. Electro-radiographic diagnosis; a book on the electric test for pulp vitality, giving the technic of its use in detail and submitting clinical evidence of its absolute necessity to dental diagnosis . over thefirst molar, the one on the readers left.

We have seen the necessity of checking upx-ray findings with the electric test. Now let me illus-trate the necessity of checking up pulp test findings withradiographs. The u|)per cuspid was quite definitely nega-tive to the strongest current. The radiograph shows thereason for it; the pulp has receded away above the gumline. The pulp is vital but the current could not pene-trate the secondary dentin to the pulp. Fig. 54. The lower cuspid responded positive but veryweak (+VA¥). The reason it responds so weakly to theelectric test is seen in the radiograph, , the large pulpstone. The first molar is abscessed. Considerable peri-dontoclasia about the cuspid.
