HC Deb 16 July 1956 vol 556 c63W
Mr. Viant

asked the Minister of Health the ages of the children at Watford and in the control area whose teeth have been examined in connection with the scheme to add fluorides to the water; whether the same children will be examined each year; and how many children, at each age, have had their teeth examined in connection with the scheme for fluoridation of water supplies in Watford and in the control area.

Mr. Turton

Representative samples of children from Watford and the control area, between 3 and 14 years of age, have been examined. Similar samples, but not necessarily the same children, will be examined at the same time each year. The samples consist of between 100 and 150 children at each year of age.
