Study Notes

Role of Lipids in Oral Health

Lipids in cell membranes of the oral environment determine elasticity, fluidity, and permeability of the cell membrane, and participate in intercellular transport and signal transduction pathways between salivary glands and other tissues.

Lipids in Saliva

Lipids are main components of saliva, and their properties and number vary according to physiological and pathological conditions.
In chronic periodontitis, caries, and calculus, the amount of lipids in saliva increases.

Lipids and Oral Diseases

Oral microbes, such as Porphyromonas gingivalis, one of the main bacteria causing periodontitis, cause negative effects.
Lipids in tooth enamel and dentine, particularly cholesterol and triglycerides, are naturally present in normal dentine.

Lipids and Caries

Saliva of people with caries contains more lipids, particularly neutral and phospholipids, than those without caries.
Lipids increase glucoseyltransferase enzyme activity, enhancing the cariogenic potential of oral microorganisms.
