OBJECTIVE To elucidate possible treatment-related etiological factors--such as, duration of treatment and apical displacement--for external root resorption. DESIGN Meta-analysis of the available English-language literature. INCLUSION & EXCLUSION CRITERIA Papers with a sample size > 10, fixed appliances, pre- and post-operative radiographs, and apical displacement recorded were included. His...

Background Patients who received orthodontic treatment are likely to have apical root shortening. It appears that external apical root resorption results from a combination of patient-related risk factors such as genetic influences, systemic factors, and orthodontic treatment-related factors. Regarding the fact that the anterior segmental osteotomy (ASO) has been known for its possibility of co...

Root resorption is loss of dental hard tissue as a result of clastic activities. The dental hard tissue of permanent teeth does not normally undergo resorption, except in cases of inflammation or trauma. However, there are rare cases of tooth resorption of an unknown cause, known as "idiopathic root resorption." This report would discuss a rare case of multiple idiopathic resorption in the perm...

this paper reports multidisciplinary treatment of a dental trauma case to achieve a favorable prognosis. a healthy 14-year-old girl reported avulsion of teeth 11 and 21 which had occurred three months earlier. the initial treatment consisting of replantation with a semi-rigid splint was performed in hospital. at presentation, the patient was still using the semi-rigid splint. the clinical exami...

BACKGROUND/AIM External replacement resorption (ankylosis-related) is a severe complication leading eventually to tooth loss. Little information exists regarding the influence of variables such as degree of intrusion or treatment method on the development of replacement resolution in intruded permanent incisors. The aim of this study was to report the most frequently involved age group, the pre...

Root resorption is a pathological process that causes a shortening of the dental root. Although this condition is generally asymptomatic and missed in diagnosis, it may result in tooth mobility and even tooth loss if not diagnosed and treated early (Ahangari et al., 2010). In orthodontics, induced inflammatory root resorption is a form of pathologic root resorption related to the removal of hya...

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 ...
