Sir, for the Q ; the best cement that can be used it GIC ( fluoride release, elastic modulus close to dentin & the pH is not acidic). However zinc polycarboxylate can also be used. ( lager molecular wt. & the pH increases in 24h)

Great answer..but you should first think about the type of restoration :)

When the thickness of dentine is more than 1.5 mm ,, it’s okay to use zinc phosphate bcx it will not elicit any pulp sensitivity . On the other hand it’s a good insulator as compared to GIC and zinc polycarboxylate cements
@lisamariecolaco7934 жыл бұрын
Sir for the quiz question - although zinc Polcarboxylate cement can be used at RDT 1.5mm, GIC would be the best option due to its - chemical bonding, high fluoride release, anticariogenic property, elastic modulus very similar to that of dentin, its pH is much more suitable than that of zinc phosphate and slightly better than zinc Polcarboxylate so no worries of any irritation to the pulp

Thank you for your video sir . And for your question- we will use gic if 1.5 mm dentine depth is remaining .. because gic is not a pulp irritant . As compare to zinc phosphate it’s ph is low which cause pulp irritation .
@Aspire324 жыл бұрын
Great. But the anser can be both polycarboxylate and gic because if you just consider pg then polycarboxylate is better. But GIC has other. Benefits like chemical bonding. Hence gic is preferred. The best luting cement js Resin cement :)

Sir, to make an attempt to the quiz.. i feel GIC can be used as a base for 1.5mm of RDT as its ph is not as bad as other cements, also its similar elastic modulus like dentin, releases more of fluoride.
@simranjeetkaurdeol6704 жыл бұрын
Zinc Polycarboxylate ...as pulpal response is less ....after 24hr ph is 5-6 , ...polyacrylic acid has less penetration into the dentinal tubules... Not as good as gic but it has also got fluoride release . .... chemical bonding .
