(+) - Tartaric acid is incorporated into glass-ionomer dental cements to control the setting characteristics. FTIR has been used to examine the cements as they set, and has confirmed previous results that (+)-tartaric acid reacts more readily with the glass than does poly(acrylic acid), thereby delaying the setting of the cement. Subsequently, ions released by the glass become available for reaction with the polyacid, and gelation occurs. (+)-Tartaric acid not only reacts rapidly to yield…

TLDR
It is concluded that, except at very low levels, strontium oxide powder does not improve the properties of glass–ionomer cements, but at higher levels, it was found to decrease the compressive strength.
Biological Effects Review Paper : Role of Aluminum in Glass-ionomer Dental Cements and its
TLDR
Aluminum that enters the body via the gastro-intestinal tract is mainly excreted, and only about 1% ingested aluminum crosses the gut wall, leading to the conclusion that the release of aluminum from either type of glassionomer cement in the mouth poses a negligible health hazard.

A Rheological Study of the Role of Additives on the Setting of Glass-ionomer Cements
The effects of various additives on the setting of the glass-ionomer cement system was studied by means of cone and plate viscometry. The action of (+)-tartaric acid, the most important additive, on
Acid-base complex reactions in resin-modified and conventional glass ionomer cements.
TLDR
Evidence of a delayed acid-base reaction for the resin-modified cement is demonstrated, which levels off after 168 hours of cement mixing, while the complexation reaction of the conventional glass ionomer cement was essentially complete after 24 hours.
A novel acrylic copolymer for a poly(alkenoate) glass-ionomer cement
TLDR
The results showed that the copolymer of HEMA and acrylic acid was a viable poly(alkenoic) acid for formation of glass-ionomer cements.

TLDR
13C NMR spectroscopy of the fluid cement pastes have shown that tartaric acid reacts more readily than the polyacid with the glass, and hence suppresses the premature gelation of the cement.

TLDR
Tartaric acid acts as an accelerator that aids in the extraction of ions from the aluminosilicate glass and facilitates their binding to the polyanion chains.

Water-soluble ions in dental cements of different ages were studied and electrical conductance measurements were made on cements up to three months after formation.
