GENERAL KNOWLEDGE

Detailed explanation-1: -The main source of fluoride is fluoridated drinking water. Fluorine deficiency can lead to dental caries and possibly osteoporosis.

Detailed explanation-2: -Fluoride treatment regimens have been developed to prevent dental caries. Systemic fluoride is easily absorbed and is taken up into the enamel during the period of pre-eruptive tooth formation. The predominant beneficial cariostatic effects of fluoride in erupted teeth occur locally at the tooth surface.

Detailed explanation-3: -Dental caries is a common chronic infectious resulting from tooth-adherent cariogenic bacteria, primarily Streptococcus Mutans, which metabolize sugars to produce acid, demineralizing the tooth structure over time.
