[Experience in preventing dental caries in the children of a city with a low fluorine content in its water].

Examinations of the dental status of 12-year-old children of the same schools of the town of Baranovichi in various years of two decades, from 1970 to 1990, showed an increase in the incidence and intensity of dental caries up to the year 1986. After a program of caries prevention was introduced in 1990, these parameters reduced. Local and systemic prophylactic means were tested and introduced in a complex of prophylactic measures. The best prophylactic effect was attained in children aged 9 administered sodium fluoride tablets since the age of 2 in comparison with the children administered such tablets since the age of 6. Efficacy of fluorine varnish and sealing of fissures on permanent molars with vitacryl was assessed.
