Fig. 84. Fig. Fig. 86. 132 ELECTRO-EADIOGRAPHIC DIAGNOSIS Fig. 87. A photograph of a skull showing the anteriorpalatine foramen, also called the incisive foramen. Fig. 88. The large radiolncent area and the short rootof the central incisor would lead the unwary and the non-user of the electric test to suspect that we have here adentoalveolar abscess exhibiting considerable tissue de-struction both osseous and dental. The facts are that theradiolncent area is the anterior palatine foramen and theroot of the tooth is malformed and short, not absorbed. The radiograph is of the dry specimen shown in , in which the shadow of the anterior palatine foramenhas deliberately been cast at the apex of one of the centralincisors giving it (the foramen) the appearance of an ab-scess area. In order to cast the shadow of the foramen atthe apex of the central incisor tooth, the horizontal angleof the x-ray was somewhat as indicated in Fig. 87 by ar-row No 1. Fig. 89. Another radiograph of Fig. 87, which likeF
