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”.

Available Sessions

  • Clinical Applications of Focused-Field Cone-Beam-Computed Tomography in Endodontics—Time to Change Strategy!
    Topic: Imaging

    Endodontic therapy depends on diagnostic radiographs and image-guided treatment. Focused-Field Cone-Beam-Computed Tomography is a new technology that produces a three-dimensional digital image at a reduced cost and radiation for the patient comparing to any other 3-D imaging system. It is designed to allow for high resolution imaging of the hard tissues of the maxillofacial region with a faster and easier image acquisition. By providing a 3-D representation of the maxillofacial tissues in a cost- and dose-efficient manner, a better preoperative assessment can be obtained for diagnosis and treatment; thus, increasing the outcome of the therapy and avoiding further complications. This lecture will thoroughly illustrate and review clinical application of Focused-Field CBCT technology for the endodontic practice.

    Three- to six-hour lecture.

  • Root Canal Irrigation and Disinfection
    Topic: Nonsurgical Endodontic Treatment & Retreatment

    During the last decade, great emphasis has been placed on the increased ability to clean and shape canals with the newly developed nickel-titanium rotary files. However, even with these advancements, the outcome of root canal therapy remained unchanged mainly because the new files cannot predictably eliminate the microbial contamination within the complex anatomy of root canal systems. For immature teeth with apical periodontitis the challenge is even greater affecting the long-term treatment outcome. The efficacy, safety and predictability of root canal disinfection will be thoroughly discussed with evidence-based research. At conclusion, participants should be able to understand new concepts of canal irrigation and achieve predictable disinfection of the root canal systems.

    Three- to five-hour lecture.

  • Root Resorption: Prevention, Diagnosis and Current Treatment Modalities
    Topic: Resorption

    Root resorption remains a clinical challenge with regard to diagnosis, treatment and prognosis. Root resorption is classified based on location, etiology and pathogenesis. Treatment is complex, time consuming, expensive and requires multidisciplinary approaches including endodontic and periodontal treatments, surgery, orthodontics and esthetic coronal restoration. During this presentation, the diagnosis, treatment and prognosis of the different types of root resorption will be thoroughly discussed and illustrated in light of new treatment modalities.

    Three- to five-hour lecture.

  • Multidisciplinary Approach for Diagnosis, Treatment and Prevention of Dental Trauma
    Topic: Traumatic Injuries Diagnosis & Treatment

    The incidence of dental trauma due to falls, sports, automobile accidents and violence has been reported at 28.9 % for the first decade of life, 44.2 % for the second decade, followed by a sharp decrease in incidence thereafter. Treatment is often complex, time consuming, expensive and requires multidisciplinary approaches such as endodontic and periodontal treatments, surgery, orthodontic movements as well as esthetic coronal restoration. Therefore, this course is aimed at all oral health care providers, including general dentists, specialists, hygienists and staff members.

    This course can range from three to 16 hours (two days).

  • Focused Field Cone Beam Computed Tomography in Endodontics. Time to change strategy!
    Topic: Imaging
    Learning Objectives:
    • Describe clinical applications of CBCT in the endodontic practice.
    • Review the potential benefit of CBCT technology for diagnosis and treatment plan.
    • Discuss the impact on treatment outcome and improved predictability.

    Endodontic therapy depends on diagnostic radiographs and image-guided treatment. Focused Field Cone Beam Computed Tomography (CBCT) is a new technology that produces a three-dimensional digital image at a reduced cost and radiation for the patient comparing to any other 3-D imaging system. It is designed to allow for high resolution imaging of the hard tissues of the maxillofacial region with a faster and easier image acquisition. By providing a 3-D representation of the maxillo-facial tissues in a cost and dose efficient manner, a better preoperative assessment can be obtained for diagnosis and treatment; thus, increasing the outcome of the therapy and avoiding further complications. This lecture will thoroughly illustrate and review clinical application of Focused Field CBCT technology for the endodontic practice.

    one-to-two-hour lecture.

  • Treatment of immature teeth with pulp necrosis and apical periodontitis. Regeneration or repair?
    Topic: Regenerative Endodontics
    Learning Objectives:
    • Describe the clinical and biological implications of treatment of immature teeth with pulp necrosis.
    • Review the concept of pulp revascularization for treatment of immature teeth with necrotic pulps
    • Develop the most predictable treatment plan for immature teeth with necrotic pulps to obtain a positive outcome.

    Immature teeth with apical periodontitis present a clinical challenge due to the presence of short undeveloped root structures, thin dentinal walls, and wide open foramens. In addition, disinfection and obturation of the root canal system is risky and unpredictable, affecting the long-term treatment outcome. In view of this difficulties and taking in consideration the polymicrobial nature of root canal system, authors have proposed the use of a mixture of antibiotics to treat the diverse endodontic microflora. This novel procedure exploits the full potential for revascularization and tissue ingrowth toward dentin deposition and stronger roots able to withstand fracture. This presentation will discuss current evidence-based research with emphasis on the biological implications of such antimicrobial therapy. Alternative disinfection protocols will be presented and correlated with the development of a connective tissue repair consistent with pulpal revascularization.

    one-to-two-hour lecture.

  • Multidisciplinary Approach for Diagnosis, Treatment and Prevention of Dental Trauma
    Topic: Traumatic Injuries Diagnosis & Treatment
    Learning Objectives:
    • Implement the most recent, state-of-the-art diagnostic and treatment modalities.
    • Describe current evidence-based therapeutic guidelines for dental trauma and root resorption.
    • Develop effective strategies for preservation and augmentation of alveolar ridge augmentation toward final prosthetic rehabilitation.

    The management of dental trauma remains a significant clinical challenge affecting health-care providers and patients alike. Falls, accidents and sport related injuries are the most frequent causes of dental trauma, with maxillary centrals being the most commonly injured teeth. Overall, the estimated prevalence of injuries among children is 30%. Patients can present with a wide variety of injuries ranging from crown or root fractures, to injuries to the supporting periodontal structure, including luxations and avulsions. Treatment is often complex, time consuming, expensive and requires multidisciplinary approaches such as endodontic and periodontal treatments, surgery, orthodontic movements as well as esthetic coronal restoration. This course aims to all oral health care providers, including general dentists, specialists, hygienists and staff members. New approaches for prevention, diagnosis and treatment of traumatized teeth will be thoroughly discussed and illustrated using advanced 3D technology for diagnosis and treatment planning.

    Dental Trauma is broad and extensive. Presentations may range from a 60 min lecture focused on a specific topic or a 1 – 2 days comprehensive course.
