    Topic: Differential Diagnosis
    Learning Objectives:
    • Define the terms and classifications of teeth with cracks and fractures.
    • Give a clinical prognosis for teeth with reversible/irreversible pulpitis, necrotic pulp and a cracked marginal ridge.

    The diagnosis, treatment and prognosis of cracked teeth from an endodontic perspective will be discussed along with the definitions of terms. The diagnostic procedures and tests will be explained, and rationale and methodology used to gather the data will be presented with respect to pulpal and periapical diagnosis.

    One- to three-hour lecture.

  • Endodontic Instruments in the Operatory
    Topic: Nonsurgical Endodontic Treatment & Retreatment
    Learning Objectives:
    • Define a basic set of instruments appropriate for these procedures including diagnosis, emergency treatment, canal preparation, obturation and bleaching.
    • Describe the general physical properties of endodontic instruments and show how these characteristics are related to their use.
    • Describe the design (longitudinal, cross-sectional and tip configuration) of the more common canal preparation instruments and their mode of use.
    • Explain the basis for sizing and taper (standardization) of hand-operated instruments.
