OBJECTIVES To assess the accuracy of coronal and sagittal CT sections to detect cavities simulating root resorption. MATERIAL AND METHODS 60 mandibular incisors were embedded in plaster bases, and cavities with 0.6, 1.2 or 1.8 mm in diameter and 0.3, 0.6 or 0.9 mm in depth (small, medium and large cavities) were drilled on the buccal surfaces with high-speed round burs with diameters of 0.6, ...

OBJECTIVE To assess the prevalence of severe external root resorption and its potential risk factors resulting from orthodontic treatment. METHODS A randomly selected sample was used. It comprised conventional periapical radiographs taken in the same radiology center for maxillary and mandibular incisors before and after active orthodontic treatment of 129 patients, males and females, treated...

INTRODUCTION The purpose of this study was to compare, in a split mouth design, the external apical root resorption (EARR) associated with orthodontic treatment in root-filled maxillary incisors and their contralateral teeth with vital pulps. METHODOLOGY The study sample consisted of 38 patients (14 males and 24 females), who had one root-filled incisor before completion of multiband/bracket ...

INTRODUCTION Guided tissue regeneration (GTR) is a successful treatment procedure of periodontal reconstructive surgery. Adverse effects can be observed after GTR procedure, but external root resorption is rarely reported at clinical studies. Invasive cervical resorption is a clinical term used to describe a relatively uncommon, insidious, and often aggressive form of external root resorption. ...

Cervical external root resorption can be present in natural teeth, involving one or more teeth in the same patient. The incidence of these lesions appears random and the etiology remains unclear. Cervical external root resorption has been considered a difficult clinical situation, and its diagnosis and treatment of the defect challenging. The present report describes a case of multiple external...

This study investigated the association of appliance type and tooth extraction with the incidence of external apical root resorption (EARR) of posterior teeth following orthodontic treatment. Pre- and posttreatment orthopantomograms were compared for 97 patients and a 4-grade ordinal scale used to measure EARR. The incidence of EARR was positively associated with tooth position (P < .001), appl...

INTRODUCTION Tooth avulsion is a real dental emergency. If immediate replantation is not performed, the avulsed tooth may be lost due to inflammatory or replacement resorption. This animal study aimed to evaluate the bone response to the titanium coating of the root surface as an artificial barrier, and prevention of resorption of avulsed teeth. METHODS AND MATERIALS This experimental study w...

objective: : root resorption is a complication of orthodontic treatment and till date, there is a dearth of information regarding this subject. the aim of this study was to determine the relationship between orthodontic force and genetic expression of tgf-β(as an inflammatory cytokine) using the rt-pcr technique in rats. moreover, realization of the level of gene expression may help in the diff...

UNLABELLED THE MAIN OBJECTIVE of the study was to determine the extent of external apical root resorption at the end of orthodontic treatment and to identify the possible pre-treatment and treatment factors that would allow to predict the possible incidence of root resorption before the start of treatment. PATIENTS AND METHODS Panoramic radiographs of 75 patients that had been treated with fu...
