fibrous than its inner portion,there is no limiting membrane in the sense of preventingits contents from entering the general circulation. After eradication of infection in a periapical bone area,new bone is usually formed, filling in the space after sev-eral months. The space at first contains blood clot, which,if sterile, organizes into fibrous connective tissue. Thenthe bone cells of the surrounding alveolar process depositlime salts, the density gradually increasing until normalbone is the result. Occasionally this new bone is muchdenser than normal, due to excessive deposit of limesalts, and is shown in the odontogram as a light area.This dense bone, by pressure on sensory nerve filaments,may cause neuralgia. Cyst Formation Among the connective tissue elements of the inflamma-tory granuloma developing as a result of infection aboutthe root apex are frequently found masses of squamousepithelial cells (Fig. 17). Similar cells are present nor- PATHOLOGY AND. DENTAL ROENTGENOLOGY 43
