This study evaluated the technical quality of root canal treatment (RCT) and detected iatrogenic errors in an undergraduate dental clinic at the College of Dentistry, Taibah University, Saudi Arabia. Dental records of 280 patients who received RCT between 2013 and 2016 undertaken by dental students were investigated by retrospective chart review. Root canal obturation was evaluated on the basis...

abstract introduction: in root canal therapy some accidents may happen that affects the prognosis of the tooth. for example, when preparing access cavity, perforation of furca is a possibility that leads to tooth loss. important factors in prognosis of furcation perforation include: the kind of materials used, area that perforation has happened in, time in which perforation is sealed and skill ...

PURPOSE The aim of this in vitro study was to determine the sensitivity and specificity of cone-beam computed tomography (CBCT) and digital periapical radiography in the detection of mesial root perforations of mandibular molars. MATERIALS AND METHODS In this in vitro study, 48 mandibular molars were divided into 4 groups. First, the mesial canals of all the 48 teeth were endodontically prepa...

Internal inflammatory root resorption is a relatively rare resorption that begins in the root canal and destroys surrounding dental hard tissues. Odontoclastic multinuclear cells are responsible for the resorption, which can grow to perforate the root if untreated. The initiating factor in internal root resorption is thought to be trauma or chronic pulpal inflammation, but other etiological fac...

AIM To highlight one of the possible complications associated with the inter-radicular placement of orthodontic miniscrews. SUMMARY This case report describes the endodontic treatment and surgical repair of an iatrogenic root perforation involving a maxillary first molar tooth following the placement of an orthodontic miniscrew placed for anchorage purposes in the treatment of an adult patien...

Abstract There are very few case reports of percutaneous device closure anterior mitral leaflet perforation. We describe here a simultaneous aortic root perforation and These cases challenging as they presently done in high-risk patients with no guidelines described to date.

objective: furcal perforation is an undesirable complication that may occur during root canal therapy and seriously compromises the prognosis of endodontic treatment. the prognosis of furcal perforation repair depends on the prevention of bacterial infection of the perforation site. thus, use of a biocompatible material for complete sealing of the perforation site is critically important. this ...

STATEMENT OF PROBLEM One of the most challenging procedural accidents during pulpotomy of primary molars is furcal perforation. To prevent bacterial invasion, the perforation site should be sealed as soon as possible. PURPOSE The aim of the current study is to investigate the ability of the pro-root MTA and new endodontic cement (NEC) in repairing the furcation perforations of primary molar t...
