#1
Front (Question)

how are glass ionomers cured?

Back (Answer)

light cured

#2
Front (Question)

what is the thermal conductivity and diffusivity of glass ionomer liners

Back (Answer)

lower than dentine

#3
Front (Question)

what is the compressive strength for glass ionomers?

Back (Answer)

> 170MPa which is higher than ZnO based materials

#4
Front (Question)

what can glass ionomer seal which no other material can seal?

Back (Answer)

dentinal tubules

#5
Front (Question)

what is released from RMGICs which are cytotoxic and effective against residual cavity bacteria?

Back (Answer)

benzoyl iodides and benzoyl bromides

#6
Front (Question)

when should lining materials be used?

Back (Answer)

for cavities in dentine, for amalgam restorations and for larger composite restorations

#7
Front (Question)

when is CaOH used?

Back (Answer)

when the cavity approaches the pulp

#8
Front (Question)

what does CaOH need to be covered with and why?

Back (Answer)

RMGIC prior to final restoration as it protects the CaOH and prevents dissolution beneath the restoration
