Pulpal response to pyruvic acid

Journal of Oral Pathology & Medicine, 1977
Abstract. Etching of enamel surfaces produces a marked increase in the bond strength of dental materials to tooth structure. The results of recent studies have indicated that pyruvic acid may be used in preference to phosphoric acid, because of its milder etching effect on enamel surfaces, without adversely affecting the bond strength.

Biotechnological production of pyruvic acid

Applied Microbiology and Biotechnology, 2001
Pyruvic acid is an important organic acid widely used in the chemical and drug, as well as agrochemical, industries. Compared with the chemical method, biotechnological production of pyruvic acid is an alternative approach because of the low cost. An overview of biotechnological production of pyruvate, including direct fermentative production employing

Pyruvic acid as an etching agent

Journal of Oral Rehabilitation, 1976
SummaryPhosphoric acid at different concentrations has been extensively used as an etching agent to improve bonding of dental materials to enamel surfaces. Recently attention has been drawn to the possible use of polyfunctional organic acids as conditioning agents.The object of this investigation was to determine the optimal concentration of pyruvic ...

Pyruvic Acid Dimethylhydrazone. A Synthetic Equivalent of the Pyruvic Acid Dianion

Chemistry Letters, 1990
Abstract The pyruvic acid dimethyl hydrazone can be easily prepared in ether. This compound, after deprotonation with alkyllithium, forms a strong nucleophile which on treatment with electrophiles and acidic work up yield α-ketoacids, α-hydroxybutenolides or α,γ-diketoacids.

Pyruvic Acid Peels for the Treatment of Photoaging

Dermatologic Surgery, 2004
Pyruvic acid (CH3-CO-COOH), an alpha-keto-acid, has been recently used as a medium chemical peeling agent in subjects with inflammatory acne, moderate acne scars, greasy skin, actinic keratosis, and warts.The aim of our study was to evaluate the efficacy and tolerability of 50% pyruvic acid on moderately photodamaged facial skin.We treated 20 patients ...
