Speaker: Bradford R. Johnson, D.D.S., M.H.P.E. The goal of this presentation is to serve as a brief overview of medical conditions and medications that may require treatment modification to ensure safe surgical treatment. The presentation will focus primarily on cardiovascular disease, selection of local anesthetic, anticoagulant therapy and hemostasis, diabetes, kidney and liver disease, immunosuppression, history of antiresorptive agent drug therapy, prosthetic joint replacement and relevant drug interactions.

Speakers: Mohamed I. Fayad, D.D.S., M.S., Ph.D.; Stephen P. Niemczyk, D.M.D.; William J. Nudera, D.D.S., M.S. Cone beam computerized tomography (CBCT) can provide a nondestructive real-time transfer of anatomic and morphologic information via a reconstructed digital image and a manipulatable user-friendly clinical interface for all phases of endodontic treatment.

SP-1: Speaker: Carlos Aznar Portoles, D.D.S., M.Sc. The success rate of endodontic surgical retreatment has shown to be above 90% when modern techniques are used. This presentation will focus on the surgical management of teeth that had previously been unsuccessfully surgically retreated. SP-2: Speaker: Bruce Y. Cha, DMD. In posterior maxilla, the sinus and posterior teeth are often intimately located and their mutual health intricately related. Clinicians should be aware of this interdependence when diagnosing and treating diseases in this region. SP-3: Speaker: Rachele Luciano, DMD. Post-operative pain can, in some cases, persist several months after endodontic therapy despite seemingly adequate treatment. When endodontic pathology has been ruled out, we must start thinking outside the box.

SP-39: Speakers: Keith R. Boyer, D.D.S. An enhanced revision of the endodontic revitalization technique to treat immature teeth with apical periodontitis will be presented. This includes the addition of a collagen-hydroxyapatite scaffold to the currently established revitalization technique, for previously untreated and retreatment cases. SP-40: Speaker: Maria A. Giron Cerrato, D.D.S. Dento-alveolar trauma is an unfortunate event occurring to patients as a result of accidents or sport-related injuries. This lecture will present various types of trauma cases in children and adults.

SP-1: Speaker: Daniel B. Green, D.D.S. Diagnosis and etiology of non-odontogenic pain will be discussed. Emphasis of the role played by components of the head and neck musculature as well as the etiology that differentiates pulpal and periapical disease from myofascial odontalgia and the influence of endodontic treatment will be emphasized. SP-2: Speakers: Allen Gaon, B.D.S., M.Sc. and Paul G. Cruci, D.D.S. Maxillary Sinusitis of Dental Origin (MSDO) accounts for between 10-12 percent and up to 40 percent of chronic maxillary rhinosinusitis cases. This presentation will explore the distinct pathophysiological, microbiological and differential diagnostic pathways of MSDO and relate them to the clinical situation.

Speaker: David J. Landwehr, D.D.S., M.S. At the conclusion, participants should be able to: List the characteristics and clinical features that distinguish non-odontogenic pain from that of endodontic origin. Use a systematic method to formulate a differential diagnosis of radiographic lesions found in the periradicular area. Explain the classification systems of orofacial pain to facilitate appropriate management.

CEX-7: Speaker: Mohamed I. Fayad, D.D.S., M.S., Ph.D. Accurate and confident treatment planning is an essential part of endodontic practice. In endodontology, clinical examination and diagnostic imaging are both essential components of the preoperative diagnosis. The problem of incorrect, delayed or inadequate endodontic diagnosis and treatment planning places the patient at risk and could result in unnecessary or inappropriate endodontic treatment. Periapical radiographs have been used to aid in the diagnosis of pathology and to help establish an appropriate a treatment strategy. Recently, a joint statement from the AAE/AAMOR that sets the guidelines for the use cone beam computed tomography in endodontic applications has been published. The aim of this presentation is to determine if CBCT is becoming an emerging standard of practice in endodontics. CEX-8: Speaker: Ernest W.N. Lam, DMD, MSc, PhD, FRCD(C). Three-dimensional imaging isn't just about generating a surface skin over image data to create a pretty picture. Rather, the power of 3-D imaging lies in the user's ability to tease out the characteristic features of disease by creating two-dimensional renderings from the 3-D image data.

Speaker: Zvi Metzger, D.M.D. Cracks and fractures that are found in vital and in endodonticaly treated teeth may present with a large variety of confusing signs and symptoms. The various clinical expressions of these two distinctive clinical conditions represent continuous processes that the operator happened to meet at a given time point. A vital tooth may present with a crack with no other symptoms than pain on chewing, then develop symptoms of pulpitis and eventually present with pulp necrosis and disappearence of pain on chewing, followed eventually by signs of apical periodontitis. An endodonticaly treated tooth may initially present with sensitivity and with a typical isolated narrow and tight periodontal pocket that is often inaccessible with a rigid metal probe and with no radiographic expression. Then, with advanced bone destruction of the cortical plate(s), it may be detectable on radiographs, as a radiolucency along the root or as a "halo." This occurs as soon as the extent of the cortical bone defect is larger than the silhouette of the root. This often represents a missed and delayed diagnosis.

Speaker: Asma Khan, B.D.S., Ph.D. It is well established that microbial infections play a key role in the initiation and progression of pulpal disease. The host response to pathogenic infection, which is critical to disease progression, is less understood. Understanding the molecular mechanisms that underlie the host response may lead to diagnostics that predict treatment outcome. The informed clinician can then choose which treatment option is best. This session covers recent advances in the molecular mechanisms of pain, the immune response and regeneration of the pulp-dentin complex.
