Influence of Particle Size on DCPD Hydrolysis and Setting Properties of TTCP/DCPD Cement

February 19, 2017
Author(s)
Limin Sun, Laurence C. Chow, Shozo Takagi, Elena F. Burguera, Stanislav Frukhtbeyn
This study investigated the effects of particle size on the hydrolysis reaction of DCPD at pH 7 and 37 C and on the setting properties of a TTCP/DCPD cement. The kinetics of the hydrolysis reaction was controlled by a nucleation and growth mechanism

Biophysical Characterization of Functionalized Titania Nanoparticles and Their Application in Dental Adhesives

February 2, 2017

Jirun Sun, Elijah J. Petersen, Stephanie S. Watson, Christopher M. Sims, Alexander Kassman, Stanislav A. Frukhtbeyn, Drago Skrtic, Meryem T. Ok, Deborah S. Jacobs, Qiang Ye, Bryant C. Nelson
It is demonstrated that carboxylic acid-functionalized titanium dioxide (TiO2) NPs produce significantly higher levels of reactive oxygen species (ROS) after visible light irradiation (400–800 nm, 1600 mW/cm2) in comparison to nonfunctionalized TiO2 NPs

In Vitro and in Vivo Characteristics of Fluorapatite-forming Calcium Phosphate Cements

August 1, 2010
Author(s)
Shozo Takagi, Stanislav A. Frukhtbeyn, Laurence C. Chow, Akiyoshi Sugawara, Kenji Fujikawa, Kidehiro Ogata, Makoto Hayashi, Bunnai Ogiso
This study reports for the first time in vitro and in vivo properties of fluorapatite (FA)-forming calcium phosphate cements (CPCs). The experimental cements contained from (0 to 3.3) mass % of F, corresponding to presence of FA at levels of approximately

Remineralization Effect of a Low-Concentration Fluoride Rinse in an Intraoral Model

April 1, 2002
Author(s)
Laurence C. Chow, Shozo Takagi, Stanislav A. Frukhtbeyn, B A. Sieck, Edward E. Parry, N S. Liao, Gary E. Schumacher, Milenko Markovic
A previous study showed that a sodium hexafluorosilicate-calcium chloride-based two-solution fluoride (F) rinse containing 6 mmol/l of F was more effective than a 12 mmol/l F sodium fluoride rinse in depositing F on tooth surfaces and increasing oral F
