This study was an attempt to investigate electron microscopical difference between enamel and enamel droplet, and cementum and cementicle in periodontal disease. A total of 41 molar teeth with furcation involvement and impossible of preservative treatment were used in this investigation. Those teeth were fixed in 10% neutral formalin, the moment they were extracted. Soft tissues from most of the samples were removed with ethylendiamin. Enamel droplet and cementicle in surface of root furcation were observed under the SEM and TEM. The ground section were also prepared and observed by polarized light microscopy and microradiography. It was observed in the root furcation that such an aberration was a strong predisporing factor in the initial break down where enamel projection was present. SEM and TEM finding revealed that surface of the enemel droplet and cementicle in the furcation were different from normal enamel and cementum.
