Evaluation of periapical radiolucencies found in cadavers

摘要: There has been a recent resurgence of interest in investigative roentgenography. Bender and Seltzer1 showed that intrabony lesions often may not be detected roentgenographically unless there is per­ foration or considerable resorption the overlying cortical bone. They also pointed out extensive bone dis­ ease without roentgenographic evidence. The findings Shackman Harrison2 confirm this, as they were able to demon­ strate microscopically visible but roent­ genographically invisible metastases vertebrae long bones. Goldman, Millsap, Brenman,3 1957, removed entire buccal lingual plates jaw bones concluded “ . only density radiograph was affected when removed.” Limited observations peri­ apical pathoses studied roentgenographi­ cally made by Kronfeld.4 Perhaps most complete account oral pathosis found cadavers recorded Thoma 1918.5 He pre­ sented photographs several cadaver specimens with resulting from chronic periapical periodontal infection. Unfortunately, this work accompanied roentgenograms.
