Overview

This study demonstrates improved penetration depth of sodium hypochlorite in dentin with passive ultrasonic irrigation, suggesting enhanced efficacy for endodontic procedures.

Key Points

  • The 6 × 10 s passive ultrasonic irrigation cycle significantly increased sodium hypochlorite penetration in all sections.
  • Conventional needle irrigation resulted in lower penetration depth compared to all passive ultrasonic irrigation groups.
  • The 3 × 20 s protocol showed superior effectiveness in reaching the apical third of dentin.
  • Optimizing ultrasonic irrigation parameters can lead to more predictable results in endodontic treatment.
