This study identifies the most common microorganisms present in type III gold cast posts related to pulpal disease and evaluates the sterilization/disinfection method before cementation in the root canal. Forty-five type III gold cast posts were aseptically collected in sterile sealed plastic bags and taken to the microbiology laboratory to carry out the study: fifteen cast posts had no treatme...

statement of problem: endodontically treated teeth are more prone to fracture. the post and core are often used to provide the necessary retention for prosthetic rehabilitation. objectives: the purpose of this study was to: 1) compare the fracture strength of endodontically treated teeth restored either with nickel-chromium (ni- cr) post or non- precious gold-color alloy (npg) post compared to ...

The aim of this study was to evaluate if clinical experience, whether in relation to length of practice time and/or level of specialization influences the dentist's preference for using posts to restore endodontically treated teeth. A cross sectional study was carried out using a questionnaire with dentists (n = 276) in Pelotas, southern Brazil. Data were collected regarding clinical experience...

A buckle fracture is a stable fracture where there is a dorsal cortex compression of the distal radius. A total of 117 children with buckle fracture treated at our institution were randomised prospectively into two treatment groups: soft cast or rigid cast. The rigid cast group attended clinic after three weeks for removal of the cast. In the soft cast group, the cast was removed by parents at ...

CONTEXT Biliary cast syndrome is an unusual complication of orthotopic liver transplantation with serious clinical implications. Surgical management has been the mainstay of treatment.
