Abstract
A known procedure is used to prepare liposomes of bipolar lipid membrane which are permeable and hence 'leak' their contents at a rate which is variable by choice. The liposome is supplied with medication or cosmetic material for the oral cavity, or specifically for the teeth and gums. The liposome is then attached to a molecule that has affinity for the hydroxyapatite. Thus, the liposome will bind to oral cavity hydroxyapatite and bathe the surrounding support surface with its contents for extended hours of service.
