asked the Secretary of State for the Home Department if he will publish the report of the Poisons Board arising from their consideration of sodium fluoride in dentifrices and mouthwash tablets.

The proceedings of the Poisons Board are confidential. The Board considered this matter in 1961 and 1962, and in accordance with its recommendations dentifrices and mouthwash tablets containing sodium fluoride may be sold freely provided that they contain not more than 0·3 per cent. and 0·2 per cent. of sodium fluoride respectively.
