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 . lication of the electric test. Fig. 62. Another view of the parts in which the angleat which exposure was made was correct. No distortionof the image and the abscess shows. Figs. 63 and 64. When Ave have reason to believe atooth is pulpless, or we know it as we do in the caseof the shell crowned upper molar because we can see somecanal filling, then we are fully aware of the necessity ofgetting a good radiographic view of the tooth. But if wehave no idea whether the pulp is vital or not then we donot know exactly how thorough our radiographic exam-ination should be. Fig. 63 fails to show the abscessof the upper molar, while Fig. 64, the last one made,shows it, or, to be meticulous, it shows a radiolucent areawhich I take to be an abscess cavity. It is not infre-quently necessary to deliberately distort upper molars inorder to cast the shadow of the mesiobuccal or disto-buccal roots far enough mesially or distally to observethe tissues at their apices.
