The next picture shows the same toothafter the root amputation. In the next picture we see how beauti-fully the bone has adhered around the stub of one of these ampu-tated roots. This amputation was made in January, 1896. Thepatient claims it to be the strongest, solidest tooth she ever had. Inthe next we see a broken broach protruding through the apex farinto the tissue. In this picture (Fig. 21) we see much of interest. The radio-graph was taken to locate a piece of a cambric needle which thepatient had broken in the root while trying to relieve an was thought to have been forced through into the tissue as theapex was found open. It is easily seen lodged in the root, which wasevidently bifurcated. This picture also shows beautifully the rela-tion in this case of the teeth to the antrum. You will observe thatthe roots of the second molar penetrate nearly half way up througlithat cavity. The value of X-rays in Orthodontia ^s almost heyond.
