Propanedioland Glycerol Derivatives
Thegroup of propanediol and glycerol derivatives includes several traditionalagents, most of which are used as centrally acting muscle relaxants. They have,however, many effects in common with benzodiazepines. Meprobamate, apropanediol carbamate, was considered the agent of choice for the treatment ofanxiety in the mid-1950s. Withthe discovery of the addictive properties of this compound and theintroduction of benzodiazepines, its popularity declined rapidly…

VARIABLES THAT AFFECT HYGROSCOPIC EXPANSION
The magnitude of the hygroscopic setting expansionof a dental investment is generally proportional to the silica content of theinvestment, other factors being equal. The finer the particle size of the silica, the greater isthe hygroscopic expansion. In general, α-hemihydrate is apt to produce a greater hygroscopicexpansion in the presence of silica than is the β-hemihydrate, particularlywhen the expansion is unrestricted.
A dental investmentshould have enough...
