Questions and Answers

What is the primary reason why achieving the objective of complete removal of byproducts from the canal space may be difficult?

  • Contrast media used in radiography complicates the process.
  • The apical foramen diameter remains consistent in all teeth.
  • The internal anatomy of teeth is too simple to navigate effectively.
  • Residual bacteria and debris are usually tightly packed in the canal space. (correct)
  • Why may residual bacteria and debris persist in the canal space despite efforts to remove them?

  • Resin injection causes entrapment of bacteria and debris.
  • Scanning electron microscopy complicates visibility.
  • The complexity of the internal anatomy of teeth creates hiding spots. (correct)
  • The apical foramen is always easily accessible for cleaning.
  • What study method revealed considerable variation in the diameter of the apical foramen in teeth?

  • Laboratory radiography with contrast media
  • Tooth sectioning
  • Dissection microscopy (correct)
  • Scanning electron microscopy
