Entire Papilla Preservation Technique with Enamel Matrix Proteins and Allogenic Bone Substitute for the Treatment of Isolated Intrabony Defects: A Prospective Case Series.

The aim of this study was to evaluate the outcomes of a modified entire papilla preservation technique (EPPT) in the treatment of isolated intrabony defects in patients diagnosed with stage III periodontitis. A total of 18 intrabony defects were treated: 4 one-wall, 7 two-wall, and 7 three-wall. Mean probing pocket depth reductions of 4.33 mm ( < .0001), clinical attachment level gains of 4.87 mm ( < .0001), and radiographic defect depth reductions of 4.27 mm ( < .0001) were observed at 6 months. Changes in gingival recession and keratinized tissue were not statistically significant. It can be concluded that the proposed modification of the EPPT is useful in the treatment of isolated intrabony defects.
