Such lesions con-taining fluid pus, however, are in a considerable minority,as compared to the solid or semisolid granuloma, and,therefore, the term chronic abscess is entirely inap-plicable in the great majority of cases of periapicalinfection. These areas of bone rarefaction and destruction varygreatly in size. The bone absorption is usually accom-panied by a slow detachment and destruction of the peri-dental membrane covering the cementum at the root end, PATHOLOGY AND DENTAL ROENTGENOLOGY 41.
