About this trial
Brief Summary
Postoperative pain is a common complication following root canal treatment, particularly in necrotic teeth with asymptomatic apical periodontitis. Although obturation technique has been suggested as a contributing factor to postoperative discomfort, direct clinical comparisons between commonly used methods remain limited. Cold lateral condensation has traditionally been considered the standard obturation technique, while warm vertical obturation systems such as Obtura II have gained popularity due to their potential for improved adaptation of gutta-percha.
This randomized controlled clinical trial aims to compare postoperative pain experience and treatment outcomes following cold lateral condensation and warm vertical obturation in single-rooted necrotic teeth. Postoperative pain will be assessed during the early healing period, along with patient-reported outcomes and short-term clinical and radiographic healing. The results of this study are expected to provide clinically relevant evidence to support evidence-based obturation technique selection and improve patient comfort in endodontic practice.

Treatments tested in this trial
Warm Vertical Condensation (WVO)
Procedure/SurgeryFollowing standard endodontic cleaning and shaping with rotary instrumentation and irrigation, canals will be obturated using the warm vertical condensation technique. After placement of a master cone coated with AH Plus sealer, heat is applied to soften and vertically compact the gutta-percha within the canal. The Obtura II system will be used to backfill the canal with thermoplasticized gutta-percha, ensuring three-dimensional adaptation and dense filling of the root canal space.
Cold Lateral Condensation (CLC)
Procedure/SurgeryFollowing standard endodontic cleaning and shaping with rotary instrumentation and irrigation, canals will be obturated using the cold lateral condensation technique. A master gutta-percha cone coated with sealer (AH Plus) will be inserted, and accessory cones will be compacted laterally using spreaders until the canal is fully obturated. This technique is widely regarded as the traditional standard method for root canal obturation.
