• Critical reviews in oral biology & medicine

  • Lipopolysaccharide Heterogeneity: Innate Host Responses to Bacterial Modification of Lipid A Structure
    D.R. Dixon and R.P. Darveau
    The authors describe examples of natural lipid A heterogeneity and the mechanisms that control it, representing a novel approach in which bacteria modulate host responses and may thereby confer specific advantages to certain bacterial species under changing environmental host conditions.
  • Drug-induced Disorders of Teeth
    C.J. Tredwin, C. Scully, and V. Bagan-Sebastian
    In this review, the authors classify drugs with the potential to induce changes in teeth such as discoloration, physical damage to tooth structure, and alterations in tooth sensitivity.
  
  

• Rapid Communication

  • Organized Tooth-specific Cellular Differentiation Stimulated by BMP4
    A. Ohazama, A. Tucker, and P.T. Sharpe
    BMP4 has the ability to stimulate organized differentiation of epithelial- and mesenchymal-derived dental-specific cells from non-dental primordia.
  • Transglutaminase Crosslinking of SIBLING Proteins in Teeth
    M.T. Kaartinen, W. Sun, N. Kaipatur, and M.D. McKee
    The authors report the finding of two novel transglutaminase substrates in vivo, DMP1 and DPP.
  • Mouse Amelogenin Exons 8 and 9: Sequence Analysis and Protein Distribution
    P. Papagemkis, J.M. \barra, N. Inozentseva, P. DenBesten, and M. UacDougall
    The authors' data support their hypothesis that AMELX contains 2 additional exons, that ameloblasts and odontoblasts synthesize amelogenin 8/9, and that amelogenin splice variants may have unique functions during tooth formation.
  • NO-cGMP Signaling Molecules in Cells of the Rat Molar Dentin-Pulp Complex
    Y. Korkmaz, M.A. Baumann, D. Steinritz, H. Schroder, S. Behrends, K. Addicks, K. Schneider, W.H.-M. Raab, and W. Bloch
    The authors show localizations of enzyme-soluble guanylate cyclase (sGC) in odontoblasts, nerve fibers, and blood vessels indicating that, at these localizations, sGC mediates the effects of nitric oxide (NO) generated by NO synthase I and III at these sites.
  • Suppression of Stress-induced nNOS Expression in the Rat Hypothalamus by Biting
    N. Hori, M.-C. Lee, K. Sasaguri, H. Ishii, M. Kamei, K. Kimoto, M. Toyoda, and S. Sato
    Paraventricular nucleus neurons play an important role in mediating behavioral responses to stressors.
  • Cleavage of PDGF Receptor on Periodontal Ligament Cells by Elastase
    E. Nemoto, S. Kanaya, M. Minamibuchi, and H. Shimauchi
    Elastase may modulate the PDGF-mediated activity of periodontal ligament cells during periodontal wound healing.
  
  

• Biological (continued)

  • PTH(1 -34) Affects Osteoprotegerin Production in Human PDL Cells in vitro
    S. Lossdorfer, W. Gotz, and A. Yager
    The authors show, for the first time, that PTH modulates the ability of PDL cells to proliferate, differentiate, and produce OPG, depending on the maturation state of the cells and the mode of PTH administration.
  • Regulatory T-cells Infiltrate Periodontal Disease Tissues
    T. Nakajima, K. Veki-Maruyama, T. Oda, Y. Ohsawa, H. Ito, G.J. Seymour, and K. Yamazaki
    CD4⁺CD25⁺ Tr cells and possibly other regulatory T-cell populations do exist and may play regulatory roles in periodontal diseases.
  • Effect of Occlusal Interference on Habitual Activity of Human Masseter
    A. Michelotti, M. Farella, L.M. Gallo, A. Veltri, S. Palla, and R. Martina
    This is the first long-term study investigating the effect of occlusal interference on the EMG activity of the masseter in awake subjects.
  • Validation of the Child Perceptions Questionnaire
    L.A. Foster Page, W.M. Thomson, A. lokovic, and D. Locker
    The construct validity of the CPQ_{n_14} appears to be acceptable
  
  

• Biomaterials & Bioengineering

  • Water Concentration in Self-etching Primers Affects their Aggressiveness and Bonding Efficacy to Dentin
    N. Hiraishi, N. Nishiyama, K. Ikemura, J.Y.Y. Yau, N.M. King, I. Tagami, D.H. Pashley, and F.R. Tay
    In the formulation of self-etching primers, a balance must be achieved to provide sufficient water for adequate ionization of the acidic monomers, without lowering the resin concentration too much, to optimize their bonding efficacy to dentin.
  • Resin Composite Properties and Energy Density of Light Cure
    A. Peutzfeldt and E. Asmussen
    Within clinically relevant power densities, not only energy density but also power density per se have significant influence on resin composite properties.
  • Monomer Conversion of Pre-heated Composite
    M. Daronch, F.A. Rueggeberg, and M.F. De Goes
    Pre-heating composite prior to photoactivation provides greater conversion requiring less light exposure than room-temperature composite.
  • Anode Glow Discharge Plasma Treatment of Titanium Plates Facilitates Adsorption of Extracellular Matrix Proteins to the Plates
    H. Yamamoto, Y. Shibata, and T. Miyazaki
    Anode glow discharge plasma treatment is a promising surface-modification technique for titanium implants.
