Nestor Cohenca, D.D.S.

Biography

Dr. Cohenca completed the endodontic program at the Hebrew University in Jerusalem cum laude and received the Best Graduate Student Award. He then served 11 years on faculty at the school while maintaining a private practice limited to endodontics. From 2003 to 2005 he served as a clinical assistant professor and coordinator of Trauma and Sports Dentistry at University of Southern California.  Thereafter, Dr. Cohenca joined the University of Washington where he completed his endodontic certificate in 2008 and served as Tenured Professor of Endodontics and Pediatric Dentistry from 2005-2014. He served as Director of Endodontics and Trauma at the Center for Pediatric Dentistry, and Seattle Children’s Hospital. Currently he serves as Affiliate Professor at the University of Washington and maintains a private practice limited to Endodontics in Bellevue and Everett, WA. He is a Diplomate of the Israel Board of Endodontics and the American Board of Endodontics. Dr. Cohenca is a Fellow of the IADT and received an honorary membership to Omicron Kappa Upsilon National Dental Honor Society. He has published more than 70 peer-reviewed articles, 10 chapters and a new book entitled “Disinfection of Root Canal Systems: The Treatment of Apical Periodontitis”. Cohenca serves as President-Elect of the International Association of Dental Traumatology. He is well known as one of the experts on root canal disinfection, CBCT, dental traumatology and Endo-Pedo related topics.

Dr. Cohenca is fluent in Spanish, Portuguese and Hebrew, and has a strong background in dental traumatology.

Available Sessions

  • Diagnosis and Treatment of Traumatic Dental Injuries
    Topic: Traumatic Injuries Diagnosis & Treatment
    Learning Objectives:

    At conclusion, participants should be able to:

    • Identify the epidemiological and predisposing factors of dental trauma.
    • Classify the different traumatic injuries.
    • Implement the most recent, state-of-the-art diagnostic and therapeutic guidelines for traumatized and avulsed teeth.
    • Describe the etiology and diagnosis of root resorption.
    • Develop a comprehensive approach for the treatment of ankylosed teeth.
    • Describe new concepts and approaches on vital and nonvital pulp therapy. Know when and what to refer.

    The incidence of dental trauma is higher in children and adolescents. The first clinical and radiographic examination of the traumatized patient is crucial to determine the diagnosis, severity and treatment plan, as well as to create a baseline for follow-up. Traumatic lesions include coronal and root fractures, subluxations, luxations and teeth avulsions. Common complications are pulp necrosis and root resorption. Treatment is complex, time consuming, expensive and requires multidisciplinary approaches, such as endodontic and periodontal treatments, surgery, orthodontic and esthetic coronal restoration. New approaches for prevention, diagnosis and treatment of traumatized teeth will be thoroughly discussed and illustrated.

  • Treatment of Ankylosed Teeth, Decoronation and GTR
    Topic: Resorption
    Learning Objectives:

    At conclusion, participants should be able to:

    • Describe the etiology and diagnosis of replacement root resorption.
    • Apply current therapeutic guidelines for avulsed teeth.
    • Develop a comprehensive approach for the treatment of ankylosed teeth.

    Replacement resorption and ankylosis are frequently diagnosed following avulsion and severe intrusive luxation. The treatment of ankylosed permanent incisors following dental trauma presents a clinical challenge, particularly when it involves a growing child due to the high risk of infraposition and undevelopment of the alveolar bone. New approaches for the treatment of ankylosed teeth, including decoronation and bone augmentation for the preservation of alveolar ridge prior to permanent prosthetic reconstruction will be thoroughly discussed and illustrated.

  • Effectiveness of Single- Versus Multiple- Endodontic Treatment Visits
    Topic: Single vs Multiple-Visit Endodontics
    Learning Objectives:

    At conclusion, participants should be able to:

    • Review scientific evidence related to single- versus multiple-visit endodontic therapy.
    • Understand new concepts of canal irrigation and disinfection.
    • Apply a therapeutic clinical flow chart in their practice.

    Although successful elimination of bacteria from the root canal system remains the most important therapeutic goal, there is no consensus as to the most effective clinical approach. The literature related to single versus multiple visits differs in several important areas. This lecture will provide a comprehensive critical review of the literature and propose a clinical flow chart that takes into consideration the preoperative diagnosis, infection control procedures and their effect on the outcome of endodontic therapy.

  • Root Canal Disinfection
    Topic: Root Canal Irrigation, Disinfection & Instrumentation
    Learning Objectives:

    At conclusion, participants should be able to:

    • Review scientific evidence related to efficacy of irrigation at the apical third.
    • Describe new concepts of canal irrigation and disinfection.
    • Apply a therapeutic clinical flow chart in their practice.

    The primary aim of endodontic therapy in both vital and necrotic teeth is the reduction in the number of bacteria and microbes in the root canal system that prevents healing of periradicular periodontitis. Although this criteria seems clear, there is little consensus on how to reach these goals. Despite the advances on mechanical shaping using newly developed NiTi rotary files, the outcome of endodontic therapy remained unchanged, mainly because the new files cannot reduce or eliminate the microbial contamination within the complex anatomy of root canal systems. New irrigant delivery systems have been recently developed to overcome these challenges. Indications, efficiency and predictability of these systems for root canal disinfection will be thoroughly analyzed and discussed.
