(See Fig. 80.) Some operators preferto use the intra-oral method entirely, in making a generalexamination, but this, in the authors opinion, is a mis-take, for the reason that all areas of pathologic impor-tance are not accessible to these small Fig. 79.—Extra-oral radiogram of the right side made for purposes of general ex-amination. Suspicious areas are to be seen above the uoner first bicuspid and aboutroots of the lower second molar. An unerupted upper third molar is also visible. To Determine the Seat of Pericemental Infections Not infrequently it is a difficult matter to determinethe tooth responsible for a pericemental infection or analveolar abscess, as the inflammatory process may be inprogress in the region of several teeth, each of whichmay be under suspicion, or the infected area may be ata point remote from the suspected tooth. A radio-graphic examination will quickly settle all doubts, for theradiogram will reveal the source and determine whether i:;s DKNTAI; AND ORAL RADIOGRAPH! or not one or more teeth are involved.
