The purpose of this study was to identify risk factors for apical root resorption in adult orthodontic patients. Standardized periapical radiographs of maxillary anterior teeth and cephalograms made before and after treatment and treatment charts of 343 adults, representing groups of consecutively treated patients from four orthodontic practices, were examined. Apical root resorption was calcul...

The periapical area in teeth with chronic lesions is characterized by changes in the adjacent bone structure and periodontal ligaments, as well as in the cement and dentine. In a large percentage of cases, the apical physiological constriction is ether absent or expanded. The absence of a constriction makes it a challenge to achieve satisfactory treatment results.The present case report describ...

The purpose of this study was to compare the severity of apical root resorption occurring in patients treated with a standard edgewise and a straight-wire edgewise technique, and to assess the influence of known risk factors on root resorption incident to orthodontic treatment. The sample consisted of 80 patients with Angle Class II division 1 malocclusions, treated with extraction of at least ...

Inflammatory external root resorption (IERR) is a pathological phenomenon of microbial origin. This study 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 in the uppe...

Endodontic treatment of teeth with perforating internal root resorption represents a clinical challenge. In most cases, extraction of the tooth and subsequent replacement with an osseointegrated implant is indicated. Presented herein is a case report of a maxillary lateral incisor with advanced perforating internal root resorption in the middle third of the root and the presence of a sinus trac...

Management of a case of internal root resorption is a challenge to the endodontists.Internal resorption of teeth is an insidious process and is generally found in teeth with previous history of trauma.It may occur in cases with chronic pulpal inflammation, following caries or due to trauma in the form of an accidental blow. Internal resorption is very often noticed in anterior teeth, due to the...

Platelet-rich fibrin matrix (PRFM) is an autologous biologic material created by centrifugation of blood. This study quantified ridge changes associated with the healing of 21 extraction sites using PRFM alone as a graft. Standardized measurements of ridge width and height were recorded at extraction, after graft placement, and after 4 months of healing. Mean width resorption 3 and 5 mm apical ...
