Degradability 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...
متن کاملVicker'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 کاملFlexural strength of fluorapatite-leucite and fluorapatite porcelains exposed to erosive agents in cyclic immersion
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 کاملeffect of acidic agents on surface roughness of dental ceramics
background: an increase in surface roughness of ceramics may decrease strength and affect the clinical success of ceramic restorations. however, little is known about the effect of acidic agents on ceramic restorations. the aim of this study was to evaluate the surface roughness of dental ceramics after being immersed in acidic agents. methods: eighty-three ceramic disk specimens (12.0 mm i...
