SP-27 The Mandibular First Premolar Anatomical Variations: A Microcomputed Tomographic View

A wide morphological variation exists in the root canal system of mandibular first premolars. This tooth is typically described as a single-rooted entity; however, two or three root canals can be found and are frequently described in the literature. In addition, this anatomical configuration includes also the presence of C-shaped canals, furcal canals and a high- percentage of apical deltas. This lecture will present results found during micro-CT analysis of more than 150 mandibular premolars presenting these anatomical variations. Morphometric parameters of the microanatomy that are critical for the surgical or nonsurgical treatment of these teeth will be presented.

At the conclusion, participants should be able to:

  •  Identify the main anatomical variations of the mandibular first premolar.
  •  Discuss the morphometric parameters of mandibular premolars presenting one, two or multiple canals.
  •  Recognize the different challenges of surgical and nonsurgical treatment of this particular anatomy.

SP-28 The Good, the Bad and the Ugly: BIG Mistakes in Practice and How to Manage Them Clinically

Endodontic treatment success depends on multiple treatment and biological variables. When these variables are violated, post-treatment disease can occur. This presentation will focus on endodontic mistakes by both the general dentist and endodontist and how to recover from those iatrogenic events. Topics to be discussed will include incorrect tooth diagnosis, separated files, root and furcal perforations, surgical mistakes, and management of the patient and general dentist after these unfortunate events occur. Several cases will be presented showing the presenters and other colleagues iatrogenic mistakes and the clinical technique that was employed to correct the situation.

At the conclusion, participants should be able to:

  •  Discuss why iatrogenic events occur in the field of endodontics.
  •  Discuss the different options available to manage iatrogenic nonsurgical and surgical endodontic events.
  •  Cite the literature that supports the management of these iatrogenic events.

SP-29 Periapical Microsurgery: Dentinal Defects Assessment and Management

Periradicular microsurgery has evolved into a precise, biologically based adjunct to nonsurgical root canal therapy. This lecture will go over the use of transillumination to help in assessing the resected root tips under the surgical operating microscope. Modern microsurgical protocols have shown excellent success rates in clinical studies. By analyzing the resected root tips, the astute clinician will know how to manage his surgical cases, obtain an ideal apical seal and have predictable outcomes.

At the conclusion, participants should be able to:

  •  Identify dentinal defects through a detailed microscopic evaluation of the root.
  •  Evaluate the root tip through the use of microscopic LED transillumination.
  •  Perform proper root management for a predictable microsurgical outcome and a predictable apical seal.
