mkg-963	Ismiyatin, Kun	Shear bond strength between porcelain and nano filler composite resin with or without 9% hydrofluoric acid etching	2009	4	.pdf	application/pdf	3488	190	48	The result of the reaction, which is H2[SiF6](aq), dissolves, resulting a micro porous porcelain surface.11 The study on the etching of porcelain surface using 9% hydrofluoric acid for one minute produces as wide as 50 μm pore diameter of porcelain surface,12 so that the resins applied to the surface of the porcelain will penetrate into those pores and form resin tag, producing micro mechanical interlocking between porcelain and composite resin. This experiment was done to find out if 9% hydrofluoric acid etching on porcelain surfaces would cause an increase in the composite resin’s shear bond strength towards the porcelains without acid etching.	cache/mkg-963.pdf	txt/mkg-963.txt
