the present report reviews the diagnostic and treatment challenges of a mandibular molar with previous root canal treatment and signs of a procedural mishap, i.e. furcal radiolucency and localized swelling of the gingival margin in which a sinus tract was present. by tracing the sinus tract, it became evident that the lesion originated from the furcation area, not the root apices. this case was...

introduction: adequate seal of iatrogenically perforated area within the root canal system can improve the long term treatment prognosis. this in vitro study evaluated the sealing ability of mineral trioxide aggregate (mta), calcium-enriched mixture (cem) cement and biodentine in repair of furcation perforation in primary molars. methods and materials: a total of 61 freshly extracted primary ma...

objective: the purpose of this study was to investigate the histological response to delib-erate perforation repaired using amalgam or mta either immediately or with delay on cats’ molars. materials and methods: twenty-eight molar teeth from four cats were used in this ex-perimental randomized study. after preparing the access cavity, the floor of pulp cham-bers were deliberately perforated wit...

introduction: in ramadan, healthy adult muslims are obliged to fast. prolonged fasting increase gastric acid and pepsin levels, which promote the risk of duodenal ulcer perforation (dup). effects of ramadan fasting on dup have not been thoroughly studied yet, and the limited number of studies investigating the impact of ramadan fasting on dup yielded discrepant results. this study aimed to eval...

root perforations are an undesired complication of endodontic treatment which result in loss of integrity of the root, and adversely affect the prognosis of the treatment. recently, iranian mineral trioxide aggregate (root mta) has been introduced as an ideal material for perforation repair. in this article a successful repair of strip root perforation of mandibular molar using root mta is pres...

Mycotic aortic aneurysms account for 1–3% of all aortic aneurysms. The management of this disease is controversial. Since open surgical repair is associated with high morbidity and mortality rates, endovascular aneurysm repair is an alternative treatment method with promising early and midterm outcomes, although its long-term durability is unknown.Secondary aortoenteric fistulas may occur iatro...

Aortic valve regurgitation caused by a leaflet perforation occurs most often with infective endocarditis involving the aortic valve. Although rare, leaflet perforation can be caused by suture-related injury during cardiac operations, such as mitral valve replacement, ventricular septal defect (VSD) repair, and repair of an ostium primum atrial septal defect. Few reports have described this form...

Introduction: Although perforation of the esophagus, in the anterior cervical spine fixation, is well established, cases with delayed onset, especially cases that present pseudodiverticulum, are not common. In addition, management of the perforation in this situation is debated.  Case Report:   Delayed esophageal pseudodiverticulum was managed in two patients with a history of anterior spine fi...

A combined septal perforation repair and rhinoplasty was performed in 80 patients presenting with septal perforations (size 1 to 5 cm) and external nasal deformities. The external rhinoplasty approach was used for all cases and the perforation was repaired using bilateral intranasal mucosal advancement flaps with a connective tissue interposition graft in between. Complete closure of the perfor...
