Dental caries
•Caries is Latin for ‘rot’ or ‘rotten’.
•‘Rotten teeth’ are the signs of a disease
called ‘dental caries’ or ‘tooth decay’.
•In dentistry an individual area of rot in a tooth
is called a ‘carious lesion’.
•A rotten tooth is called a ‘carious tooth’.
•Dental caries or tooth decay is a disease
which occurs in childhood.
Did you know?
• Although tooth decay is often considered to be an
affliction of modern society associated, in particular, with
modern dietary habits, there is evidence that it existed in
ancient times.
• Because of their physical structure and chemical
composition, teeth are often the last remains of
prehistoric man, and fossil deposits have been found
which exhibit signs of tooth decay.
• Dental caries has been identified in the teeth of Egyptian
mummies, in the skulls of ancient Greeks, and in the
remains of Romans in Britain.
Treatment and cure
Caries can be treated by one or more of the following:
• Changing the microflora, using agents such as
chlorhexidine and topical fluoride;
• Reducing the amount of dietary sucrose, by dietary
choice;
• Decreasing the frequency of eating, by dietary choice;
• Adding flouride, particularly through daily application
during tooth brushing;
• Increasing salivary flow, using mechanical stimulation
during vigorous chewing to enhance flow.
‘A clean tooth will never decay’
Preventive measures:
• careful brushing
• flossing
• restricting sugar consumption
• use of flourides
• mouth wash
• Since dental caries is an infectious disease, many
scientists have taken into account the possibility of using
vaccination as a community preventive measures
against it.
