Statement of Problem: The goal of a successful endodontic surgery is to establish an adequate seal in apical region. Therefore during surgery, root-end resection is essential for an appropriate situation and proper access.Purpose: The aim of this study was to determine the most appropriate root-end resection angle to establish adequate apical seal in periapical surgeryMaterials and Methods: For...
congenital left ventricular diverticulum is a rare cardiac malformation. two categories of congenital ventricular diverticulum have been identified with regard to their localization: apical and non-apical. apical diverticula are always associated with midline thoraco-abdominal defects and other heart malformations. non-apical diverticula are always isolated defects. diagnosis is established by ...
the importance of the role played by bacteria in the pathogenesis of pulpal and apical disease has been established. one of the characteristics of apical periodontitis is apical bone resorption, which is due to apical immune response to bacterial infection. recently, novel bacterial complex lipid called phosphorylated dihydroceramides has been discovered to be of inflammatory activators. the ba...
introduction: preserving the apical root structure during cleaning and shaping of the canal has always been a challenge in endodontics particularly when the root canals are curved. the purpose of this in vitro study was to compare the apical transportation induced by the reciproc and biorace rotary systems in preparing the mesiobuccal root canal of the human maxillary molars. materials and meth...
a 20-year-old man presented with the history of pain and swelling in the anterior maxillary segment. the periapical radiography was indicative of a dental anomaly in right maxillary lateral incisor. due to the insufficient information from conventional radiography, cone-beam computed tomography (cbct) was ordered. cbct showed apical root resorption, large apical lucency and two separate canals ...
Background and Aim: Achieving appropriate seal in canal obturation is the main goal of endodontic therapy. However, in some cases, it can not be obtained by non-surgical procedures alone. Retrograde surgery is one of the most common procedures in endodontics. Apical seal improvement can be obtained by root end filling and decreasing the root end resection angle (bevel angle). The aim of this st...
