S-6 Periapical Microsurgery: De Rigueur Root-end Assessment & Management of Dentinal Defects

5 (1 vote)

CE: 1.0

A thorough microscopic inspection of the root-end complex through LED transillumination and staining should be a routine prescribed custom to all clinicians performing this detailed procedure. This De Rigueur approach gives clinicians a view to manage dentinal defects making periapical microsurgery a precise, biologically based adjunct to nonsurgical root canal treatment. This presentation will cover the direct vision concept that will help clinicians predictably assess and manage the root-end complex through the use of magnification, transillumination and staining. Modern microsurgical protocols have shown excellent success rates in clinical studies. By analyzing the resected root tips, the astute clinician will be able to know how to manage surgical cases, obtain an ideal apical seal and offer predictable outcomes.


At the conclusion, participants should be able to:

  • Recognize how endodontists can best position themselves, their staff and their microscope to work through a direct vision approach.
  • Identify dentinal defects through a detailed microscopic evaluation of the root-end complex through LED transillumination and staining.
  • Demonstrate an ideal apical seal through proper root-end management of dentinal defects and apical anatomy.
