ANSWERS
the group of dental materials with a broad range of uses; the highest restrictions
for the material and mixing and handling has the greatest effect on this category
of materials - ANSWER dental cement
how many classifications of caries and restorations are there? - ANSWER VI
used for direct pulp capping. encourages secondary dentin when cavity prep
leaves little dentin or micro pupal exposure. a calcium hydroxide liner. -
ANSWER dycal
