Oral Roentgenology : a Roentgen study of the anatomy and pathology of the oral cavity
A 1917 dental radiography manual by Kurt H. Thoma, published in Boston by Ritter & Company for dentists and dental students learning to read X-ray plates of the mouth. Its plates are small halftone reproductions of dental radiographs with rounded corners, showing roots, jawbone and bright white metal fillings and crowns against smoky grey and black grounds; useful for high-contrast skeletal forms, grainy photographic texture and rounded-rectangle framing.
