Letter from Noel W Hickey, Fluoridation Committee, Australian Dental Association, Victorian Branch, Toorak to Howard Walter Florey, National University, Canberra Says the association is increasingly concerned at the incidence in dental caries in Victoria - seems that fluoridation is a necessary public health measure - need to convince the public - would welcome Florey's endorsement of fluoridation as safe and effective and a statement on the need for this. 9 October 1964
