If we want to make a systematic review on whether there is a relation between third molar impaction and late lower arch crowding , we raise the question : Is there a relation between them ?
Then we determine inclusion and exclusion criteria of papers that we are going to collect. They must be relevant to our topic. If articles found during our search has not matched our inclusion criteria ; they are ignored to others that match.
Then we organize data in tabular forms and analyze their results.
Analysis can summerize the net conclusion of whether they support or refute presence of any relation between molar impaction and lower arch crowding. Continue reading How Systematic reviews are conducted?
