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...

Introduction:Orthodontic treatment is associted with a risk of root resorption.The aim of this study was to determine the risk of moderate and sever root resorption in orthodontic patients treated with fixed orthodontic appliance.   Method:A case-control study was performed on 70 orthodontic treated patients with moderate and sever root resorption and 70 controls matched for age,sex,duration ...

abstract : dens invagination (di) is a developmental abnormality of teeth which frequently results in a complex internal anatomy of the root canal system. di type 3 is an anomaly characterized by infolding of enamel and dentin extending into the root apex. this may present difficulties when forming a diagnosis and treatment plan. many treatment modalities have been presented in case reports for...

resorption of tooth structures can occur as a result of physiological, pathological, and idiopathic factors. early diagnosis and appropriate treatment can prevent its serious complications. this case report presents surgical endodontic management of a trauma-induced perforating external root resorption, which was diagnosed with the help of cone beam computed tomography. following root canal tre...

INTRODUCTION The choice of single- versus multiple-visit root canal treatment for infected teeth is in dispute. The purpose of this systematic review was to compare the healing rate and post-obturation pain of single- versus multiple-visit root canal treatment for teeth with infected root canals. METHODS An exhaustive literature search combined with specified inclusion criteria was performed ...

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...
