The segment of our society over age 65 is growing, and many more of these people are keeping their teeth for a longer period of time. This suggests that there will be additional need for periodontal therapy in the future, but it also implies that disease-related events must be distinguished from age-related changes. Changes in the periodontium with aging are reviewed, and periodontal disease management strategies in the older patient are discussed.

A mathematical model of the periodic, rippled P beta' phase of phosphatidylcholine is described. In this model the P beta' phase shows a periodic variation in membrane properties corresponding to a lateral periodic variation between fluid-like and crystal-like states. The model is based on a curvature-dependent Landau-de Gennes free-energy functional. Our proposed form of the curvature-dependent free energy remedies a subtle mathematical flaw in an earlier model having similar physical content [Falkovitz, M. F., Seul, M., Frisch, H. L. & McConnell, H. M. (1982) Proc. Natl. Acad. Sci. USA 79, 3918-3921].
