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...
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 ...
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 ...
Background and Aim: Since the external root resorption is not detectable clinically, therefore radiographic examination is very important for diagnose, Therefore, the purpose of this study is to compare the diagnostic efficiency of conventional, digital and CBCT radiography in detecting of external root resorption. Materials and Methods: In this descriptive-analytic study, after radiographic a...
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...
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...
Management of internal root resorption is a challenge to the endodontists. If it is left untreated, it may lead to the destruction of the surrounding dental hard tissues. Despite, routine obturation techniques are often employed without considering the best technique to solve this problem. This study presented a case of internal root resorption and apical periodontitis affecting tooth 12 (FDI) ...
external root resorption of permanent teeth is a multifactorial process. several etiologic and predisposing factors have been related to external root resorption. idiopathic external root resorption is defined as cases of external root resorption without a distinct etiologic factor. this article presents an extensive idiopathic external root resorption of maxillary first molar with irreversible...
Statement of Problem: One of the dental lesions which is mainly diagnosed by periapical radiography is apical root resorption Diagnosis of the presence and extension of this lesion can put some effects on its treatment plan and prognosis. Purpose: The aim of the present study was to evaluate the efficacy of periapical radiography on apical root resorption diagnosis. Materials and Methods: In th...
