Reduced Amelogenin-MMP20 Interactions in Amelogenesis Imperfecta

K. Tanimoto, T. Le, L. Zhu, H.E. Witkowska, S. Robinson, S. Hall, P. Hwang, P. DenBesten, and W. Li
The authors describe a model in which the P41T mutation reduces the interactions between amelogenin and MMP20, leading to decreased degradation of amelogenin by MMP20 and resulting in amelogenesis imperfecta.

Effects of Ethanol Consumption on Periodontal Inflammation in Rats

K. Irie, T. Tomofuji, N. Tamaki, T. Sanbe, D. Ekuni, T. Azuma, T. Maruyama, and T. Yamamoto
Chronic alcohol consumption increased periodontal inflammation, oxidative damage, and TNF- production, and had an additive effect on polymorphonuclear leukocyte infiltration and gingival oxidative damage, increasing the severity of periodontal inflammation in a rat ligature model.

Fluoride Uptake by Plaque from Water and from Dentifrice

J.P. Pessan, S.M.B. Silva, J.R.P. Lauris, F.C. Sampaio, G.M. Whitford, and M.A.R. Buzalaf
The use of fluoridated dentifrice is likely to increase plaque fluoride concentrations significantly for up to 12 hrs in areas where the water contains fluoride close to 1.0 ppm, and such concentrations are directly related to calcium concentrations.
