Study Overview
Brief Summary
This study aims to evaluate the efficacy of the GentleWave® System compared to conventional methods in reducing postoperative pain in patients with necrotic pulp or requiring endodontic retreatment.
Detailed Description
New irrigation modalities such as the GentleWave® System, which integrates advanced multisonic ultrasound technology, have been developed to overcome limitations and improve root canal treatments success rates, by ensuring comprehensive cleaning while minimizing mechanical instrumentation. This system, featuring CleanFlow technology, optimizes the delivery of irrigants and promotes efficient root canal debridement. Postoperative pain is common, usually peaking within the first 24 hours after treatment and decreasing thereafter.
In the presence of necrosis, microorganisms can colonize anatomical complexities, such as isthmuses, ramifications and dentinal tubules causing symptoms such as pain, inflammation, and in some cases even odontogenic sinusitis. Conventional Syringe Irrigation (CSI), which delivers irrigants (NaOCl, EDTA) through a needle-syringe system, often fails to reach the entire working length and the intricate anatomy of the root canal. This inadequacy can result in residual bacteria and necrotic tissue, potentially compromising treatment efficacy and increasing the risk of treatment failure; furthermore, positive pressure exerted during CSI may cause the extrusion of irrigants beyond the apex, leading to complications.

Arms & Interventions
GentleWave
Featuring a handpiece CleanFlow technology, optimizes the delivery of irrigants: initially, a 3% NaOCl solution for 3 or 5 minutes, followed by a water rinse for 15 or 30 seconds, an 8% EDTA solution for 2 minutes, and a final distilled water rinse for 15 or 30 seconds. These solutions penetrate and eliminate necrotic tissue, debris, biofilm and bacteria, leaving the dentin intact and preserving the tooth structure. Use of the Gentlewave system is contraindicated in teeth with immature apices, teeth with insufficient coronal structure, and teeth with root apices that extend into the maxillary sinus.
Intervention: GentleWave (Other)
Control group
Conventional Syringe Irrigation (CSI), which delivers irrigants (NaOCl, EDTA) through a needle-syringe system. After local anesthesia, the tooth will be isolated with a rubber dam. The pulp chamber will be accessed using ultrasound, eliminating all cavities, restorations with microfiltration or creating access through metal crowns. All canals will be cleaned and shaped with rotary files until at least a canal size of 20.6 or 25.04 is achieved within 0.5 to 1 mm of the apical end. Between each file, 6% NaOCl will be used to disinfect and clean the waste channels. Each canal will then be soaked in 17% EDTA for 1 minute, rinsed with 6% NaOCl, and finally subjected to a final saline rinse. The canals will be filled with root canal sealant and gutta-percha.
Intervention: Conventional Protocol (Other)
Outcomes
Primary Outcomes
To evaluate whether using the Gentlewave system demonstrates a significant reduction in the level of postoperative pain after endodontic treatment measured by the VAS (Visual Analog Scale).
Time Frame: 24 hours
Pain measurements were made using a VAS (Visual Analog Scale of 0-10. Where the value of 0 represented absence of pain and value 10 represented the greatest intensity of pain.
Secondary Outcomes
No secondary outcomes reported
