Objectives: This study evaluated the long-term post-treatment response of two root canal filling techniques. Materials and methods: Thirty-two mandibular first molars in patients diagnosed with pulp-periapical pathosis were instrumented and filled with either: (1) Matched-taper single- cone technique using ProTaper gutta-percha or (2) Warm vertical compaction technique with gutta-percha. AH Plus sealer was used in both groups. Periradicular alveolar bone density of the preoperative radiographs was compared to one-year postoperative recall radiographs using digital x-ray software. Oneyear postoperative subjective and objective pain assessments were evaluated and pain index was formulated. Results: Matched-taper single-cone technique showed a higher change in bone density (-1.67) than the warm vertical compaction technique (+0.99), a difference that was statistically non- significant. Gutta-percha warm vertical compaction exhibited less pain index than the matched- taper single-cone technique. Conclusions: Radiographically, both techniques had similar changes in periradicular bone density. Most of the recorded teeth with pain had periodontal problems or absence of permanent restorations.
