Receding gums are repairable with a gel that uses platelets to restore gum tissue over teeth.

Traditional gum grafting surgery requires surgically excising tissue from the roof of the mouth (the palate) to replace the gum tissue lost around the teeth. Unfortunately, removing tissue from the roof of the mouth extends recovery time and is a major source of patients’ discomfort or pain. According to the American Academy of Periodontology, periodontal disease is the primary cause of tooth loss in adults aged 35 and older. Periodontal disease includes gum recession, also called gingival recession, which can result in tooth root decay and tooth loss.

 

The new tissue regeneration application from Tufts uses platelet concentrate gel applied to a collagen membrane as the graft instead of using tissue from the roof of the mouth. The graft is soaked in the patient’s platelets, using blood drawn in the same visit. Placed over the receding tooth root, the graft is then surgically secured.

 

In order to examine three-year efficacy of the treatment, measurements were taken from six patients in the gum recession area at baseline, 6, and 36 months after surgery. At six months, 24 out of 37 teeth from the six patients had complete root coverage (65 percent). At 36 months, 21 out of 37 teeth from the six patients had complete root coverage (57 percent). The authors said that the recession over three years was minimal and that the results are comparable to traditional gum grafting surgery.

We need methods for engineering tissue to get it to grow where we want and to become the types of tissue we need for repair. Success stories like the one above demonstrate that guided tissue growth isn't only in our distant science fiction future. It is in our short term future as well.
