简要总结
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.
详细描述
This study is a prospective, parallel-group randomized controlled clinical trial designed to investigate the influence of obturation technique on postoperative pain experience and short-term treatment outcomes in single-rooted teeth with necrotic pulps.
All endodontic treatments will be performed by a single experienced operator to minimize inter-operator variability. After administration of local anesthesia and placement of rubber dam isolation, standardized access cavities will be prepared. Working length determination will be performed using an electronic apex locator and confirmed radiographically.
Root canal preparation will be carried out using rotary nickel-titanium instruments according to a standardized instrumentation protocol applied uniformly across all participants. Irrigation will be standardized for all cases and will include sodium hypochlorite during instrumentation and ethylenediaminetetraacetic acid (EDTA) for smear layer removal, followed by final canal irrigation and drying using sterile paper points. All procedural steps prior to obturation will be identical between groups to isolate the effect of obturation technique on postoperative outcomes.
Participants will be randomly assigned to one of two obturation techniques:
- Cold lateral condensation, performed using standardized gutta-percha cones and an epoxy resin-based sealer.
- Warm vertical condensation, performed using a thermoplasticized gutta-percha delivery system (Obtura II) in combination with gutta-percha and the same sealer.
