It has been suspected for years that gum
disease like other common diseases such as heart disease and diabetes, is influenced
by a combination of your genes and the environment (ex: oral hygiene, smoking, diet).
Today, we not only have evidence of this, but can identify the individuals who have a
genetic tendency to develop gum disease. This is done using modern genetic analysis
and a test called PST.
The good news is that your
PST result is not a verdict, but a tool for you and your Periodontist to use in
determining how best to treat you and prevent the disease from progressing.
Remember, the best way to lower your risk is to modify the habits that contribute to the
disease! Gum disease is both preventable and treatable, but your Periodontist needs
to know your individual genetic and behavioral risk in order to help you avoid problems in
HOW IS THE PST TEST DONE?
PST is performed by
collecting a blood sample from your finger at your Periodontist's office. This
sample contains DNA, which is sent to a licensed medical laboratory. Using modern
genetic analysis, it is determined whether your DNA is PST positive or negative. By
considering your PST result together with other environmental risk factors (smoking, oral
hygiene, diet, etc.) your Periodontist can determine your overall risk profile.
WHO SHOULD CONSIDER THE PST TEST?
Anyone who has early signs of
gum disease, it is important to know the risk for future disease progression. This
will allow for a more targeted and proactive plan base on your history of diease and
future risk. If you are PST positive, you might benefit from seeing a Periodontist, such as Dr. Mao.
