Schematic diagrams of several techniques commonly used in periodontal surgery. (A) OFD procedure
involves the periodontal surgeon lifting the gum away from the tooth and surrounding bone, providing
increased access for scaling and root planning. However, periodontal defects, if left empty after OFD, fill with
the first cells to reach the area, i.e., epithelial cells (1) and fibroblasts (2), after cell proliferation, which
generates core of fibro-epithelial tissues that attach to the root surface, hence bone (3) and periodontal
