Setting Change of Amalgam Surface Observed by Scanning Electron Microscopic Motion Picture

Retrograde amalgam filling: a scanning electron microscopic study.

Observed by Scanning Electron Microscopy

The strain of P. aeruginosa used was a Fisher serotype 3,7, originally isolated from a patient with severe burns. The susceptibility of the strain to antibiotics used singly and in combination was determined by the tube dilution method (12). Minimal inhibitory concentrations (MICs) were determined by observing the lowest dilution of antibiotic that prevented visible growth of an inoculum of 105...

Topographic Effects of Four Different Beverages to Cu - Sn ( Eta Prime ) Phase Amalgam Surface : A Scanning Electron Microscopic Study

In this study the corroding and/or tarnishing implications of coke, a fizzy soft drink, tea and coffee to the eta prime phase plastic amalgam surface following the filling were evaluated. Thirty six acrylic blocks were prepared which each one was having 5 mm in diameter and 1 mm in depth welts where condensed with amalgam. Those blocks were divided into six groups. The groups were coffee, tea, ...

Light and scanning electron microscopic study of the lingual structure in the budgerigar (Melopsittacus undulatus)

BACKGROUND: The tongue, which plays a very important role in food intake by vertebrates, exhibits significant morphological variations that appear to represent adaptation to the current environmental conditions of each respective habitat. OBJECTIVES: The aim of the present investigation was to investigate lingual structure in adult budgerigar. METHODS: Tongues of 12 adult budgerigars were used ...

Scanning electron microscopic observation of morphological modifications produced by Fluorostom on enamel surface.

UNLABELLED In this in vitro study, examination of the morphological changes of enamel surface after topical application of a sodium fluoride solution was performed. Validation of the Fluorostom effectiveness became possible, after 10 years of using for the caries prevention national program. MATERIALS AND METHODS Sound human enamel sections, ware treated with a 0.05% sodium fluoride solution....
