Uji Kedalaman Porositas Permukaan Bahan Pit dan Fissure Sealant Berbasis Resin Komposit dan Ionomer Kaca Setelah Direndam Saliva Buatan pH 5,5
ABSTRACT: Salivary pH between
5.6 to 7.0 in a normal state. pH below 5.5 included in environments susceptible
to caries. Concentration of H+ ions which will outline the high Ca-P bond and
will liberate ions into the surrounding environment. So that the material of
fissure sealant will lose inorganic mineral constituent and formed on the
surface porosity materials. If the sealant surface rough for their porosity can
be a retention of plaque and calculus that may cause caries. Other than that,
more porosity will affect the compression strength of the material used for
fillings when chewing. Purpose. This research purposed to determine the depth
of surface porosity difference between pit and fissure sealant materials based
resin with glass ionomer after artificial saliva soaked with a pH of 5.5.
Method. This research was a laboratory experimental research design with the
post test only control group design. The total number of samples required were
16 samples. The tool used a Scanning Electron Microscope (SEM) with units of
measurements µ m. Results. The average depth of the material surface porosity
pit and fissure sealant resin-based composite of 2.805 μm, while the glass
ionomer amounted to 1.912 μm. The surface material pit and fissure sealant
resin composite-based artificial saliva soaked with a pH of 5.5 for 24 hours
had a depth porosity greater than the surface material pit and fissure sealant
glass ionomer-based.
