Periodontal disease

Description

An in-depth report on the causes, diagnosis, treatment, and prevention of periodontal disease.

Alternative Names

Gingivitis

Other Treatments

Nonsteroidal Anti-inflammatory Drugs (NSAIDs). NSAIDs are drugs that block factors that cause inflammation and pain.

• Over-the-counter NSAIDs include aspirin, ibuprofen (Motrin IB, Advil, Nuprin, Rufen), naproxen (Aleve), ketoprofen (Actron, Orudis KT).
• Prescription NSAIDs include naproxen (Naprosyn, Anaprox), diclofenac (Voltaren), tolmetin (Tolectin), ketoprofen (Orudis, Oruvail), indomethacin (Indocin).

These drugs are used not only for relieving pain in periodontal disease but also for slowing the disease process. NSAIDs block inflammatory enzymes triggered by cytokines, which are important immune factors in periodontal disease. A number of NSAIDs have been investigated and have been shown to reduce gingivitis and slow progression of periodontal disease.

In one study, long-term use of oral flurbiprofen (Ansaid) resulted in significantly lower bone loss, although disease progression returned when the drug was stopped.

Investigators are also studying rinses, creams, and other topical forms of NSAIDs. For example, a cream containing ketoprofen appears to reduce bone loss. (Ketoprofen is of particular interest because it blocks not only COX-2 but also another pathway involved in the disease process.)

Warning about NSAIDs: Although NSAIDs work well, long-term use can cause stomach problems, such as ulcers and bleeding, and possible heart problems. In April 2005, the FDA asked drug manufacturers of NSAIDs to include a warning label on their product that alerts users of an increased risk for cardiovascular events and gastrointestinal bleeding.

Growth Factors

Gels containing growth factors -- including substances called recombinant human (rh), platelet-derived growth factor-BB (PDGF-BB), and (rh) insulin-like growth factor-I (IGF-I) -- are showing promise for restoring bone.

Vaccines

Research is underway to find a vaccine against periodontal disease. To date, animal studies show promise, but an effective vaccine for people is years away.

Photodynamic Therapy

Researchers are investigating the use of photodynamic therapy (PDT) as an alternative to antibiotic drugs. PDT destroys periodontal bacteria by applying photosensitive drugs to oral regions and exposing the drug-treated area to a light or laser. Research appears promising but is still in its preliminary stages.
