The histologic response to intentional perforation in the furcations of 28 mandibular premolars in seven dogs was investigated. In half the teeth, the perforations were repaired immediately with either amalgam or mineral trioxide aggregate; in the rest the perforations were left open to salivary contamination before repair. All repaired perforations were left for 4 months before histologic exam...

OBJECTIVE The objective of this study was to evaluate the cytotoxicity of furcal perforation repair materials, GI and MTA, using cell culture technique. STUDY DESIGN The extract of ProRoot MTA and Ketac Molar were treated on PDL cells in a 96-well tissue-culture plate. Cell proliferation after an incubation period of 3 days was determined by using MTT assay. RESULTS The growth of cultured h...

Background: Nasal septal perforations (NSPs) are nasal septum defects as a result of necrosis to the cartilage or bony tissues in addition their mucous membrane on both surfaces. current work aimed estimate endoscopically assisted repair medium-sized perforation using inferiorly based rotational flap together with Platelet rich plasma (PRP).
 Methods: It was randomized controlled double-bl...

BACKGROUND Connective tissue autografts are commonly used as interpositional grafts between septal flaps in the repair of septal perforations. The most common graft materials used include temporalis fascia and pericranium, both of which are accompanied by donor site morbidity, do not provide septal bulk, and are exceedingly thin and difficult to manage. OBJECTIVE To study the use of an acellu...

Objectives: To study the result of primary repair with ileostomy in cases typhoid ileal perforation.
 Study Design: Quasi-experimental study.
 Place and Duration Study: Department Surgery, Jinnah Postgraduate Medical Center, Karachi Pakistan, from May 2019 to Jun 2020
 Methodology: Participants who were operated on for perforation included, while patients presented a hollow viscu...

Early diagnosis followed by primary repair is the best treatment for spontaneous esophageal perforation. However, the appropriate management of esophageal leakage after surgical repair is still controversial. Recently, the successful adaptation of vacuum-assisted closure therapy, which is well established for the treatment of chronic surface wounds, has been demonstrated for esophageal perforat...

BACKGROUND Perforation of the thoracic esophagus is a formidable challenge. Treatment and outcome are largely determined by the time to presentation. We reviewed our experience with esophageal perforations to determine the overall mortality and whether the time to presentation should influence management strategy. METHODS A retrospective chart review was performed on all patients treated for ...

OBJECTIVE • To examine the clinical characteristics and long-term outcomes of patients with bladder perforation requiring open surgical repair as a complication of transurethral resection of bladder tumour (TURBT). PATIENT AND METHODS • A search of our institutional database yielded 4144 patients who underwent TURBT from 1996 to 2008, of whom 15 (0.36%) required open surgical intervention to ...

The purpose of treating furcal perforation is to seal the artificial communication between canal space and periradicular tissue prevent periodontal breakdown. duration, size location were identified as primary prognostic factors for determining successful treatment. Mineral trioxide aggregate (MTA) has been regarded an ideal material repair owing its excellent sealability biocompatibility. pres...

OBJECTIVES/HYPOTHESIS To report a technique for septal perforation repair that does not rely on intraoperative mucosal closure of the perforation defect. STUDY DESIGN Case series with prospective and retrospective data collection. METHODS Nine patients received multilayer interposition grafts and no attempt at intraoperative mucosal closure for repair of septal perforations. Eight patients ...
