P. gingivalis-specific T-cell Lines Produce Th1 and Th2 Cytokines

E. Gemmell, C.L. Carter, D.A. Grieco, P.B. Sugerman, and G.J. Seymour
P. gingivalis-specific T-cells produce both Th1 and Th2 cytokines, regardless of the population of antigen-presenting cells.

Severe Impairment of Secretory Ig Production in Parotid Saliva of Down Syndrome Individuals

S. Chaushu, E. Yefenof, A. Becker, J. Shapira, and G. Chaushu
Individuals with Down Syndrome are immunodeficient in the humoral mucosal immune response, which may partly explain the high incidence of recurrent infections in target organs of the secretory immune system in these individuals.

Reducing Patients' State Anxiety in General Dental Practice: A Randomized Controlled Trial

Y.-M. Dailey, G.M. Humphris, and M.A. Lennon
Providing the dentist with information on the high level of a patient's dental anxiety prior to treatment, and involving the patient in this, reduced the patient's state anxiety.

The Importance of the Level of the Lip Line and Resting Lip Pressure in Class II, Division 2 Malocclusion

B.G. Lapatki, A.S. Mager, J. Schulte-Moenting, and I.E. Jonas
This is the first study to provide evidence that individuals with a Class II, Division 2 malocclusion have maxillary central incisors exposed to significantly higher resting lip pressure than those with Class I malocclusion.

Fluoride Uptake, Retention, and Remineralization Efficacy of a Highly Concentrated Fluoride Solution on Enamel Lesions in situ

W. Buchalla, T. Attin, J. Schulte-Mönting, and E. Hellwig
A single application of highly concentrated fluoride solution increases remineralization.

Comparative Microstructural Study of the Diffusion Zone between NiCr Alloy and Different Dental Ceramics

C. Hegedus, L. Daróczi, V. Kökényesi, and D.L. Beke
It is shown by transmission electron microscopy that, in the reaction processes taking place at the NiCr alloy/dental ceramics interface, nanocrystalline Cr2O3 first forms and amorphous silicon oxide inclusions appear, then, at longer firing times, complex NiCr and NiCrTi oxides form.
