Use of Emdogain in the treatment of deep intrabony defects: 12-month clinical results. Histologic and radiographic evaluation.

The objective of this study was to evaluate the application of an enamel matrix derivative (Emdogain) in deep periodontal pocket therapy. Twenty-one patients presenting intrabony and interproximal defects that could be treated with guided tissue regeneration were selected. The intrabony defects were divided into deep (< 9 mm) and very deep (> or = 9 mm) defects.
