Effect of fluoride dentifrice and casein phosphopeptide-amorphous calcium phosphate cream with and without fluoride in preventing enamel demineralization in a pH cyclic study
Abstract Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) complexes are anticariogenic and capable of remineralizing the early stages of enamel lesions. The use of fluoride prevents dentalExpand

Boolean operations on multi-region solids for mesh generation
TLDR
An algorithm for Boolean operations on non-manifold models is proposed to allow the treatment of solids with multiple regions (internal interfaces) and degenerate portions (shells and wires), in the context of mesh generation. Expand

FORCE FORMULATION OF A NON-PRISMATIC TIMOSHENKO BEAM FINITE ELEMENT FOR DYNAMIC ANALYSIS OF FRAMES
This paper presents a force-based Timoshenko beam finite element for the linear dynamic analysis of frames containing members with variable cross-sections. The proposed formulation uses exact forceExpand
Progressive structural deterioration of an endodontic instrument – A preliminary micro-computed tomography study
TLDR
Micro-computed tomography provides an external and internal assessment of the structural integrity of an endodontic test file, and its progressive structural deterioration after repeated use in simulated root canals (resin blocks), until fracture. Expand
