External fixation of the cervical spine is usually obtained by means of a “ Minerva” plaster-of-Paris jacket, a device by no means always satisfactory. The patient usually finds it heavy, and frequently hot and uncomfortable. Even the best fitting “ Minerva “ plaster allows more cervical movement than the surgeon may desire, and though immobilisation may be improved by the incorporation of a sk...

INTRODUCTION The objective of this validation study was to compare standard plaster models (the current gold standard for cast measurements) with their digital counterparts made with emodel software (version 6.0, GeoDigm, Chanhassen, Minn) for the analysis of tooth sizes and occlusal relationships--specifically the Bolton analysis and the peer assessment rating (PAR) index and their components....

Barite plaster has been largely used as shielding material in installations housing gamma radiation sources as well as x-ray generating equipment, in order to minimize exposure to individuals. However, some physical characteristics, such as density, plasticity, resistance to compression and radiation attenuation for the different types of barite plaster commercially available in Brazil are not ...

A numerical finite difference study has been earned out for two dimensional radiation-natural convection interaction phenomena in a vertical circular pin located at a non-participating (i.e. transparent) fluid. The coupled conservation equations in boundary layer (continuity, momentum, and energy equations) and pin energy equation are solved simultaneously using modified box method and fully im...

PURPOSE To compare two different impression techniques for implants in totally edentulous patients. MATERIALS AND METHODS A total of 38 patients had impressions taken both using plaster and splinted vinyl polysiloxane (splinted-VPS). Two casts per patient were generated and allocated as test (plaster) and control (splinted-VPS) cast groups according to a randomised cross-over design. One of t...

Postherpetic neuralgia (PHN) is a common, very painful, and often long-lasting complication of herpes zoster which is frequently underdiagnosed and undertreated. It mainly affects the elderly, many of whom are already treated for comorbidities with a variety of systemic medications and are thus at high risk of drug-drug interactions. An efficacious and safe treatment with a low interaction pote...

The fundamental factors in the diagnosis in the orthodontic treatment are the spacing condition, tooth size, arch form and its dimensions. Plaster model analysis is a time-consuming procedure. Dividers, calipers, and Boley gauges have provided the standart of measurement against which newer methods have been evaluated [1]. Various scanning techniques, including laser scans, structured light, de...

introduction: foreign body aspiration (fba) represents a life-threatening emergency .it occurs primarily in children below 3 years. generally, the most common aspirated fb is organic material such as nuts or beans. sharp foreign bodies (fbs) are of particular concern to the attending clinician, because of their potential to perforate the air passage and cause possible complications. here in, we...

An expert group of 40 pain specialists from 16 countries performed a first assessment of the value of predictors for treatment success with 5% lidocaine-medicated plaster in the management of cancer pain with neuropathic components and trigeminal neuropathic pain. Results were based on the retrospective analysis of 68 case reports (sent in by participants in the 4 weeks prior to the conference)...
