Comparison of Single-Visit Endodontic Treatment Outcomes Using Continuous Wave Condensation and Single-Cone Obturation Techniques
Sponsor: Hue University of Medicine and Pharmacy
Summary
The goal of this clinical trial is to compare two root canal obturation techniques for endodontic treatment in patients aged 15 to 56 years with irreversible pulpitis. The main questions it aims to answer are: 1. Does continuous wave condensation differ from the single-cone technique in obturation time? 2. Does continuous wave condensation differ from the single-cone technique in obturation quality, postoperative pain, and 6-month treatment success? Researchers will compare continuous wave condensation with single-cone obturation to see whether one technique provides better sealing quality, shorter treatment time, less postoperative pain, or higher clinical success. Participants will: * Receive endodontic treatment for teeth diagnosed with irreversible pulpitis. * Undergo root canal preparation with Reciproc Blue R25. * Have canals obturated using either continuous wave condensation or the single-cone technique. * Be evaluated for obturation time, radiographic quality immediately after treatment, postoperative pain at 4, 24, 48, and 72 hours, and clinical-radiographic outcome at 6 months.

Interventions
Continuous Wave Condensation
Continuous Wave Condensation (CWC) - Specific Protocol: * EQ-V system (Meta Biomed, South Korea) - NOT System B, Touch'n Heat, or generic pluggers * Precise heat activation: 230°C (manufacturer setting for optimal flow) * Cutting tip positioned 4-6 mm short of working length (prevents over-compaction) * Gutta-percha cone tip pre-trimmed 0.5-1 mm (ensures precise apical control) * Two-stage process: apical hand condensation + thermoplastic backfill * Time measured from cone insertion to final radiograph (includes verification)
Single-Cone
* Matched master cone to Reciproc Blue R25 preparation (size/exact tug-back) * Heat trimming at/below orifice (minimizes coronal excess vs cold cutting) * NO supplementary cones or lateral compaction (pure single-cone) * Sealer: AH Plus (Dentsply) - not bioceramic or other brands
