Autor: Sandra Handler, Barnet M. Levy, Lee R. Brown, Tommy Wright, Bruce F. Mackler, H.J. Keene, Joanne S. Moylan, Deborah H. Perkins

Publikováno v: Journal of Dental Research. 58:2344-2352

The nature and extent of the immune dysfunctions in 20 immunodeficient patients, as well as the immunocompetence of 22 control subjects, were verified by cell-mediated responsiveness and immunoglobulin quantitations. Comparisons of the microbial comp

Autor: Linda J. Riggan, Sandra Handler, Lee R. Brown, Peggy A. O'Neill, Samuel Dreizen, Deborah H. Perkins

Publikováno v: Journal of Dental Research. 60:10-15

Agglutination titers in 444 saliva and 481 serum samples from 36 head and neck cancer patients and 16 control subjects were determined against formalinized cellular antigens of Streptococcus and Lactobacillus species. Saliva agglutination titers were

Fluoride resistance and adherence of selected strains of Streptococcus mutans to smooth surfaces after exposure to fluoride

Autor: Deborah H. Perkins, Samuel Dreizen, Lee R. Brown, Leonard Graves, J.L. Streckfuss, I.M. Horton

Publikováno v: Journal of dental research. 59(2)

The fluoride resistance and smooth surface adherence characteristics of Streptococcus mutans were examined using tooth model and radioactive cell assays. Resistance to 600 ppmF by S. mutans isolated from the plaque of radiation-induced xerostomia pat

Effects of a single application of sodium fluoride gel on dental plaque acidogenesis

Autor: Samuel Dreizen, Lee R. Brown, J.O. White, I.M. Horton, Deborah H. Perkins, J.L. Streckfuss

Publikováno v: Journal of dental research. 60(8)

Quantitative comparisons of the lactate and acetate produced by human dental plaque in vitro and in situ were made before and after five-minute exposures to 1% NaF gel. Assays included total ionic plaque fluoride by a fluoride electrode, L(+)- and D(
