Speaker: Mohamad Fayad, D.D.S., M.S. Ph.D. | This evidence-based presentation will address the classification and diagnosis of different types of cracks and the role of CBCT imaging in these cases, as well as the prognosis and changes in treatment protocols and outcomes of cracked teeth.

Speaker: Mohamed Fayad, D.D.S., M.S., Ph.D.; Matthew C. Davis, D.D.S.| This evidence-based presentation will address the classification and diagnosis of different types of cracks and the role of CBCT imaging in these cases, as well as the prognosis and treatment outcomes of endodontically treated cracked teeth.

Speakers: Hagay Shemesh, B.D.S., Ph.D., Marco Aurelio. Versiani, D.D.S., M.Sc., Ph.D. Considering that modern endodontic treatment procedures are basically dependent upon the current-available shaping technology, a comprehensive knowledge of the causal-effect relationship between dentinal microcracks, motor-driven canal preparation and obturation techniques is of paramount importance to predict the optimal safeness of the whole endodontic procedure. This presentation seeks to critically appraise the methodological aspects and the outcome involved in the studies of dentinal microcrack formation after root canal preparation and obturation.

CEX-11: Speaker: Justin R. Kolnick, B.D.S. Laser therapy in dentistry is usually associated with removal of hard or soft tissues, or disinfection of the root canal system. LLLT is a laser or LED light therapy that improves tissue repair (skin wounds, muscle, tendon, bone, nerves), reduces inflammation and reduces pain wherever the beam is applied. CEX-12: Speaker: Dwayne D. Arola, Ph.D. This presentation will address the mechanical behavior of dentin, with special emphasis on the strength and fracture resistance. Details regarding spatial variations in the mechanical behavior within the root and crown will be described, as well as the changes that occur as a result of physiological aging.

Speakers: Louis H. Berman, D.D.S., F.A.C.D. & Anil Kishen, B.D.S., M.D.S., Ph.D. Fractured teeth, whether endodontically treated or not, are not an uncommon occurrence in clinical practice. As clinicians, it is imperative to recognize the clinical and radiographic parameters that may suggest a root fracture.

Authors: Siwen Wu, BDS, MDS, M Endo RCS (Edin), Hui Pau Lew, BDS, MDS, M Endo RCS (Edin), and Nah Nah Chen, BDS, MDS, MS The aim of the present study was to compare sonic activation using EDDY (VDW, Munich, Germany), passive ultrasonic irrigation (PUI), and mechanical activation using the XPendo Finisher (FKG Dentaire, La Chaux-des-Fonds, Switzerland) for the removal of calcium hydroxide from artificial grooves in straight root canals.

Authors: Sung Hyun Kang, D.D.S., M.S.D., Bom Sahn Kim, M.D., M.S., Ph.D., Yemi Kim, D.D.S., M.S.D., Ph.D. The aims of this study were to analyze the distribution and characteristic features of cracked teeth and to evaluate the outcome of root canal treatments (RCTs) for cracked teeth. The prognostic factors for tooth survival were investigated.
