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.
