Abstract

Objective: To evaluate the outcomes of single-visit endodontic treatment (SVE) in mandibular molars at the School of Dentistry and the 19-8 Hospital, during 2024–2025. Materials and Methods: A cross-sectional case series study was conducted on 42 mandibular molars treated with SVE. All cases were examined with cone-beam computed tomography (CBCT) and assessed for difficulty level using the American Association of Endodontists (AAE) case difficulty assessment form. Treatment outcomes were evaluated immediately after root canal obturation, postoperative pain was recorded at 1 day, 3 days, and 1 week, and clinical as well as radiographic follow-up was performed at 6 months. Results: Radiographic evaluation immediately after obturation showed 97.6% of cases achieved good quality. The mean instrumentation time was 32.38 ± 5.717 minutes, with a statistically significant difference between cases with difficulty scores <30 and those ≥30. VAS pain assessment showed that 78.6% of patients reported no pain after 24 hours; by 1 week, pain had markedly decreased, with 90.5% reporting no pain and only 4 cases reporting mild pain. At 6 months, successful treatment outcomes were achieved in 92.9% of cases. Conclusion: Single-visit endodontic treatment, when supported by advanced diagnostic tools such as CBCT and modern equipment and materials, provides favorable outcomes while minimizing treatment time and cost.
