After the cleaning procedure, the dentist will check the pocket depths around the teeth after the cleaning process has been completed. Further treatment needs are determined by the results of these initial sessions:

• If the cleaning processes have reduced inflammation, observation only is needed.
• If an abscess is present, surgery is often warranted. (One case study suggested that simply draining an abscess caused by deep pockets and allowing the periodontal pockets to improve and the gum tissue to return to health may avoid the need for surgery. If, in such cases, tissue health has not been achieved, and if the pocket depth is greater than 4 mm, surgery may be necessary.)

Finally, the dental hygienist or practitioner should offer thorough instructions on home care to insure the removal of bacteria on a daily basis. This includes proper use of the toothbrush, paste, mouth rinses, floss, floss threaders, and proxabrushes. Home care can effectively eliminate the plaque above the gums and down to 2 mm below the gums.

Gingival Curettage

Gingival curettage removes the soft tissue lining of the periodontal pockets in order to completely eliminate bacteria and diseased tissue. It may be used along with scaling and root planing, but achieves a deeper and more complete cleaning. Evidence indicates, however, that it does not contribute any additional benefits beyond simple scaling and planing.

Surgery (Open Flap Curettage)

Surgery allows access for deep cleaning of the root surface, removal of diseased tissue, and repositioning and shaping of the bones, gum, and tissues supporting the teeth. Surgical procedures vary depending on the individual diagnosis and needs of the patient. The basic procedure is known as open flap curettage. It involves the following:

• The periodontal surgeon lifts, or flaps, the gums away from the tooth and surrounding bone.
• The diseased root surfaces are cleaned and curetted (scraped) to remove deposits.
• Gum tissue is replaced into positions to minimize pocket depth.
• The periodontist may also contour the remaining bone and attempt to regenerate lost bone and gingival attachment through bone grafts and guided tissue regeneration or the use of enamel matrix protein derivatives.
