Periodontal diseases are often called as gum diseases or gingivitis. The mildest form of periodontal disease is Gingivitis which is often reversible even with professional treatment. Smoking, aging, genetic predisposition are the factors that contribute gingivitis. Untreated gingivitis leads to periodontitis. Toxins produced by the bacteria irritate the gums which stimulate a chronic inflammatory response and there by the tissues and bone that support the teeth are destroyed. 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.
