Periodontal Regeneration Dentistry Treatment
Periodontal regeneration means restoring the bone and supporting tissues adjacent to teeth with advanced bone loss. Frequently, periodontal regeneration treatment will prolong the use of the involved teeth. A periodontist or dentist will diagnose the problem by taking a careful medical and dental history.
The tissues adjacent to the teeth will be gently probed with a calibrated, ruler-like instrument. These measurements, together with a dental X-ray, will help determine the appropriate treatment for the involved teeth.
There are many regenerative techniques and methods. Bone purchased from bone banks has been used effectively as a regenerative material for over 30 years. This bone is procured from healthy individuals, is carefully processed, and has been proven safe. Treatment consists of carefully moving the gum tissue away from the involved teeth and removing tarter (calculus) deposits from the root surfaces.
The bony defect is gently filled with the bone bank material (allogenic bone) or other synthetic materials. The gums are then replaced around the neck of the teeth with small sutures. The sutures are removed within five to seven days, and gentle tooth brushing can resume.
Synthetic bone substitutes have been developed to simulate natural bone. These materials are safe, and may help support the involved teeth. Such substitutes are implanted through periodontal surgery. Recently, cow bone, which is carefully prepared, sterilized, and safe, has been used to repair defects next to teeth. This bone is porous, allowing bone from the patient to grow into the pores. New technologies have developed porcine (pig) proteins, which, when painted onto teeth, allow for natural regeneration of tooth cementum and bone. These materials have demonstrated early promising clinical results.
The use of barrier membranes to protect and isolate bony defects has been used for over 15 years. These are made from synthetic, non-dissolvable materials, dissolvable materials, or bovine collagen (cow collagen). Membranes are frequently used either with synthetic graft materials or with bone purchased from bone banks. Recently, proteins have been joined to synthetic bone.
This material enhances cell attachment to root surfaces and may provide an effective method for periodontal regeneration. In the future, proteins that stimulate bone formation and enhance formation of new root cementum will make periodontal regeneration a simple, effective method to save teeth with advanced disease.
The materials discussed above have been published in dental journals, are safe, and generally result in tooth retention with bone fill of the treated bony defects. Articles relating to periodontal regeneration can be researched from PubMed using the following key words: "periodontal," "regeneration," "allogenic bone," "synthetic bone grafting," and "barrier membranes."

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.
