Brief summary
This clinical study evaluated the effects of different root canal disinfection procedures on postoperative pain. Patients requiring root canal treatment received one of several disinfection methods. Postoperative pain was assessed at 6,24, 48, 72 hours and on the 7th day using a standard pain scale. The aim of the study was to identify which method resulted in the least discomfort. Participation involved a single treatment session and short-term follow-up for pain measurement.
Interventions
PROCEDUREConventional Needle Irrigation
Root canals will be irrigated using a conventional syringe and needle technique with standard irrigant solutions. This method relies solely on manual delivery without activation devices.
PROCEDUREPassive Ultrasonic Irrigation
Root canals will be irrigated using passive ultrasonic activation, which uses ultrasonic energy to improve irrigant effectiveness and reduce microbial load beyond manual techniques.
PROCEDURESonic Irrigation
Root canals will be irrigated using a sonic activation device (e.g., EndoActivator) to enhance irrigant penetration and bacterial elimination compared to conventional irrigation.
PROCEDUREKTP Laser Disinfection
Root canals will be disinfected using a KTP laser following standard irrigation protocols. Laser application aims to provide enhanced antimicrobial effects not achievable with conventional or activated irrigation methods.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative Pain Intensity | 6, 12, 24, 48, and 72 hours after root canal treatment | Postoperative pain intensity assessed using the Visual Analog Scale (VAS), ranging from 0 to 100, where 0 indicates no pain and 100 indicates the worst pain imaginable; higher scores indicate greater pain severity |
