Genetics and gum disease
According to an article in Medical News today the University of Michigan Dental school is to conduct a large study using genetic testing to assess the risk of gum disease.
The study will have access to patient clinical outcomes of an insurance company and they will recruit at least 4,000 patients. Genetic testing along with clinical information will be used to work out who needs more frequent treatments and who needs less. Smoking and diabetes will also be taken into account as major periodontal risk factors.
The genetic testing company is hoping that the information obtained will be significant enough that genetic testing becomes a routines part of dental diagnosis.

What is gingivitis?
Gingivitis is inflammation of the gingivae (gums).
What is periodontal disease or gum disease?
Gum disease (also called periodontal disease) is an infection of the tissues
surrounding and supporting the teeth. Gum disease is a major cause of tooth
loss in adults. Because it is usually painless many people do are not aware that they have gum disease. In the general population of Australia about 10% have advanced or severe gum disease, 80% have mild to moderate disease and 10 % have no gum disease.
What
causes gum disease?
Gum disease is caused by plaque, a sticky film of bacteria that constantly
forms on the teeth. Bacteria creates toxins that both damage the gums and result in a reaction by the body which results in loss of bone and supporting tissue of the teeth.
Gum disease is still subject to intense research. Scientists are looking at ways to kill off the offending bacteria and how to make the bodies reactions to the toxins less severe.
Treating gingivitis
- Remove the cause - clean your teeth well. Use a toothbrush and floss
- For acute infections sometimes dentists will recommend chlorhexidine mouthwash or an antibiotic.
- As per treating gingivitis - effective removal of plaque
- Any defective restorations or those that trap plaque may need to be changed so you CAN clean.
- Removal of calculus (hardened plaque)
- Scale and cleaning
- Root planning
How do I know if I have gum disease?
- Bleeding or swollen gums
- Changes in the color of the gums
- Bad breath
- You might not be able to tell! It can be very slow or may cause you no obvious complaints.
- Dentists can tell from "Probing" your gums
- 'X-rays' will show loss of bone which indicates periodontal disease. Calculus that causes periodontal disease may also be seen in x-rays
Bleeding
gums
MYTH: Bleed gums are caused by brushing.
Bleeding gums are not normal and the cause should be investigated by a dentist.
Bleeding is an early sign of periodontitis but may not result in any further
problems. However, it is usually also present where the disease has started
to cause loss of bone around the teeth, with development of "pockets" where
the gum becomes detached from the tooth and areas of plaque and food accumulation
occur, which in turn cause further problems.
Other conditions can cause bleeding gums.
What
is plaque?
Plaque is a build up of bacteria and other microorganisms, dead cells, and a
bit of left over food. Scrape your fingernail over your tooth and the whitish
film that you collect is plaque.
The inside of the mouth is a cosmopolitan village of bacteria and other microorganisms
that we can't permanently remove. Experiments have shown that one hour after
cleaning up to one million bacteria can be recovered from a tooth surface! A diet of refined foods tends to result in a greater build up of less desirable
bacteria on the teeth.
What is tartar/calculus?
Calculus is something studied in higher mathematics
and tartar is something said by babies when they wave good-bye! No. Try again.
Calculus (or tartar) is plaque which has been hardened
by minerals. The amount of calculus that forms around the teeth is determined
by the cleanliness of the teeth and the amount and types of minerals in
the saliva and being released around the teeth.
Periodontal pockets
A periodontal pocket isthe gap measured between the tooth-gum edge and the underlying bone. A pocket can be difficult to clean and is a home to bacteria and other microorganisms.This can cause bad breath. Dentists use a periodontal probe to tell if a periodontal pocket is present.
Periodontal probing
A periodontal probe is used to measure the bone loss around
teeth and to determine whether gums bleed easily. When the probing measurements are recorded this is called periodontal charting. Up to 6 measurements may be recorded for each tooth. This can help a dentist work out if treatment for periodontal disease is effective.These photos show the periodontal probe inserted into a "pocket" to
a depth of 7 mm. In an ideal healthy situation this measurement would be less
than 3 mm
Scaling and cleaning
This involves cleaning the root surface of the tooth to remove plaque
and calculus.
Cleaning calculus is done with sharp instruments called "scalers"
or sometimes with an ultrasonic
cleaner which vibrates off the hardened material.
Root planing
When the calculus and plaque is located on the tooth roots and in deep pockets
its removal and the subsequent cleaning of the root surfaces is sometimes
referred to as "Root planing". The treatment is similar to scaling
and cleaning but usually more difficult and time consuming because it is difficult to get to deep areas.
Periodontal surgery and other forms of treatment
When gums are not healing well after scaling or Root planing other forms
of treatment may be required. Your dental health professional will discuss
these with you.
Smoking and gums
Smoking -Smokers are at between 2.5 and 6 times greater risk of periodontal
disease compared with nonsmokers. This may be because smoking affects
the immune system by lowering the body's ability to inhibit bacteria that
are associated with periodontal disease. To find out more about quitting smoking try the QUIT site
Heart attacks and gums
A lot of recent research has looked at the link between periodontal disease
and heart attacks. Heart attacks have been shown to be related to bacterial
and viral infections and the mouth is now being examined closely as the source
of these microorganisms.
A study* by the school of dentistry in Turkey looked at 120 patients with
heart problems and concluded that periodontal disease may be associated with
acute heart attacks. To

Strokes and gums
Periodontal disease has also been shown to be an important risk factor for
strokes (cerebrovascular accidents) according to a study# published in October
2000 which looked at 9962 adults aged between 25 and 74 years. The lowest
risk people where those with gingivitis, followed by those with no teeth and
those with periodontal disease where at greatest risk. To

The implications of this research are that keeping your teeth and gums healthy
is important to your overall health.
