Prolonged fluorine intake can cause skeletal fluorosis, which may affect teeth, bone tissue and secondarily the nervus sislem. Growth, previous exposure to fluorides, malnutrition, inanition, acid urinary pH, enhance fluorine retention in the body. In subacule and chronic fluorine exposure there are detectable skeletal changes (in the epiphyses of long bones,skull and cervical spine). Cost benefit ratio should be considered when fluorides are prescribed, including the higher susceptibility of children to fluorosis, terotogenecity and the presence of mentioned risk factors. In this country investigations are needed on real needs of fluorine among diferent regional communities, and appropriate knowledge on the concenlralions of fluorine in drugs, tooth pastes, waters and foods is urged before decisions that involve indiscriminated fluoridalion of waters are to be taken.[
