Background and Aims: Apical root resorption is an adverse side effect of fixed orthodontic treatment which cannot be repaired. The aim of this study was to use panoramic radiographs to compare the root resorption before and after the orthodontic treatment with standard edgewise .018 appliance. Materials and Methods: The before and after treatment panoramic views of sixty-three patients needed ...
Introduction: Presence of external root resorption in second molars associated with impacted mandibular third molars was not rare. The neglect of this issue may leads to penetration of the pulp and loss of the second molars. The aim of this study was to investigate the incidence and risk factors affecting the external root resorption in second molars associated with mandibular impacted third mo...
internal inflammatory root resorption (iirr) is a rare condition of the root canal and if it is left untreated it may lead to destruction of the surrounding dental hard tissues. odontoclasts are responsible for this situation which can potentially perforate the root. many initiating factors have been mentioned for iirr, almost all causing chronic inflammation in the vital pulp. iirr is usually ...
invasive cervical resorption is a condition that affects the root surface area below the epithelial attachment. multiple treatment modalities are advocated, involving exposure of the invasive defect, removal of the granulation tissue and sealing with various restorative materials. this report demonstrates conservative treatment of a patient presenting with peri-apical periodontitis in upper rig...
Background and purpose: Internal inflammatory root resorption (IIRR) is an uncommon lesion in permanent tooth that could lead to destruction of root and the surrounding dental hard tissues if it is left untreated. This article describes treatment of an extensive perforating internal root resorption in a maxillary second premolar using mineral trioxide aggregate (MTA). Case report: After chem...
Tooth avulsion is one of the most complicated dental traumatic injuries. Pulp necrosis and root resorption are the most common complications resulting from avulsion. External root resorption following tooth replantation can be inflammatory or replacement resorption (ankylosis). This report presents the treatment of progressive external root resorption on a permanent maxillary left central incis...
introduction: external root resorption (err) is associated with physiological and pathological dissolution of mineralized tissues by clastic cells and radiography is one of the most important methods in its diagnosis. the aim of this experimental study was to evaluate the accuracy of conventional intraoral radiography (cr) in comparison with digital radiographic techniques, i.e. charge-coupled ...
inflammatory external root resorption (ierr) after orthodontic treatments is an unusual complication. this case report describes a non-vital maxillary premolar with symptomatic extensive ierr (with a crown/root ratio of 1:1) after receiving orthodontic treatment. the first appointment included drainage, chemo-mechanical preparation of the canal and intra-canal medication with calcium hydroxide ...
abstract : inflammatory external root resorption (ierr) is a pathological phenomenon of microbial origin. this stu dy reports a case of external apical inflammatory root resorption of maxillary incisors associated with periradicular lesions in a 22 year old female, which was successfully treated by one-visit root canal therapy (rct). radiographic investigation revealed periapical radiolucencies...
external root resorption may be an uncontrolled phenomenon, and the most known interventions have no effect. even progressive external root resorption may not be controlled by long term ca(oh)2 therapy. currently, there are no treatment options for vital tooth that suffer from root resorption. this invasive resorption can lead to extraction of the tooth. the use of new technologies such as low ...
