Abstract

Thirty human non-carious specimens were used in this in vitro study. The specimens were divided into three groups of 10 each: Group 1: incremental fill: Group 2: Beta-Quartz glass-ceramic inserts: Group 3: pre-cured resin composite inserts. All restorations were placed with TPH resin composite. The specimens were thermocycled and sectioned. Microleakage was determined on a scale of 0 (no microleakage) to 5 (microleakage extending to the axial wall). Results of the study indicated that Beta-Quartz glass-ceramic inserts and incrementally placed resin composite restorations exhibited significantly less microleakage compared to pre-cured resin composite inserts (P < .03, Chi-Square Test).

Thin foil preparation of metal particles in brittle ceramic matrices.

Thin foil preparation for metal particles in brittle ceramic matrices is particularly difficult, due to differential thinning of the component materials. This paper considers the preparation of thin foils of stony meteorites. Stony meteorites have a composite nature consisting of small metal particles (< 200 microns) embedded in an inherently brittle silicate matrix. Specimens of this type are difficult to prepare as thin foils because the area of interest is limited to specific regions within the metal particles. The problems of thin foil preparation of metal particles in the stony meteorites were overcome by developing a technique involving electrochemical polishing prior to ion beam thinning. The metal particles were first separated from the silicate matrix and then embedded in Epo-Tek H20E silver epoxy. This specific epoxy was selected for its good electron conductivity which allowed the specimen to be thinned by the electrochemical polishing technique. Specimens prepared by this technique have permitted the direct observation and characterization of the metallic phases in stony meteorites.

Three-dimensional magnetic resonance microscopy of materials.

Several aspects of magnetic resonance microscopy are examined employing three-dimensional (3D) back-projection reconstruction techniques in combination with either simple Bloch-decay methods or MREV-8 multiple-pulse line narrowing techniques in the presence of static field gradients. Applications to the areas of ceramic processing, catalyst porosity measurements and the characterization of polymeric materials are presented. The focus of the discussion centers on issues of sensitivity and resolution using this approach compared with other methods. Advantages and limitations of 3D microscopy over more commonly employed slice selection protocols are discussed, as well as potential remedies to some of the inherent limitations of the technique.
