It is thought that the stress concentration at the root apex caused by orthodontic force induces root resorption. The purpose of this study was to investigate stress distribution at the root in cases of deviated root shapes using finite element models (FEMs). To clarify this, five three-dimensional FEMs divided by deviated root shape (normal, short, blunt, bent root apex, pipette shape) were co...

One primary objective of endodontic therapy is to establish an adequate seal with the root canal filling material. The placement of an immediate amalgam buildup at obturation, in conjunction with rubber dam isolation, allows an endodontic seal to be extended from the foramen to the cavosurface margin. As a result of this immediate buildup, the length of the seal and the longevity of the endodon...

INTRODUCTION Intra-radicular disc herniations are rare disorders with only few cases reported in literature. In most of these cases there is evidence of some part of the disc in adjacent area. We present a case of completely intra-radicular disc which was misdiagnosed as nerve root tumor as there was no evidence of disc prolapse at the time of diagnosis. CASE PRESENTATION 51 year old male pre...
