Multiple idiopathic external root resorption is a rare pathological condition usually detected as an incidental radiographic finding. External root resorption of permanent teeth is a multifactorial process related to several local and systemic factors. If an etiological factor cannot be identified for root resorption, the term "idiopathic" is applied. This report presents a case of multiple idi...

OBJECTIVES To investigate root resorption after 6 months of active orthodontic treatment and its relation to possible risk factors. MATERIALS AND METHODS Ninety-seven patients (10-18 years) with a Class I malocclusion and crowding treated with fixed appliance and premolar extractions were examined with cone beam computed tomography before and after 6 months of active treatment. The exposure c...

OBJECTIVE The aim of this study was to evaluate predisposing factors among patients who developed moderate or severe external root resorption (Malmgren's grades 3 and 4), on the maxillary incisors, during fixed orthodontic treatment in the permanent dentition. METHODS Ninety-nine patients who underwent orthodontic treatment with fixed edgewise appliances were selected. Patients were divided i...

The purpose of the present study was to clarify the prevalence and degree of root resorption induced by orthodontic treatment in patients with and without open bite. One hundred and eleven patients treated with multibracket appliances were retrospectively selected from the patients and divided into non-open bite (NOB) and open bite (OB) groups. The severity of root resorption and the root shape...

PURPOSE This study was performed to evaluate the incidence and degree of external apical root resorption of maxillary incisors after orthodontic treatment and to evaluate particular associated factors related to external apical root resorption. MATERIALS AND METHODS The records and maxillary incisor periapical radiographs of 181 patients were investigated. Crown and root lengths were measured...

Common complications of dento-alveolar trauma are pulp necrosis, pulp canal obliteration, periapical pathosis and root resorption. Different types of root resorption have been identified with traumatic injuries. Repair-related (surface), infection-related (inflammatory), ankylosis-related (osseous replacement) or extraradicular invasive cervical resorption are among the most common. Recent deve...

This case report describes an external apical root resorption resulted from the unusual root morphology of the neighbouring tooth. A 28-year-old female was referred to the department of endodontics with a complaint of intense pain in her maxillary second premolar tooth. The clinical and radiographical evaluation revealed an external apical resorption in the mesial root of the maxillary first mo...

External root resorption in posttreatment orthodontic patients, if severe, may jeopardize the retention of the tooth or teeth involved. Numerous studies (1-5) have been undertaken to determine the relationship between the frequency and severity of external root resorption and orthodontic movement. Some investigators found the incidence of root resorption to be low (6-9), while others found it t...
