DAP (Dose Area Product) is a quantity used in assessing the radiation risk from
diagnostic X-ray examination procedures. It is defined as the absorbed dose multiplied
by the area irradiated, expressed in gray square centimeters (mGy·cm2). Despite the
limitation, DAP is the best way to predict effective dose value and currently the most
convenient method for patient doses monitoring.
▪ PHE (Public Health England) recommends that any national reference dose that
achievable dose (DAP) value of 250 [mGy·cm2] for a clinical protocol for a
standard male patient.

SMI will be one of those associated with early epiphyseal widening rather than capping.
If the sesamoid is visible, then either the sesamoid or an SMI based on capping or

<How to product error-free radiographic images for the pediatric patient>
(http://www.dimensionsofdentalhygiene.com/print.aspx?id=3612)
- By Evelyn M. Thomson, BSDH, MS
Panoramic radiographs are often recommended for assessing growth and

development of the pediatric patient and for evaluation of developing third molars
during adolescence.1-3 While the panoramic technique seems relatively straightforward,
producing a diagnostic quality image of the pediatric patient requires a mastery of
technical skill.4 Modern panoramic x-ray equipment is designed for ease of use, yet
studies continue to demonstrate a high incidence of errors.5-7 Positioning errors may
occur at an even higher rate in pediatric panoramic radiographs.7 The goal of the
dental hygienist is to maximize the use of panoramic imagery in the assessment of the
pediatric patient while minimizing the occurrence of retakes that result from the
radiographic error.
Producing A Quality Panoramic Image
A quality panoramic radiograph should image all the teeth, erupted and unerupted, in
both the maxillary and mandibular arches from condyle to condyle in the horizontal
dimension, and from the superior third of the orbit in the superior region to the inferior
border of the mandible in the inferior region.8,9 The arches should appear straight or
slightly U-shaped with the occlusal plane parallel to the horizontal edges of the film
(Figure 1). The anterior teeth must not be magnified or diminished in size and
overlapping of adjacent posterior teeth should be kept to a minimum.
The most important component in producing a diagnostically acceptable panoramic

image is the patient positioning. All panoramic x-ray machines have guidelines to
assist with positioning the dental arches within the three dimensions of the focal trough,

14. Appendices
an area where the anatomical structures will be imaged in relative clarity. Most
ENGLISH
panoramic x-ray machines have a bite block to indicate the correct anterior-posterior
position or how far forward or back the patient should be positioned, side positioner
guides for determining the correct lateral alignment, and a chin rest to correctly locate
the superior-inferior dimension or how far up or down the chin should be positioned.4,10
Panoramic x-ray machines are available with a mirror and laser light beam guide that
shines on the patient's face to illustrate various anatomical planes (Figure 2).
Incorrectly positioning the patient in any of these three dimensions will produce unique
and distinct radiographic image errors (Table 1).

14. Appendices
Anterior-Posterior Positioning Error
When the arches are positioned incorrectly in the anterior-posterior direction, distortion
or ghosting of the anterior anatomy occurs. Unerupted teeth in the anterior region may
not be imaged on the radiograph if positioned outside of the focal trough. It is
important to note that an error of only 3 mm to 4 mm in either direction will result in a
significantly compromised image.11 When the arches are positioned too far anterior,
the anterior teeth will appear narrow and diminished in size. The vertebrae of the
spinal column may be superimposed over the condyles at the edges of the film and,
depending on the size of the child, may be superimposed over the rami of the
mandible blocking a clear view of the posterior teeth (Figure 3). When the arches are
positioned too far posteriorly, the anterior teeth will appear broad or widened. If the
position is excessively posterior, anterior teeth may be completely blurred from the
image and the condyles may be cut off from the edges of the film.
To avoid these imaging errors, the anterior teeth must occlude edge-to-edge onto the
designated area of the bite block. Achieving this position is easily compromised during
exfoliation of primary teeth, making precise occlusion difficult when one tooth or
multiple teeth are missing or partially erupted. A cotton roll may be attached to the bite
block to fill in the space created by the missing tooth or teeth. Additionally, an
adjustment may be necessary when using a laser light beam guide. The
manufacturer's instructions for directing the laser light beam at a predetermined tooth
or interproximal space usually apply to adult patients. These instructions may need to
be modified for the pediatric patient with primary or mixed dentition.

14. Appendices
Lateral Left-Right Positioning Error
ENGLISH
When the arches are positioned incorrectly in the lateral left-right dimension, the
posterior teeth on one side will appear broad or widened, while the teeth on the other
side will appear narrowed or diminished in width and severely overlapped (Figure 4).
This image distortion is like that which occurs with an incorrect anterior-posterior
position. When the arches are rotated or tilted, the posterior teeth on one side move
out of the focal trough to a position further away (back) from the image receptor, while
the opposite side simultaneously moves closer (forward) to the image receptor.
Depending on the severity of rotation or tilting, the inferior border of the mandible will
appear distorted and the condyles and rami will appear asymmetrical.
To avoid imaging errors that result from incorrect lateral positioning, the midsagittal
plane must be positioned perpendicular to the floor. Most panoramic x-ray machines
have a head positioner and/or laser light beam guide, along with a mirror, to assist in
determining the correct lateral head position. The pediatric patient may need additional
instructions to maintain the correct position throughout the exposure.
Movement of the tube head during exposure may pique the pediatric patient's curiosity,
causing the head to rotate as the eyes follow the movement of the tube head. A
vertical line decal affixed to the mirror can serve as a visual aid and a focus point. An
eye-catching sticker, such as those purchased from a craft store, can be adhered to
the mirror in a position that aligns with the midsagittal plane. The patient can be
directed to position the head so that the sticker appears at the tip of the nose and to
maintain focus on this reflection throughout the exposure. Pediatric patients may find
looking at themselves in the mirror entertaining and a fun way to participate in the
process.9

14. Appendices
Superior-Inferior (Up-Down) Positioning Error
Positioning the dental arches within the superior-inferior (up-down) dimension of the
focal trough can be difficult to achieve, especially with children whose smaller size
reduces the distance between the shoulders and the inferior border of the chin. When
the arches are positioned incorrectly in the superior-inferior direction, the image
exhibits multiple distortions, including increased overlapping in the premolar regions.
When the arches are positioned too far up or down, the teeth will simultaneously move
into a position that is too far back or too far forward, respectively, out of the focal
trough.11
Positioning the arches too far superiorly produces a characteristic "frown" or flat,
downward- turned appearance to the occlusal plane (Figure 5). The condyles flare out
and off the edges of the image and the palate appears as a widened, thick, dense
radiopacity. This positioning error results in a widened appearance of the palate and
obliterates the apical regions of the maxillary teeth, compromising the images of the
unerupted developing dentition. As the maxillary arch tips upward, the anterior teeth tilt
backward producing the same widened appearance that results from an incorrect
anterior-posterior position. Positioning the arches too far inferior produces a
characteristic "smile" appearance or upward curve of the occlusal plane, with the
condyles tilting inward toward the center of the image (Figure 6). Depending on the
severity of the downward position, the vertebrae may also curve inward and appear
superimposed over the condyles, and the hyoid bone may be superimposed over the
mandible blocking a clear view of the erupted and unerupted mandibular teeth.

14. Appendices
ENGLISH
Correct positioning of the arches in the superior-inferior dimension requires that the
patient stands with erect posture while tucking the chin in and down slightly, a direction
that both adults and pediatric patients often find difficult to follow without specific
guidance. The result is often a slumped position with the patient hunching the neck
and shoulders over to place the chin on the chin rest. The vertebrae collapse causing
attenuation of the x-ray beam that produces a triangular radiopacity superimposed
over the mandible, and if severe, over the maxillary anterior regions as well.
Depending on the manufacturer, panoramic x-ray machines direct the operator to

position the Frankfort or the canthomeatal plane parallel to the floor, or the ala-tragus
line 5° down toward the floor. This is achieved by raising or lowering the chin rest so
that the appropriate landmark lines up with indicators on the machine (Figure 2). The
patient should be directed to stand in front of the panoramic x-ray machine allowing
the operator to place the chin rest into a position that is slightly higher than the
patient's chin. The patient is then requested to move into the overhead assembly of
the machine and remain standing tall. If further adjustment is needed, it is usually to a
lowered chin position. Once the patient's chin is resting on the chin rest, it is easier to
move to a lower position than to a higher one. To assist with placing the chin on the
chin rest while maintaining an erect posture, the pediatric patient can be directed to
stand like a soldier. Most children are familiar with the straight back, chest forward
tucked chin position demonstrated by military persons, and can readily mimic this
stance.
Further Recommendations
Prior to beginning the exposure, the patient should be directed to close the lips around
the bite block and to place the tongue against the palate. Leaving the lips open will
create a soft tissue shadow across the teeth that that can be mistaken for caries.7
Leaving the tongue at rest during the exposure allows the radiation to easily penetrate
the empty space of the oral cavity between the dorsal surface of the tongue and the

14. Appendices
palate, producing a radiolucent shadow that diminishes the diagnostic quality of the
radiograph (Figure 3).
"Filling in" this space with the soft tissue of the tongue can increase the quality of the
image by diminishing this radiolucent shadow. When directed to place the tongue on
the roof of the mouth, the pediatric patient is likely to press only the tip of the tongue
against the palate. While an adult patient can usually understand what is required
when directed to swallow and note the position of the tongue, a child may be directed
to suck in the cheeks, which results in pushing the tongue into a position flat against
the palate.7
Conclusion
In addition to these guidelines for producing error-free radiographic images for the
pediatric patient, panoramic machines should be evaluated periodically for accuracy.
Changes may occur over time to the focal trough that interferes with the diagnostic
quality of the machine.6 If a decrease in image quality is noted despite following
accurate patient positioning steps, the panoramic x-ray machine should be inspected,
and the focal trough recalibrated. The dental hygienist who is skilled in understanding
panoramic equipment operation and pediatric patient management is more likely to
produce radiographic images that result in higher diagnostic yields.

Pediatric Dentistry 1/2003 Guidelines in dental radiology is 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 benefit. 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 sufficient information to be justified considering the balance between cost
(radiation and resources) and benefit.
