Q: How often should a child have dental X-ray films?
Since every child is unique, the need for dental X-ray films varies
from child to child. Films are taken only after reviewing your
child’s medical and dental histories and performing a clinical
examination, and only when they are likely to yield information that a
visual examination cannot.
In general, children need X-rays more often than adults. Their mouths
grow and change rapidly. They are more susceptible than adults to
tooth decay. For children with a high risk of tooth decay, the
American Academy of Pediatric Dentistry recommends X-ray examinations
every six months to detect cavities developing between the teeth.
Children with a low risk of tooth decay require X-rays less
frequently.
Q: Why should X-ray films be taken if my child has never had a cavity?
X-ray films detect much more than cavities. For example, X-rays may be
needed to survey erupting teeth, diagnose bone diseases, evaluate the
results of an injury, or plan orthodontic treatment. X-rays allow
dentists to diagnose and treat conditions that cannot be detected
during a clinical examination. If dental problems are found and
treated early, dental care is more comfortable and affordable.
Q: Will X-ray films be taken routinely?
No. X-ray films are recommended only when necessary to evaluate and
monitor your child’s oral health. The frequency of X-ray films is
determined by your child’s individual needs. If your child’s
previous dentist obtained X-ray films, request copies be sent to your
new pediatric dentist to help reduce radiation exposure.
Q: How safe are dental X-rays?
Pediatric dentists are particularly careful to minimize the exposure
of child patients to radiation. With contemporary safeguards, the
amount of radiation received in a dental X-ray examination is
extremely small. In fact, dental X-rays represent a far smaller risk
than undetected and untreated dental problems.
Q: What safeguards are used to protect my child from X-ray exposure?
Lead body aprons and shields help protect your child. Today’s
equipment filters out unnecessary X-rays and restricts the X-ray beam
to the area of interest. High-speed film, digital X-rays, and proper
shielding assure that your child receives a minimal amount of
radiation exposure. |
