Not illustrated. 1919 Excerpt: ... be noted are: --(1) That there is no'well-defined line between the cavity and tie surrounding bone, such as is noticeable in skiagrams of cysts. (2) That there is indication of bone posterior to the roots. The morbid anatomy of palatal abscesses is shown in fig. 633. The pulp of the left central incisor has been exposed by attrition, an abscess has formed around the apex of the root and has then made its way through the outer alveolar plate. The lateral incisor which shows marked attrition has been attacked by caries and the suppuration of the pulp has been followed by infection of the bone. The destruction of the bone has laid bare the whole of the root Fig. 633.--Side view of a specimen showing bone destruction in connection with a lateral incisor. of the incisors and the upper aspect of the mesial surface of the canine root. Extending backwards, the abscess has at one place completely destroyed the bone forming the palatal surface, so that one opening exists near the anterior palatine foramen. In its forward extension the abscess has opened into the cavity previously formed around the central incisor and by this means there is a free communication through the outer alveolar plate. The skiagram of this specimen is seen in fig. 634. This type of case would present the well-recognized clinical features of a palatal abscess. There would be a swelling in the palate, with a bulging of the tissues over the anterior aspect of the tooth and definite fluctuation between the two surfaces. A dento-alveolar abscess in connection with the maxillary canine usually opens through the anterior alveolar plate about the region of the apex of the tooth. More rarely the pus will track towards the nasal fossa and, discharging into that cavity, give rise to a Fig. 634.--Skiagra..
