics on days 2 and 3 (p < 0.007), and had significantly shorter mean surgical durations (p < 0.05).
  • At the 12-month follow-up (N=50), radiographic healing was achieved in 96.2% of the PR group and 95.8% of the CBCT group, demonstrating no statistically significant difference in therapeutic success.
