DNA Hybridization Arrays for Gene Expression Analysis of Human Oral Cancer

R. Todd and D.T.W. Wong
In tumor biology, DNA hybridization arrays are being used for gene/gene pathway discovery, diagnosis, and therapeutic design, and similar applications are advancing our understanding of oral cancer cell biology.

Potentiation of Tumor Necrosis Factor-mediated Apoptosis of Oral Squamous Cell Carcinoma Cells by Adenovirus-mediated Gene Transfer of NF-B Inhibitor

S. Chen, A. Fribley, and C.-Y. Wang
This is the first demonstration that inhibition of NF-{kappa}B by I{kappa}B{alpha} gene transfer sensitizes oral SCC cells to TNF killing.

Contraction Stress Related to Degree of Conversion and Reaction Kinetics

R.R. Braga and J.L. Ferracane
Increased inhibitor concentration reduced curing rate and contraction stress in composites, without compromising the final degree of conversion.

Bonding to Er-YAG-laser-treated Dentin

L. Ceballos, M. Toledano, R. Osorio, F.R. Tay, and G.W. Marshall
The Er-YAG laser creates a laser-modified layer that adversely affects adhesion to dentin, so it does not constitute an alternative bonding strategy to conventional acid-etching.

Dynamic Viscoelasticity of Soft Liners and Masticatory Function

H. Murata, N. Taguchi, T. Hamada, M. Kawamura, and J.F. McCabe
The use of materials with higher loss tangent and shear storage modulus provides the most optimum masticatory function for patients requiring the provision of soft liners on their dentures.

A Novel Mutation in Human PAX9 Causes Molar Oligodontia

S.A. Frazier-Bowers, D.C. Guo, A. Cavender, L. Xue, B. Evans, T. King, D. Milewicz, and R.N. D'Souza
Molar oligodontia is due to allelic heterogeneity in PAX9, and the authors corroborate the role of PAX9 as an important regulator of molar development.

Immunohistochemical Detection of Salivary Agglutinin/gp-340 in Human Parotid, Submandibular, and Labial Salivary Glands

F.J. Bikker, A.J.M. Ligtenberg, J.E. van der Wal, P.A.M. van den Keijbus, U. Holmskov, E.C.I. Veerman, and A.V. Nieuw Amerongen
Salivary agglutinin was distinctly localized in salivary glands, but in distinct glandular secretions, no differences in electrophoretic behavior were observed.

Comparison of Volatile Sulfur Compound Concentrations Measured with a Sulfide Detector vs. Gas Chromatography

J. Furne, G. Majerus, P. Lenton, J. Springfield, D.G. Levitt, and M.D. Levitt
In studies where relatively precise volatile sulfur compound measurements are required, gas chromatography is the preferable technique.

Applying Modern Survival Analysis Methods to Longitudinal Dental Caries Studies

T. Härkänen, M.A. Larmas, J.I. Virtanen, and E. Arjas
Bayesian modeling and data analysis will become familiar features in the dental literature, although the computational burden in estimation is considerably heavier than when traditional frequentist methods are applied.
