The influence of tray space and repeat pours on the accuracy of monophasic polyvinylsiloxane impression.
Aim: While literature demonstrates that the optimum accuracy is obtained with the custom trays, the use of stock trays for elastomeric impressions appears to be popular in general practice. The aim of...Read More
Comparative Evaluation of the Fracture Resistance of Teeth prepared with Rotary System, filled with single Cone Gutta-percha and Laterally Condensed with Zinc Oxide Eugenol and Resin based (AH26) Sealers to that of Resilon.
Aim and objective: To compare the fracture resistance of teeth prepared with rotary system and filled with single cone guttapercha followed by lateral condensation with different sealers like zinc oxi...Read More
A new approach to both 3-dimensional (3D) trueness and precision is necessary to assess the accuracy of intraoral digital impressions and compare them to conventionally acquired impressions.The purpos...Read More
Analysis of Naturally-occurring Radionuclides in Coal Combustion Fly Ash, Gypsum, and Scrubber Residue Samples.
ABSTRACT: Coal combustion residues from coal-fired power plants can be advantageous for use in building and construction materials. These by-products contain trace quantities of naturally occurring ra...Read More

Enchondroma of the hand with a pathologic fracture is generally treated by tumor curettage and bone grafting after the fracture has healed. However, delayed surgery postpones definitive diagnosis and ...Read More
Magnesian limestone is a key construction component of many historic buildings that is under constant attack from environmental pollutants notably by oxides of sulfur via acid rain, particulate matter...Read More
Phosphogypsum (PG), primary byproduct from phosphoric acid production, is accumulated in large stockpiles and occupies vast areas of land. Phosphogypsum is a technologically enhanced naturally occurri...Read More
It has been observed that due to the cheaper cost of dental plaster compared to dental stone, casts on which most of the dental prostheses and appliances were being fabricated in various laboratories ...Read More
Simple design for an aeroplane plaster of Paris splint in the immobilisation of axillary skin grafts.
Artificial teeth are a useful teaching aid during endodontic education. This article describes the development of a simple and inexpensive model that can be equipped with artificial teeth. It shows th...Read More
Accuracy of dies captured by an intraoral digital impression system using parallel confocal imaging.
The purpose of this investigation was to measure the accuracy of digital impressions (DIs) compared to conventional impressions (CIs). Using the iTero system, a master cast was scanned to produce ster...Read More
Holistic approach to dissolution kinetics: linking direction-specific microscopic fluxes, local mass transport effects and global macroscopic rates from gypsum etch pit analysis.
Dissolution processes at single crystal surfaces often involve the initial formation and expansion of localized, characteristic (faceted) etch-pits at defects, in an otherwise comparatively unreactive...Read More
