Root shortening as a result of apical root resorption is an undesirable consequence of orthodontic treatment. The objective was to determine the prevalence of external apical root resorption in a sample of Sudanese orthodontic patients treated with fixed appliances and to evaluate the association of treatment duration, age, gender and the type of malocclusion on the degree of external apical ro...

The aim of this case report was to present management of a case of multiple apical root resorptions due to orthodontic treatment in a 27-year-old adult female using implant supported crowns. External root resorption of the permanent teeth is a multi-factorial process. Well recognized causes of apical root resorption in permanent teeth include orthodontic therapy, trauma, periapical or periodont...

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 apical root resorption is a common phenomenon associated with orthodontic treatment. The factors relevant to root resorption can be divided into biological and mechanical factors. Some mechanical and biological factors might be associated with an increased or decreased risk of root resorption during orthodontic treatment. For mechanical factors, the extensive tooth movement, root torqu...

Introduction: Root resorption, generally expressed in a round apical shape, is one of the most common findings in the orthodontic clinic. Objective: To radiographically evaluate whether vital and endodontically treated teeth present similar severity of apical root resorption in response to orthodontic treatment. Methods: This study was conducted with twenty-eight patients who had one upper cent...
