A
type of dental x-ray machine has been developed that simplifies the dental X-ray
process as a diagnostic tool.
This
X-ray along with bite-wing X-rays give Dr. Peterson and his staff much needed
information about the health of your teeth and gums.
A Panoramic X-ray is very commonly taken on an “initial”
visit.
As
the name suggests a Panoramic X-ray makes a complete half circle from ear to ear
to produce a complete two dimensional representation of all your teeth to give
an overall picture of your teeth and jaw bones.

Where the bite-wing or periapical X-ray film allow us to see small areas
of your mouth; the Panoramic X-ray film allows us to see a “panoramic”
single picture view of your entire oral cavity, all at one time.
This
“panoramic” view of your oral cavity is accomplished by rotating the X-ray
film around your head for about 12 seconds.
It is important that you remain as still as possible during these 12
seconds to obtain a total angle view for a high quality picture.
You will be
positioned erect between the x-ray source and the film. Correct position of the
head is very important for a good picture.
Panoramic
radiographs (PMX)s may provide information about systemic
health conditions**

This Panoramic X-ray is especially effective in the
following areas:
1. Fractures of the teeth and/or jaws can be seen when it is difficult to
open your mouth
2. Viewing development, position, and
eruption of primary teeth so we can
see all your child’s baby teeth and permanent teeth
at one time
3.
For individuals who have difficulty holding x-ray films in their mouth
4. Diagnosing Temporomandibular Joint (Jaw hinge) dysfunction
5. Viewing impacted wisdom teeth
6. Detecting presence of bone or gum diseases
7. Diagnosing early signs of oral cancer
8. Discovering nonmalignant tumors
9. Surveying the sinus region
10.
Discovering stones in the salivary glands
11.
Examining trauma patients
12.Screening for stroke,
osteitis deformans, hyperparathyroidism and other systemic diseases.
13.Obtaining baseline data for long term dental health
14.
Diagnostic data for referring dentist to use
15.
Critical for setting broken facial bones
16.
Identification in case of an accident
17. Provide valuable information about
signs of carotid calcification. Alveolar bone loss as assessed
from PMXs is associated with cardiovascular
diseases.**
18. Evaluation for full or partial removable
dentures, dental implants, or braces.
19. Alternative for those who can
not tolerate other types of films, gaggers.
20. New patients to help screen for
diseases beyond just the teeth.
21. Screening for osteoporosis
postmenopausal women may lose as much as 20% of their bone mass
within
5-7 years postmenopause. 1 in 4 men have osteoporosis
after the age of 50. 55% of people over 50 have
osteoporosis.
22. Metastases to jaws. Carcinomas
of the brest, lung, prostate, thyroid glad, kidney, and colon
may produce cyst-like growth.
23. Genetic abnormalities.
24. Developmental
abnormalities-cleft palate.
25 Asymmetry of the Oral and
Maxillofacial area which could be caused by swelling on one side
of the face such as seen in
eating disorders.
26. Altered nerve sensation-paresthesia
in lip, or hypersensitivity which could be caused by
infectious osteomyelitis or a malignancy compressing a
nerve.
27. Pain-find cause and location of
pain.
28. Ill fitting dentures- due to
alveolar bone loss.

Radiographic
Measures of Chronic Periodontitis and Carotid Artery Plaque
Chronic periodontitis (CP) is associated
with stroke and subclinical atherosclerosis, but clinical
measurement of CP can be time consuming and invasive. The
purpose of this study wasto determine whether radiographically
assessed CP is associated with nonstenotic carotid artery plaque
as an ultrasound measure of subclinical atherosclerosis.
Panoramic oral radiographs were obtained from 203 stroke-
free subjects ages 54 to 94 during the baseline examination
Severe periodontal bone loss is associated independently with
carotid atherosclerosis. Panoramic oral radiographs may thus
provide an efficient means to assess CP in studies of
atherosclerosis risk.
