Dental fluorosis is an enamel defect caused by extreme fluoride intake during the period of enamel development, leading to incomplete crystal growth and increased absorbency. Dental fluorosis is the first visible sign indicating that much fluoride has poisoned the whole body. Beside the health dangers there are other opposing effects of dental fluorosis such as high costs of other medical and dental difficulties and the effect on the victims and their loss of time.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
