[Surgical and nonsurgical therapy: possibilities and limits in treatment of periodontal disease].

Abstract

Authors expose literature about kinds of periodontal lesions recovery achieved by surgical and non-surgical techniques to establish which of them is preferable and when. They emphasize that, by both techniques, recovery occurs through a "long epithelial attachment" and that is very preferable the surgical technique of tissues guided regeneration gained by membranes that allows the formation of a "new attachment".
