Intraoral Radiographic Examination



Iannucci & Howerton (pp. 152-153)
A radiographic inspection of teeth and
intraoral adjacent structures
Requires the use of intraoral image receptors

Intraoral receptor
• Receptor that is placed inside the mouth and is used to
examine the teeth and supporting structures

Diagnostic Criteria for Intraoral
Radiographs






Iannucci & Howerton (p. 153) (Box 16-1)
Radiographs must show images with optimum density,
contrast, definition, and detail.
Must show images with the least amount of distortion
possible.
The CMRS must include radiographs that show all
tooth-bearing areas.
Periapical radiographs must show the entire crowns and
roots of teeth being examined, as well as 2 to 3 mm
beyond the root apices.
Bite-wing radiographs must show open contacts.

Extraoral Radiographic Examination



Iannucci & Howerton (p. 153)
A radiographic inspection of large areas of
the skull or jaws
Extraoral receptors

Receptors that are placed outside the mouth

Prescription of Dental Radiographs


Iannucci & Howerton (p. 154) (Table 5-1)
Prescribing is based on the individual needs
of the patient.

CMRS is appropriate when a new adult patient
presents with clinical evidence of generalized
dental disease or a history of extensive dental
treatment.
