The presence of multiple spaces in the anterior aesthetic zone can produce discomfort for patients and its treatment can be difficult for dental professionals. A variety of treatment options are available and these inclu...

Background: The aim of this in vitro study was to examine the fracture load of composite veneers using three different preparation designs. Material and methods: Fifteen extracted, intact, human maxillary central incisor...

The behaviour of damping and dynamic shear modulus in polypropylene charged with either different volume fraction or size of magnetite (Fe3O4) particles, as a function of the applied magnetic field at 318, 353 and 403 K;...

Dalam praktek sering kali dokter gigi dihadapkan pada pasien yang kehilangan gigi anterior dan ingin segera dibuatkan gigi tiruan karena alasan estetik. Gigi tiruan yang dibuat bisa berupa gigi tiruan sebagian lepasan (G...

CaCO3-epoxy composite coatings containing different qualities of nano-Al2O3 were successfully prepared. Infrared spectroscopy was used to verify whether the nano- Al2O3 was modified successfully and scanning electron mic...

Piezoelectric nanofiber composites of polyvinylidene fluoride (PVDF) polymer and PZT (Pb(Zr0.53Ti0.47)O3) ceramics were fabricated by electrospinning. The micro‐ structure of the PZT/PVDF electrospun nanofiber compo‐...
