Product not yet rated

CE Hours: 1.0

Description: To address the shortage of clinical outcome studies on contemporary root canal disinfection methods, this prospective cohort study assessed healing of apical periodontitis (AP) after use of the GentleWave (GW) system or Ultrasonic Activation (UA) combined with negative pressure irrigation (NPI).

At the conclusion of this article, the reader will be able to: 

  • Identify key procedural differences between the GentleWave and UA + NPI protocols used in molar root canal disinfection.
  • Recognize potential limitations in using conventional radiographs versus CBCT for assessing healing outcomes.
  • Evaluate the appropriateness of the prospective cohort design and statistical analyses used to compare treatment outcomes.
