Gingival Recession Coverage With and Without Emdogain

Enamel matrix proteins have been shown to play a crucial role during tooth development and its supporting tissues. This is used in periodontal surgery where regeneration of lost tissues around the teeth is intended. Emdogain, a product of Straumann Institute contains these matrix proteins and has been successfully used in regenerative periodontal surgery for more than 16 years. The treatment of gum recession is a common requirement, more and more patients are seeking treatment at the investigators' clinic due to aesthetic concern, root sensitivity and difficulties in performing adequate oral hygiene. The standard treatment comprises the transplantation of a piece of connective tissue from the palate to the denuded root surface. In many cases Emdogain is additionally applied to enhance healing. So far the effect of Emdogain on the early wound healing process after surgical root coverage has not been investigated. The purpose of the investigators' study is to compare early wound healing parameters between treatment with and without Emdogain. For this study 40 patients undergoing root coverage surgery at the investigators' department will be included. Early wound healing features between the two groups will be described and compared. Furthermore, inflammatory markers typical for early healing will be evaluated together with patients'subjective postoperative comfort. Finally, outcomes 6 months after the treatment will be assessed. The investigators' hypothesis is that Emdogain treatment enhances wound healing and decreases post-operative complication rates.
