introduction: the aim of this study was to compare the diagnostic value of cone-beam computed tomography (cbct) and periapical (pa) radiography in detecting internal root resorption. methods and materials: eighty single rooted human teeth with visible pulps in pa radiography were split mesiodistally along the coronal plane. internal resorption like lesions were created in three areas (cervical,...

for management of a symptomatic maxillary lateral incisor with dull pain on chewing, suppurative sinus tract, defective metal-ceramic crown and iatrogenic internal root resorption, an interdisciplinary approach was taken. two-visit nonsurgical treatment with calcium-enriched mixture (cem) cement, replacement of metal-ceramic crown with all-ceramic crown and corrective periodontal plastic surger...

introduction: conventional methods for diagnosis of external root resorption (err) are based on clinical findings and x-ray observations which are not appropriate for early diagnosis. the present study assessed the effect of different sizes and field of views (fovs) in the diagnosis of simulated external root resorption by cone-beam computed tomography (cbct). methods and materials: in this dia...

external inflammatory root resorption (eir) represents a challenge in endodontic practice. eir commonly occurs after dental trauma that results in periodontal ligament injury, pulp necrosis and subsequent infection.  treatment of eir is based on disinfecting the root canal system through chemomechanical procedures and then filling it with calcium hydroxide or triple antibiotic paste. dental tra...

This study evaluated the use of zoledronic acid, a resorption inhibitor, as a medication for root resorption treatment of late replanted teeth. Twenty-four maxillary right central incisors of rats were avulsed and kept dry for 30 min. Then, the teeth were divided into 2 groups. In group I, root surface was treated with 2% sodium fluoride for 20 min; in group II, 10-6M zoledronic acid solution w...

Root resorption is a pathological process involving loss of hard dental tissues. It may occur as a consequence of dental trauma, orthodontic treatment, and bleaching, and occasionally it accompanies periodontal disease. Although the mechanism of resorption process is examined in detail, its etiology is not fully understood. Wide open apical foramen is more difficult to manage and the root canal...

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...

Occasionally, general dentists are challenged with providing restorative treatment for a postorthodontic patient who has had moderate to severe root resorption. When this happens, a number of questions about the cause of such resorption and the appropriate treatment arise in the dentist's mind. This article will describe the orthodontic and restorative management of three patients with severe m...
