Vicker's microhardness and energy dispersive x-ray analysis of fluorapatite-leucite and fluorapatite ceramics cyclically immersed in acidic agents.
This study evaluated the microhardness and elemental composition of various ceramics immersed in acidic agents. One hundred and five discs of fluorapatite-leucite (IPS d.SIGN) and fluorapatite ceramics (IPS e.max Ceram) were randomly divided into 7 groups of 15 each. Five groups were alternately immersed in acidic agents (citrate buffer solution, pineapple juice, green mango juice, cola soft dr...
متن کاملDegradability of fluorapatite-leucite ceramics in naturally acidic agents.
This study was conducted to evaluate the titratable acidity and effect of naturally acidic agents on the surface microhardness, elemental composition, and surface morphology of fluorapatite-leucite ceramics. One hundred and ten ceramic disks (IPS d.SIGN), 12.0 mm in diameter and 2.0 mm in thickness, were fabricated. Before immersion, the baseline data of Vickers microhardness and elemental comp...

OBJECTIVE The aim of this study was to evaluate the flexural strength of two porcelain materials (IPS d.SIGN and IPS e.max Ceram) exposed to erosive agents. MATERIAL AND METHODS One hundred and twenty bar-shaped specimens were made from each of fluorapatite-leucite porcelain (IPS d.SIGN) and fluorapatite porcelain (IPS e.max Ceram) and divided into 8 groups of 15 specimens each. Six groups we...

متن کاملStructure and substitutions in fluorapatite.
Fluorapatite, Ca10(PO4)6F2. is a widely spread form of calcium phosphate present particularly in biological material. Human hard tissues contain crystals structurally related to apatite. Fluoride can be found in various natural sources and is also used for its beneficial action in caries prevention. Fluorapatite belongs to the spatial group P6(3/m) (C(6h)2) and consists of 3 ions: F-, Ca2+, PO4...
