 AB : The author has studied roentgenographic images of temporomandibular articulation using various conventional roentg enographies.
 The roentgenographic images have been obtained by application of the contrast media on the glenoid fossa and condylar head in human dry skull. Comparing the various roentgenograms by Modified Transcranial projection, A-P T.M. articulation projection, Reverse Town projection, Mayer projection, and Bregma-Menton projection;
 The author has drawn following results.
 1. The sharp radiographic details were obtained by all technics used except the Bregma-Menton projection which seemed t o be impractical to the study of T.M.J. because of the shortened image of condylar head.
 2. The best image of the condyle-fossa relationship was appeared by Modified Transcranial projection and better image w as acquired by Orbito-Ramus projection, but there were all inferior in Reverse Towne projection, Mayer projection, and B regma-Menton projection.
 3. In all of the above techniques, the radiograhpic images of condylar head were clear and appeared to be the convex ty pe in Modified Transcranial projection, the angled type in Orbito-Ramus and Reverse Towne projection, the flat type in M ayer projection, and the distorted angled type in Bregma-Menton projection.
 4. The radiographic image of condylar head was shortened in Bregma-Menton projection only and was magnified somewhat in other projections.
