Brief Summary
This randomized, controlled, double-blinded clinical trial aims to directly compare the efficacy of Sonically Activated Irrigation (SAI) versus Passive Ultrasonic Irrigation (PUI) in the root canal treatment of teeth with chronic apical periodontitis, analyze potential influencing factors, and thereby identify a highly effective and safe root canal irrigation protocol. The ultimate goal is to provide an evidence-based rationale for optimizing irrigation technique selection and overall treatment strategies for chronic apical periodontitis.

Outcome Measures
Primary Outcomes (1)
Therapeutic Effect Evaluation
1. Success: A tooth is considered successfully treated when it is asymptomatic, showing no signs of apical infection such as percussion pain, mobility (loosening), tenderness, mucosal swelling, sinus tract, or fistula. Radiographically, the periapical radiolucency must demonstrate either absence or significant reduction. 2. Failure: Treatment is deemed unsuccessful if the tooth remains symptomatic or develops new symptoms of apical infection (e.g., pain, fistula). Radiographically, the size of the periapical radiolucency remains unchanged or shows enlargement.

Sonic-Activated Irrigation
EXPERIMENTALPassive Ultrasonic Irrigation
ACTIVE COMPARATORInterventions
Sonic-activated irrigation was performed using the polymer tip (Eddy™, VDW, Germany) activated by an airscaler handpiece.
Passive ultrasonic irrigation was performed using the ultrasonic tip (ACTEON, France) attached to an ultrasonic device (P5 Newton™, ACTEON, France)
