Study Notes

  • An appliance with metal clasps can interfere with the radiolucency of teeth and surrounding tissues, so it should be removed during radiographic imaging.
  • The obturator needs to be removed during exposure of radiographic images and during dental hygiene therapy in order to access complete calculus and biofilm removal.
  • Sleeping with the obturator in place increases the risk for demineralization and dental caries in the abutment teeth.
  • Marking is required by law in some countries and in most states of the United States.
  • For forensic dentistry or for identification of victims of war, such disasters as flood or fire, or transportation catastrophes, the dentition has been used increasingly as a means of identification.
  • Prompt identification can be urgent when an individual is found unconscious from illness or injury or is suffering from amnesia as a result of psychiatric or traumatic causes.
