THE USES OF THE RADIOGRAPH IN DENTISTRY 253 Immediately after the filling of the canals of a lower second molar apatient suffered most severe pain in the region of the filled tooth. Aradiograph was made and showed the canal filling penetrating the apicalforamen of the distal root, projecting into the inferior dental canal, and. Fig. 292. The arrow points to an impacted upper, third molar, the cause of idiopathic neu-ralgia, from which the patient had suffered recurrently for from between twenty-five to thirtyyears. (Radiograph by A. M. Cole, of Indianapolis.) doubtless pressing the inferior dental nerve. An effort to remove thecanal filling met with failure, and the tooth was extracted to relieve thepatient of the intense pain. Again I do not print radiographs of the casebecause the prints are not sufficiently clear to permit of good half-tonereproductions. 56.
