Micro-organism and cell viability on antimicrobially modified titanium.

29 Sep 2009 When titanium is anodized by discharge in NaCl solution, both antimicrobial activity and osteoconductivity are conferred. The viability of adherent micro-organisms and cells on antimicrobial titanium remains uncertain. We hypothesized that a thin ... Read more...

Triphenylphosphine reduction of saturated endoperoxides.

Sep 2009 Triphenylphosphine reduction of saturated endoperoxides derived from 6,6-dimethylfulvene and spiro[2.4]hepta-4,6-diene in the presence of nucleophiles results in the formation of products that mainly stem from deoxygenation followed by carbocation ... Read more...

Effect of vital tooth bleaching on solubility and roughness of dental cements.

30 Aug 2009 STATEMENT OF PROBLEM: Vital tooth bleaching may affect properties of dental cements used for fixed prostheses. PURPOSE: The purpose of this study was to examine the effect of a combined in-office and at-home bleaching regimen on changes in surface ... Read more...

Technical information about 'Peroxides'

Definition: A group of compounds that contain a bivalent O-O group, i.e., the oxygen atoms are univalent. They can either be inorganic or organic in nature. Such compounds release atomic (nascent) oxygen readily. Thus they are strong oxidizing agents and fire hazards when in contact with combustible materials, especially under high-temperature conditions. The chief industrial uses of peroxides are as oxidizing agents, bleaching agents, and initiators of polymerization. (From Hawley's Condensed Chemical Dictionary, 11th ed)
