3. Direct the patient to stick out the chest while dropping the chin down. While
holding the unit handles for stability, direct the patient to take a half step in
toward the vertical column of the X-Ray device into a position that feels as if
he/she is slightly leaning backward.
4. Direct the patient to the lips closed around the bite block during the exposure.
5. Direct the patient to swallow and note the flat position of the tongue. Request
that the patient suck in the cheeks, pushing the tongue into the correct
flat position against the palate and maintain this position throughout the
exposure.

The references pertinent to the potential risks
for the pediatric patients
1. I. ESPELID, I. MEJÀRE, K. WEERHEIJM: EAPD guidelines for use of
radiographs in children, P40-48. European Journal of Pediatric Dentistry
1/2003
Guidelines in dental radiology are designed to avoid unnecessary
exposure to X-radiation and to identify individuals who may benefit from
a radiographic examination. Every prescription of radiographs should be
based on an evaluation of the individual patient benet. Due to the relatively
high frequency of caries among 5-year-old children, it is recommended to
consider dental radiography for each child even without any visible caries or
restorations. Furthermore, radiography should be considered at 8-9 years
of age and then at 12-14, that is 1-2 years after the eruption of premolars
and second molars. Additional bitewing controls should be based on an
overall assessment of the caries activity/risk. The high-risk patient should
be examined radiographically annually, while a 2-3 years interval should be
considered when caries activity/risk is low. A routine survey by radiographs,
except for caries, has not been shown to provide sufcient information to
be justied considering the balance between cost (radiation and resources)
and benet.
