S-8 CBCT Assessment of Healing After Apical Microsurgery: The Third Dimension (Part 2)

CE Hours: 1 CE hour 

Apical surgery using the modern technique, i.e. microsurgical principles, is an established treatment protocol of persistent apical periodontitis when conventional endodontic retreatment is not possible, is associated with risks, or is denied by the patient. The outcome of apical surgery is commonly evaluated with a clinical and radiographic examination one year after the intervention. Two-dimensional radiography (periapical radiography) is currently the method of choice with regard to healing assessment of the former radiolucency, applying healing criteria established by Rud et al. and Molven et al. in the 1970s and 1980s. Recently, CBCT has become an important tool in the management and evaluation of endodontic problems. With regard to outcome assessment of apical surgery, CBCT allows a more thorough and unparalleled evaluation, particularly in the oro-facial dimension, thus giving new insight in the tissue regeneration occurring around the cut root face and of the access windows. The lecture describes in detail the benefit of post-surgical CBCT analysis and also reports the latest data from our research group regarding three-dimensional appraisal.

At the conclusion, participants should be able to:

  • Describe the conventional healing criteria for radiographic outcome assessment following apical surgery.
  • List the new healing criteria using CBCT for radiographic outcome assessment following apical surgery.
  • Apply 3-D healing analysis based on CBCT imaging of teeth treated with apical surgery.
