The object of this study was to investigate the relationship between the staining behavior of the carious dentin by the caries detector solution and the structural characteristics of the dentin. Using 160 human extracted caries teeth, the ground and polished sectioned surface and the cutting surface of the caries cavities were prepared. The surface stained by the detector solution was examined ...

This clinical report describes the fabrication of a sectioned mandibular complete denture for a patient with severe microstomia. Dovetails were created in the denture base to orient and secure the prosthesis.

To apply the method of quantitative electron microscopy to the measurement of mass in thin sections, the thickness of the section at or very near the structure to be studied must be known. Dowex anion exchange resin AG 1 x 2, stained with phosphotungstic acid (PTA) at pH 6.4, was used as a thickness standard which could be embedded and sectioned. The sectioned PTA-Dowex appeared uniformly stain...

INTRODUCTION This study was carried out to investigate calcific tissue formation against mineral trioxide aggregate (MTA) after pulp capping. MATERIALS AND METHODS The pulps of six teeth from four dogs were exposed and capped with MTA. After extraction each tooth was sectioned into halves. Each half was then further sectioned in the mesiodistal or buccolingual direction. Calcified tissue of t...

We assessed the effects of various dietary conditions on the growth, phenotypic traits, and morphometric dimensions of rock bream, Oplegnathus fasciatus and on the morphometric dimensions of sectioned olive flounder, Paralichthys olivaceus. Rock bream in the fed group increased in body weight, standard length, and condition factor, but these parameters decreased significantly for fish in the st...

AIMS To evaluate two detailed step sectioning protocols for sentinel lymph nodes (SLNs). METHODS After vital dye or combined dye and radiocolloid guided biopsy, SLNs were fixed in formalin and embedded in paraffin wax. In protocol A, SLNs from 123 patients were sectioned in steps of 50-100 micro m, whereas in protocol B, SLNs from 123 patients were sectioned at steps of 250 micro m. Epithelia...

Structured illumination (SI) has long been regarded as a nonquantitative technique for obtaining sectioned microscopic images. Its lack of quantitative results has restricted the use of SI sectioning to qualitative imaging experiments, and has also limited researchers' ability to compare SI against competing sectioning methods such as confocal microscopy. We show how to modify the standard SI s...
