SP-8 Complete Healing after Multisonic Treatment in Perspective

Product not yet rated

CE Hours: 1.0

Description:According to methodologically sound studies, periapical healing after endodontic treatment of teeth with apical periodontitis advances progressively until about 75-85% of teeth are healthy (completely healed) several years after treatment. This outcome has not changed over decades of evolving nonsurgical treatment technologies because of inaccessible and resilient bacterial biofilms within the root canal systems.

    Explain the differences between short- and long-term healed rates after contemporary nonsurgical root canal treatment regimens.
  • Summarize the long-term healed rates reported by methodologically sound studies comprising the current best evidence for nonsurgical treatment.
  • Discuss interpretations of the reported short-term healthy rate after multisonic treatment.
