Regenerative Periodontal Surgery using Enamel Matrix Derivative and Biodegradable Barriers

Abstract

The overall aun of regenerative treatment is to re-establish the true functional attachment of the diseased tooth by building new acellular cementum, periodontal ligament and alveolar bone. For many years, periodontal regeneration has been viewed as an ultimate goal, unfortunately this goal is still quite difficult to obtain. In recent years a number of special treatment procedures have been introduced to promote regeneration of lost periodontal tissues. These include different modalities of "' flap procedures often combined with implantation of bone grafts of various types of bone substitutes, demineralization of the root surface, guided tissue regeneration and combinations of these modalities. However, it is only recently that there has been some concordance between theory and clinical practice by the advent of, for example, the guided tissue regeneration technology and research into the use of naturally occurring biological substances. The present study compared . the clinical and radiographic results of treatment of deep intrabony periodontal defects using enamel matrix derivative to the results obtained by using biodegradable barriers in patients suffering from aggressive periodontitis. 32 defects in 10 patients (both males and females) were selected from the Outpatient Clinic, Department of Oral Medicine and Periodontology, Faculty of Oral and Dental Medicine, Cairo University. The patients were suffering from aggressive periodontitis. Each patient exhibited at least one pair of similar periodontal defects (interproximal intrabony lesions).
