Microstructures and mechanical properties of pure tantalum processed by high-pressure torsion
A body-centred cubic (BCC) structure metal, tantalum, was processed by high- pressure torsion (HPT) at room temperature with different numbers of rotations. The microstructural evolution was studied by electron backscatter diffraction (EBSD).

Dentifrices for preventing erosive tooth wear: An in vitro comparative study
Abstract Erosive tooth wear is a progressive condition that compromises enamel structure and requires preventive strategies. This in vitro study aimed to compare the protective effects of fluoride‐based dentifrices containing various bioactive agents on sound enamel subjected to simulated erosive–abrasive challenges.

Microhardness testing of plastics
Abstract Microhardness measurements have been carried out on polymethyl methacrylate, unplasticised polyvinyl chloride, polypropylene and acetal coplymer using two different test methods. In one case the depth of penetration of a Vickers indenter is measured during application of the load and in the other case the size of the Vickers indent has been ...

Abstract Calcium silicate‐based and glass ionomer cements are often used in caries‐affected dentine. This study investigated the remineralising and physicochemical properties of two calcium silicates and a glass ionomer cement. Human molars with Class I cavities were subjected to pH cycling to simulate caries lesions.
