book based on reviewing published articles like this book is a typical example of evidence-based learning—EBL. The evidence-based literature review can provide foundation skills in research-oriented bibliographic inquiry, with an emphasis on such review and synthesis of applicable literature. All information is obtained from numerous sources provided by scholars and researchers who are involved in various disciplines. Available sources possess a variety of features, especially the degree of reliability. There is a known rank of reliability for evidence sources, which is particularly important in medicine and dental fields (from the most to least reliable evidence source): (1) clinical reports using placebo and dou- ble blind studies, (2) clinical reports not using placebos, but conducted according to well-prepared statistical test plans, (3) study reports on time effect on one group of patients, (4) study reports, at one limited time, on many groups of patients, (5) case reports on a new technique and/or idea, and (6) retrospective reports on clinical evidence.
