Periodontists and Periodontics 101, Dental Specialties
Periodontics is one of the eight dental specialties recognized by the American Dental Association. Periodontists specialize in Periodontal work. Periodontal comes from two Greek words that mean "around the tooth." The periodontium refers to the anatomical structures around teeth: the gum, bone, and the periodontal ligament that attaches the tooth to the bone.
Periodontists are dentists that have three additional years of training to specialize in the prevention, diagnosis, and treatment of the diseases that affect the gums and supporting structures of the teeth. Periodontists also are experts in the placement and treatment of dental implants.
Periodontal disease is the major cause of tooth loss in adults. According to the American Dental Association, three out of four Americans over age 35 have some form of periodontal disease. Gingivitis is the mildest form of periodontal disease and the most common infection in the world. But if left untreated, it can progress to periodontitis -- the loss of bone and tissues that support the teeth.
Periodontal diseases can be localized to a few teeth or generalized, in which most of the teeth are affected. It can affect people of all ages and without proper periodontal treatment, this disease can result in tooth loss and even complications of systemic diseases.
There are several different forms of periodontal disease. Each can progress at different rates. The same disease can have periods when it develops slowly and others when it progresses quite rapidly. Most of the time, periodontal diseases are painless. But they may have acute episodes that result in severe pain and a dental emergency.
The rate of periodontal disease progression is dependent on a multitude of factors, including the presence of certain risk factors that make people more susceptible to periodontal breakdown.
All periodontal disease is caused by an accumulation of bacteria at and below the gum line. The bacteria release toxic substances that trigger the breakdown of the gum and bone. The gums become red, swollen, and bleed easily. The gum tissue then separates from the teeth, forming a gap called a periodontal pocket or exposing the root surface in what is called recession.
The body responds to the bacteria with an inflammatory response in which it essentially 'turns on itself' and destructs the bone and tissues around the teeth. This is the body's way of warding off infectious agents. The teeth can start moving and shifting and eventually if there is advanced bone loss, the teeth can be lost.
Periodontal diseases are treated in three phases by periodontists. The first is to stop the disease activity and progression of bone loss. In the early stages of periodontal disease, scaling and root planning may be the only treatment needed.
The bacterial deposits (plaque and tartar) that formed above and underneath the gums need to be removed and the root surfaces of the teeth smoothed to enhance healing and deter future plaque retention. During this phase of treatment, the periodontist will review the oral hygiene technique, and give advice on the modification of certain risk factors associated with periodontal disease.
If the periodontal disease is more advanced, surgical treatment may be indicated. The purpose of this phase of treatment is to create an environment that is more amenable to health and, if possible, regenerate some of the bone that was lost to the disease.
In some forms of periodontitis, antibiotic treatment may be indicated. If this is the case, a bacterial culture may be required to test for harmful bacteria and to establish what antibiotics they are susceptible to.
Periodontal disease is a chronic disease that, like many other chronic diseases, has to be closely monitored, even after active treatment. The maintenance or third phase is crucial to the success of any treatment.
Daily brushing and flossing is essential in controlling the ever-developing plaque. So is periodic periodontal maintenance care with a Periodontists scaling of the teeth. The periodontal status has to be closely monitored so that changes can be identified and treated as early as possible.
Everyone should be routinely screened for periodontal disease. All periodontists are qualified in detecting and treating the early stages of periodontal disease, but if you suspect that you are at risk, or you know you have periodontal disease, you may want to see a periodontist who has extensive advanced training in the diagnoses and treatment of periodontal diseases.
With today's Periodontists knowledge about periodontal diseases and the new advances in treatment, you can expect to keep your teeth for a lifetime and ward off the effects that periodontal disease may have on your overall health.

Periodontal Disease: Preventing Tooth And Bone Loss
The best way to control periodontal disease and to help prevent tooth loss is with early detection and treatment. Three out of four people are afflicted by periodontal disease at some point in their lives, so everyone should be tested. After reviewing a patient's dental and medical history, the dental care provider or periodontist will conduct a thorough clinical intraoral exam called a periodontal charting.
This consists of taking a series of measurements around each tooth. Unless the gums are very inflamed and sensitive, the periodontal charting causes minimal discomfort.
The space between the gum and the tooth is measured using a periodontal probe. This space is called the probing or pocket depth. In a healthy mouth, this space should be between 0 and 3 millimeters.
The amount of recession or loss of gum around each tooth is measured. In healthy mouths, the gum tissue should be at the junction of where the crown of the tooth meets the root. The two measurements (pocket depth and recession) are then added to calculate the amount of attachment loss around each tooth. The greater the amount of attachment loss, the more advanced the periodontal disease.
While completing the periodontal charting, a dentist will evaluate the conditions of an individual's gums. Healthy gums are pale pink, firm, and immobile. The gums should not bleed during the probing exam. Bleeding gums during this exam are a sign of gum inflammation, gingivitis or periodontitis.
The dentist will also measure tooth mobility. Under normal functional conditions, teeth should not move. Tooth mobility is a sign that there has been bone loss around the teeth or that the biting forces are too strong. If so, the dentist may also assess a patient's occlusion, or bite. If the bite has changed or if the forces on the teeth are too strong, there may be an acceleration of bone loss around the teeth.
A full mouth series of X-rays (approximately 20 films) are also indispensable in a periodontal examination.
In addition to identifying areas with cavities, bone infection, tumors, or developmental abnormalities, X-rays help reveal if bone loss has resulted from periodontal disease. The crest of the teeth's supporting bone is normally 2 mm below where the crown of the tooth meets the root. A greater distance indicates a history of bone loss.
Although bacterial samples are not usually taken for diagnosis of periodontal disease , under certain circumstances, it may be necessary to take a bacterial culture from a plaque sample. This is especially valuable to help detect sites at high risk for disease progression or if conventional treatment is not working.
The culture is analyzed in a laboratory for the presence of certain bacteria that are known to contribute to gum disease. Actually, of the more than 300 different types of bacteria normally found in the mouth, there are only about 13 that are known to be associated with causing periodontal disease. After identifying the specific disease-causing bacteria, the laboratory can test to determine what antibiotics they are susceptible to.
Depending on the risk factors (see article " Risk Factors for Periodontal Disease") involved and a person's specific situation, other tests may also be required. Under certain circumstances, a dentist may require diagnostic casts (molds of one's teeth), medical laboratory tests, medical consultation, or genetic testing.
After completing the periodontal examination, the dentist will be able to discuss with the patient the diagnosis, treatment alternatives, potential complications, and expected results. The key to long-term periodontal health is early diagnosis and treatment. Because everyone is at risk of developing periodontitis, everyone should be routinely tested.
