|Orthodontics, as a specialty, must recognize that teeth and jaw structures are connected to other very significant parts of the human body. The improvement of malocclusions means more than just straightening teeth. To give the patient the appropriate treatment, the other parts affected must also be addressed. This certainly contains the TMJs and the upper airway, which need to be brought into physiologic balance when orthodontic treatment is performed.
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.
