25. The basic function of the gingival fiber groups (apparatus) is to maintain the free
gingiva and junctional epithelium in close approximation to the tooth. The gingival
epithelium lamina propria is similar to other tissues of the body (i.e., consists of
fibroblasts, mesenchymal cells, mast cells, and macrophages).

projections of elastic fiber bundles into the papillary layer of the lamina propria,
which elevate the epithelium into rounded prominences that alternate with
indentations of the epithelium.
