|Early childhood caries ECC has been observed as one of the most predominant chronic diseases in early childhood. Many studies show ECC was often neglected and most of the decay was left untouched. Early treatment of ECC is significant because untreated caries can lead to pain, sepsis and spreading infection, malnutrition due to the failure to eat, and poor general health. Children with severe ECC or those who are not able to cooperate well for traditional restorative treatment often require general anaesthesia. The cost of dental care is high.
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.
