ABSTRACT
Many studies suggest that uoride may be an essential element for both animals and humans. However, it is true that the essentiality of uoride for humans has not been demonstrated indisputably. Further, data on the minimum nutritional requirement are also inadequate. Incidentally, many epidemiological studies have clearly demonstrated possible adverse effects and health issues that arise due to the continuous ingestion of uoride that is derived mainly through drinking water. These studies clearly show that uoride primarily produces effects on skeletal tissues, especially bones and teeth. However, low concentrations of uoride provide protection against dental caries, especially in children. According to the World Oral Health Report 2003, for a considerable percentage of people, especially children, in most of the industrialized countries, dental decay (dental caries) still remains a major public health issue. The changing living conditions and dietary habits are expected to be reasons for increased incidences of dental decay. Although considerable advancements have been made in preserving and improving global oral health issues, many of such issues related to the poor, marginalized, and disadvantaged groups still persist. Scientic research on the oral health issues related to uoride started more than a century ago and focused on establishing a link between uoride, dental caries, and uorosis. Studies suggest that uoride toothpastes and mouth rinses can signicantly reduce the occurrence and prevalence of dental decay.1
