. Orale Roentgoenologie : Eine Roentgen-Studie über die Anatomie und Pathologie der Mundhöhle. Lm ist der zu verwendende Stein und sollte zwischen den Zähnen so weit wie möglich nach hinten platziert werden.der Kopf des Patienten sollte in einem extremen Winkel nach hinten gebogen werden, damit der Strahl von der Unterkieferhöhle aus gerichtet werden kann Region auf dem Film. Wenn sich die Kalkül in der Unterkieferdrüse selbst oder in der Ohrspeicheldrüse befindet, liefert eine extraorale Platte die genauesten Informationen.

. Oral Roentgenology : a Roentgen study of the anatomy and pathology of the oral cavity . lm is the bestone to use and should be placed between the teeth as far back as possible.The patients head should be bent at an extreme backward angle so thatthe ray can be directed from the submandibular region on the film. Ifthe calculus is in the submaxillary gland itself or in the parotid gland, an extraoral plate will give the most accurate information. Roentgenology of Salivary Calculi Figure 211. Patient: Mrs. C. A. P. History: Patient complained of swelling under the tongue which varied in sizeand was usually largest before meal times. Roentgen Examination: Shows a radiopaque object on the right side of the floorof the mouth opposite the first molar. Operative Findings: An incision was made in the mucous membrane of the floorof the mouth to expose the submaxillary duct and sublingual gland. The duct did notcontain any foreign material, but the sublingual gland contained a salivary calculussurrounded by a small amount of pus. ROENTGEXOGILiPHIC STUDY OF PATHOLOGICAL COXDITIOXS 155.

History: Patient had tumor-like swelling on cheek and felt a hardsubstance under the skin, but no pain. Roentgen Examination: Plates by courtesy of Dr. A. W. George.Two plates had to be taken to ascertain the location of the foreign bodies.From the lateral view, shown in Figure 212, one might think the radio-paque foreign bodies were located in the maxillary sinus, but the secondplate shows that they are outside of the maxillary bone and from thelocation in both plates, we may conclude that they are in the parotidgland. Operative Findings: The foreign bodies, after being removed, werefound to be small lumps and felt like cartilage. Pathological examinationshowed them to be organized thrombi, which had become calcified. Thesephleboliths showed concentri
