This investigation highlights the use of infrared microspectroscopy for the morphological analysis of urinary stones. The research presented here has utilized the reXectance mode of an infrared microscope for use in creating chemically speciWc maps of cross-sectioned renal calculi surfaces, precisely showing the placement of renal stone components in a calculus sample. The method has been appli...

PURPOSE The aim of this study was to determine the effect of the acquired pellicle on enamel etching. MATERIALS AND METHODS One-hundred teeth were sectioned in the buccal-lingual direction at the half crown. One-hundred half-crowns were polished with pumice powder and rotating brushes (group B) and one-hundred half-crowns were not polished on the buccal surface (group A). The samples were etc...

This study aimed to investigate the effect of multi-ion releasing paste (MP) on acid resistance enamel surface an extracted human tooth. Five kinds MP were prepared according content (wt%) S-PRG fillers: 0 wt% (MP0, control), 1 (MP1), 5 (MP5), 20 (MP20), and 30 (MP30). The buccal coronal surfaces anterior teeth polished with each kind for min. After removing radicular parts, parts underwent a p...

We investigated single application of pastes containing a surface reaction-type pre-reacted glass-ionomer (S-PRG) filler on enamel demineralization. Human enamel blocks were polished using pastes containing S-PRG filler (0, 5, and 30%) and immersed in demineralizing solution for 5 days with daily change of solutions. The pH measurement and nanoindentation testing was carried out during the imme...

Rice (Oryza sativa L.) grains or seeds are known to lose much of their nutrient and antioxidant contents, following polishing. The current study was undertaken to evaluate and compare the carbohydrate content and antioxidant parameters in the unpolished and polished seeds of three edible indica rice cultivars, namely Swarna (SW), the most popular indica rice cultivar in India and aromatic or sc...

STATEMENT OF PROBLEM Surface of porcelain restoration is a matter of clinical concern because of its abrasive action on the opposing enamel. PURPOSE This study comparatively evaluated wear of enamel when opposed by three different surface finishes of ceramic. MATERIALS AND METHODS A total of 60 metal-ceramic discs (10 mm × 2 mm) with different surface finishes were fabricated. They were div...

INTRODUCTION Patients with onychomycosis may mask infected nails with polish. Tavaborole topical solution, 5% is a boron-based, small-molecule pharmaceutical approved for the treatment of toenail onychomycosis caused by Trichophyton rubrum and Trichophyton mentagrophytes; efinaconazole topical solution, 10% is approved for the same indication. Nail polish appearance after application of tavabor...

AIMS To evaluate the effect of chemical disinfectant on the transverse strength of heat-polymerized acrylic resins subjected to mechanical and chemical polishing. MATERIALS AND METHODS A total of 256 rectangular specimens (65 * 10 * 3 mm) 128 per resin (Lucitone-199 and Acralyn-H) were fabricated. One side of each specimen was not polished and the other was either mechanically (n = 96) or che...

We have compared prospectively the incidence of loosening of 20 femoral stems with a matt surface with that of 20 polished stems of an otherwise identical tapered, non-modular design of Exeter hip replacement. The stems were inserted using the same technique at operation and radiographs showed no difference in the adequacy of the cement mantle or of fixation. All the patients were reviewed regu...
