Bovine collagen could be used to promote the healing of gums, a new study has indicated.
Research published in journal Head & Face Medicine revealed that the substance could be used to treat patients with receding gums.
Using the collagen matrix was observed to lead to thicker margins around the tooth and in over half of cases, complete coverage of exposed roots.
Scientists extracted the collagen from bovine pericardium using osmotic, oxidative and alkaline treatment.
They treated 14 patients, cleaning the damaged teeth before surgery and holding the collagen implants in place with loops of surgical thread. After two weeks the sutures were removed, and the patients were examined again after six months.
Dentist Dr Markus Schlee reported: "In all cases the healed-over implant improved the look and severity of the recession, and, in over half of all treatments, resulted in total coverage of the exposed root. We would not have expected any of these patients to get better without surgery."
