Cases in which patients felt nauseous during the radiographic taking with absolute isolation. We opted for the periapical radiograph positioned outside the patient's mouth, as proposed by Newman et al., 2002. The result allows interpretation, although with greater image overlaps.
Extraoral periapical radiography
In: Newman et al. Extraoral Radiographic Technique: An Alternative Approach. Journal of Endodontics. Vol. 29, 5, Jun 2003.
Introduction: The need for radiographs in all phases of endodontic therapy is well established. The clinician has a variety of aids to facilitate a diagnostic radiograph. Most of these aids (i.e. Rinn XCP holders , snap-a-ray, etc.) rely on conventional intraoral radiography. In this technique, the film is placed lingual to the tooth. The x-ray cone is placed directly buccal to the tooth, causing the x-ray beam to pass through the tissue, exposing the film (1).
Some patients cannot tolerate conventional intraoral radiography. This group has increased in size with the advent of
digital radiography. The digital sensor is larger and more rigid than standard x-ray film. The authors have found that certain patients have difficulty with the "added volume" of the sensor. An alternative procedure can be used while performing endodontic therapy for these patients.
Possible indications for this alternative technique include:
- Patients with intellectual disabilities
- Patients with exaggerated gag reflex
- Pediatric Patients
- Patients with dental phobia
- Trismus patients
