Peter Z. Tawil, D.M.D., M.S.


Dr. Peter Z. Tawil started out his education in Mechanical Engineering at McGill University. He continued his studies in Dentistry where he obtained his DMD at the Université de Montréal and his AEGD certificate at the University of Rochester. After discovering his passion for Endodontics, he completed his Masters in Endodontics at the University of North Carolina at Chapel Hill. Upon completion of his studies in Chapel Hill, Dr. Tawil worked as a specialist in private practice for several years in Québec and in North Carolina. While in private practice he served as a part-time faculty at multiple Universities. With his active involvement in Endodontic research, Dr. Tawil has several publications and received several research grants and awards. His main research focus is in Periapical Microsurgery, Endodontic Instruments & Materials. Dr. Tawil serves as a speaker for the American Association of Endodontists and lectures nationally and internationally. He’s currently a Faculty at the University North Carolina at Chapel Hill where he serves as the Graduate Program Director, he serves as a mentor for the College of Diplomates of the American Board of Endodontics and as an examiner for the Royal College of Dentists of Canada. Additionally, he founded the Tawil Humanitarian Dental Fund that supports annual international volunteer dental mission trips with his residents at UNC.

Available Sessions

  • Access: The Quest for the Extra Canal
    Topic: Endodontic Access
    Learning Objectives:

    At conclusion, participants should be able to:

    • List the tools needed to facilitate endodontic access.
    • Describe the number of canals that a tooth can contain.
    • Describe when to keep looking for extra canals and when to stop.
    • Describe the landmarks inside a tooth.
    • Describe the internal anatomy of a tooth.

    From MB2 in uppers molars to MM in lower molars, this course clarifies the steps on how to find all canals inside a tooth. The key to finding all the canals in a specific tooth lies in our ability to read and understand the internal anatomy and the map that the floor of each tooth offers.

  • Endodontics – Revolution in instrumentation and management of complications
    Topic: Root Canal Irrigation, Disinfection & Instrumentation
    Learning Objectives:

    At conclusion, participants should be able to:

    • Define the new metallurgy revolution in endodontics and the new files using the technology
    • List the benefits of this new metallurgy, what it offers and when to use it
    • Identify how to avoid and how to manage endodontic file separation.
    • Describe the techniques used by endodontists for separated file removal and the limitations of these techniques.
    • Identify how to avoid and how to repair a perforation
    • Identify how to avoid and how to manage a bleach irrigation accident
    • Identify hot to avoid and how to manage endodontic complications.

    This course is intended for the clinicians who desire to prefect their knowledge in Endodontics. The recent revolution in NiTi metallurgy will be reviewd along with the pros and cons on the new instruments. Furthermore, endodontics treatment is a challenging procedure that involves potential complications. This course will discuss how to minimize and how to manage these complications

  • Immediate and long term management of dental trauma
    Topic: Dental Trauma
    Learning Objectives:

    At conclusion, participants should be able to:

    • Conduct proper management of crown fractures, root fractures, concussions, subluxations injuries, luxation injuries and avulsions.
    • Discuss the potentional use of corticosteroids in the management of traumatic injuries.
    • Identify how and when to do a Regeneration procedure on the immature necrotic pulp.
    • Identify how and when to do an Apexification procedure on the immature necrotic pulp.
    • Describe the pros and cons of Regeneration vs. Apexification.

    From simple crown fractures to complicated avulsions, this course reviews the management and treatment of all dental traumatic injuries. Furthermore, this lecture will present the long term management of traumatized teeth along with the treatment options for the necrotic immature pulp chambers. Regeneration procedures will be presented and compared to apexification procedures along with the pros and cons of each.

  • Periapical Microsurgery: An Update on Microsurgical Endodontics
    Topic: Periapical Microsurgery
    Learning Objectives:

    At conclusion, participants should be able to:

    • Define the indication for periradicular microsurgery.
    • Define the differences between traditional techniques and modern microsurgical techniques.
    • Describe  the importance of new microsurgical instruments.
    • Describe the different flap designs and their indications.
    • Discuss several techniques for proper hemostatis
    • Perform proper root tip assessment.
    • Perform proper root tip management.
    • Explain how to achieve an ideal root-end cavity preparation
    • Define modern root-end filling materials that are available and how to place them.
    • List the different suture types and materials.
    • Perform proper suture designs.
    • Explain post-surgical healing and when grafting is indicated.
    • Perform proper post-surgical patient management.

    Periradicular surgery has evolved into a precise, biologically based adjunct to nonsurgical root canal therapy. This lecture will cover the significant improvements that have been made in the development of new instruments, materials and techniques. Modern microsurgical protocols have shown excellent success rates in clinical studies. A recent study showed a distinct difference in outcome when modern microsurgical techniques were compared to the older traditional techniques in performing apical surgeries. This is mostly due to proper assessment and management of the root tip complex. Every astute dental clinician has to keep in mind that the decision to treat a tooth with apical microsurgery or to replace it with an implant must be based on factors other than treatment outcome since both options have shown similar healing results.

  • Obturation: Root Canal Aesthetic
    Topic: Root Canal Obturation
    Learning Objectives:

    At conclusion, participants should be able to:

    • Describe the importance of root canal disinfection prior to obturation.
    • Describe the goals of a root canal obturation.
    • Describe the different endodontic sealers.
    • Describe the different obturation materials.
    • Describe different root canal obturation techniques available and identify the pros and cons of each system.
    • Master the warm vertical and continuous wave obturation techniques.
    • Assess the tools needed to facilitate endodontic obturation.
    • Describe post-obturation coronal leakage, the use of intra-orifice plugs and the importance of a well sealing final restoration.

    The obturation phase of a root canal is the final step of the treatment from which we judge the quality of our disinfection on the radiograph. Thus, the aesthetic part of our treatment comes out in this final step. This lecture covers the different sealers, obturation materials, instruments, machines and techniques. This course will go over the warm vertical and continuous wave obturation techniques, using sequential pictures and step-by-step tips.
