Periodontal Disease Treatment Slows Periodontitis
One of the goals of periodontal disease treatment is to arrest and control the progression of the bacteria that cause gingivitis and periodontal disease. As the bacteria infect the gum tissues, they release toxic substances that trigger the breakdown of gum and bone. The gum then separates from the teeth, forming a gap that is called a periodontal pocket. These spaces are inaccessible to daily oral hygiene techniques. Bacteria settle in these pockets and continue to accumulate and reproduce, creating further gum and bone destruction.
Periodontal disease treatment such as scaling and root planing involve the removal of the irritants and bacterial deposits (plaque and tartar) that have accumulated above and below the gum line in the periodontal pockets. The root surfaces of the teeth are planed (smoothed) to promote healing and to help prevent future bacterial reattachment. At the same time, gingival (gum) curettage can be done to remove the infected soft tissues that line the periodontal pockets.
Most of the time, scaling and root planing is done in two to four visits. For patient comfort, the gums can be numbed by the periodontist using a local anesthetic. One-quarter of the mouth is usually treated at the time and treatment of each quarter can take 45 minutes to an hour (three to four hours for the entire mouth). Most patients report minimal discomfort during these periodontics treatments.
During scaling and root planing appointments, the dental care provider will review oral hygiene techniques that are aimed at improving the person's ability to control plaque and to help avoid bacteria from re-infecting the pockets. Patients also will receive advice on the modification of certain risk factors associated with periodontal disease.
In some circumstances, the dental care provider may recommend the use of adjunctive products for periodontal treatment. To be effective, antimicrobial products such as Chlorhexedine, PerioChip, and Atridox should be used in combination with scaling and root planing. Periostat is also a product that can be used as an adjunct to scaling and root planing in order to impede further tissue breakdown and promote healing.
Several weeks after completion of scaling and root planing, a periodontal re-evaluation should be completed. The purpose of this exam is to assess the response to treatment and determine if there is a need for further treatment.
The best way to stop the progression of periodontal disease is to mechanically remove the bacterial plaque and tartar that have accumulated in the periodontal pocket. Daily oral hygiene and supportive periodontal treatment (see article "Supportive Periodontal Treatment") is key to the success of scaling and root planing. Without treatment, the tartar and plaque buildup underneath the gums will continue to cause periodontal tissue breakdown, progression of periodontal disease, and eventually tooth loss and/or systemic (general) complications.

Periodontics: Uses of Periodontic Dental Lasers
Since their introduction in the 1960's, laser use in medicine and dentistry has increased steadily, and it's been no different in Periodontics. The CO2 and the Nd:YAG lasers have both received Food and Drug Administration (FDA) approval for soft tissue surgery and are the most commonly used lasers in dentistry. A dental laser work by delivering concentrated beams of light strong enough to cut through tissue.
Pros & Cons of Dental Lasers
The popularity of lasers results from claims that dental laser gum treatment is painless. Although the FDA has not permitted the manufacturer of any laser to make that claim, the general experience described by patients is that there is less pain and swelling after laser treatment compared to conventional oral surgery. Local anesthesia for pain control is still required during laser surgery.
Another advantage of the laser is that it causes less bleeding in the area of surgery than traditional oral surgery techniques. This is especially helpful in the oral cavity, which has an abundant blood supply. The laser decreases bleeding by sealing the blood vessels at the surgical wound. On the flip side, this can delay healing and create a less stable wound.
Application of Lasers in Periodontal Treatment
The application of lasers in periodontal treatment is restricted to the removal of gum tissue to reduce pocket depth, or for some minor periodontal plastic surgery procedures. These surgeries can be easily performed with traditional instruments without the additional high cost of dental laser treatment.
More recently, lasers have been evaluated for use in scaling and root planing. But in a research study recently published in the Journal of Periodontology, laser therapy appeared to be less effective than traditional scaling and root planing treatment. In fact, research has not conclusively shown that laser therapy is effective in removing the tartar that has accumulated under the gum line and can actually damage the surfaces of teeth and the bone. This damage could delay healing and the ability of the gum tissue to reattach to the root surface.
For all these reasons, the American Academy of Periodontology is concerned about misleading claims regarding the use of lasers in periodontics. It is important to remember that laser treatment in periodontics is limited to soft tissue (gum) for periodontal surgery and that the laser beam should not touch the tooth or bone. Anesthesia is required during dental laser treatment, and dental laser treatment may be more expensive than traditional surgical procedures.
