the aim of this case report was to describe the clinical management of an unusual dens invaginatus type 3. a case of dens invaginatus in a maxillary lateral incisor with a periapical lesion is reported. the patient presented with pain and localized swelling. despite the complex anatomy and diagnosis of dens invaginatus, non-surgical root canal treatment was performed successfully. key learning ...

INTRODUCTION The aim of this study was to evaluate the accuracy of two electronic apex locators (Smarpex and NovApex) in detecting apical perforation. MATERIALS AND METHODS After access cavity preparations, the working length was determined by the first examiner before and after perforation with a stereomicroscope by introducing a K-file size 10 into the canal and size 25 K-file up to the per...

Root perforation connect root canal spaces with periodontal tissues. The connection may occur as result of iatrogenic causes during root canal treatment (at the level of floor of the coronal cavity or at different levels of the root) or during prosthetic treatment of post canal trioxide aggregate(MTA), composite resin, glass ionomer cement and calcium hydroxide, most of these penetration. (1) A...

BACKGROUND AND PURPOSE There are no reports in the literature on the influence of learning on the pedicle screw insertion. We studied the effect of learning on the rate of screw misplacement in patients with adolescent idiopathic scoliosis treated with segmental pedicle screw fixation. METHOD We retrospectively evaluated low-dose spine computed tomography of 116 consecutive patients (aged 16 ...

UNLABELLED Root perforation is an unwanted incident which may occur at any stage of endodontic treatment and can adversely affect tooth prognosis. AIM To compare the recovery rate after treatment of root perforations in the interradicular area of the molars, using two different materials: MTA and ceramic nanoparticles mineral cement DiaRoot BioAggregate, by a clinical-radiological and statist...

Iatrogenic duodenal perforation associated with endoscopic retrograde cholangiopancreatography (ERCP) is a very uncommon complication that is often lethal. Perforations during ERCP are caused by endoscopic sphincterotomy, placement of biliary or duodenal stents, guidewire-related causes, and endoscopy itself. In particular, perforation of the medial or lateral duodenal wall usually requires pro...

Aim To report the treatment and follow-up of a maxillary central incisor with internal resorption managed by root canal treatment, white mineral trioxide aggregate (MTA) repair and a fibre-glass post for reinforcement....

Perforation of the proximal descending aorta occurred in a patient on intra-aortic balloon pump (IABP) support after emergency coronary intervention for acute myocardial infarction. The IABP catheter was inserted under fluoroscopic guidance into the right femoral artery without difficulty, but after 8 h on IABP support the patient went into shock with a left hemothorax. Emergency surgery was pe...
