NCT07069881

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.

    12 months after treatment

Secondary Outcomes (3)

  • postoperative pain

    day 1 after treatment

  • Cone Beam Computed Tomography Periapical Index Scores (CBCTPAI)

    12 months after treatment

  • The size of the periapical lesion
