NS-20 Cracks and Fractures in Vital and Endodonticaly Treated Teeth

5 (1 vote)

CE Credits: 1.5

Program Overview:

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.  

At the conclusion, participants should be able to:

  • List and describe the signs and symptoms of cracked and fractured vital teeth and explain their sequence of appearance.
  • List and describe the signs and symptoms of a vertical root fracture in an endodonticaly treated tooth and explain their sequence of appearance.
  • Explain the nature of the radiolucency that appears with long-standing vertical root fractures and explain why they often represent a missed or delayed diagnosis.
