Reactional inflammatory bone diseases are common in the jaws and are associated with periapical lesions. A chronic dentoalveolar abscess represents a chronic purulent osteitis, just like periapical granuloma is a chronic granulomatous osteitis. Imagiologically, chronic inflammatory periapical injuries are osteitis which manifest themselves either as bone rarefactions, either as sclerotic areas. The terms “rarefying diffuse lesion” or “sclerosing at the periapex” are used in reports to identify chronic inflammatory periapical lesions that represent true reactive inflammatory bone diseases with specific names by the direct relationship with the teeth as dentoalveolar abscess and periapical granulomas. When teeth are extracted they can leave imagiologically detected structural changes, such as bone sclerosis and rarefactions, without the possibility of establishing a cause and effect relationship, making it hard to provide a secure diagnosis. In planning, a previous diagnosis of bone status implies recognizing injuries and pathological situations. The standardization of nomenclature and concepts can facilitate communication and the establishment of uniform protocols and behaviors.
