Etiology of Dental Caries

Dental caries is a chronic disease affecting millions of people. It involves decay of teeth by affecting the mineralized tissues of the teeth, enamel, and dentine caused by the action of acidogenic bacteria on carbohydrates in the food. The disease is progressive in nature and can expand ultimately leading to complete decay of tooth if left untreated. It can progress to pulp inflammation causing toothache and discomfort. Dental caries is the result of a complex interaction among plaque, host, diet, and time. The rate of secretion of saliva and the composition of saliva affects the development of caries.
