The answer is: C


8- Differentiate between external and internal root resorption:

  1. internal resorption is contiguous with the canal, and external resorption is superimposed on x-ray examination.
  2. internal resorption appears superimposed, and external resorption appears contiguous with the canal on x-ray examination.
  3. the apex iocator is very useful.
  4. internal resorption is larger in size.






The answer is: A

The answer is: C



10- The prognosis is compromised:

  1. when patient presents with pain.
  2. when patient experiences interappointment pain.
  3. with class III mobility and loss of bone support.
  4. for molar teeth.







The answer is: C

  4. pulp/periodontal, oral surgery, caries control.







The answer is: C


12- Single-visit root canal therapy:

The answer is: A


15 - Patients scheduled for retreatment:

  3. should expect surgical intervention.
  4. may complain of thermal response on an adjacent tooth.







The answer is: D
