In April’s issue of the JDR we see in our lead article a paper by Sillet and co-workers the value of the Eigenfactor (EF) Score in biomedical journal rankings given that EF appears to be a better measure of the prestige of a journal (http://jdr.sagepub.com/content/91/4/329.full ).
The EF does not consider self-citations in the ranking of a journal within a field. Of particular interest in this manuscript is the comparison of dentistry to other medical fields in terms of its “specialized nature” as a medical discipline. When compared to medical fields such as Rheumatology, Pediatrics, Hematology or Cardiovascular systems, Dentistry was demonstrated to be much more specialized in terms of its publication orientation. This group with expertise in the bibliometric area does an excellent job in interpreting this topic for dentistry.
The rapidly developing area of cancer stem cells is nicely highlighted by Krishnamurthy & Nor (http://jdr.sagepub.com/content/91/4/334.full) with a related article on Childhood cancers by Wang (http://jdr.sagepub.com/content/91/4/341.full). Further, a systematic review on key parameters of dental bonding is presented by De Munck and co-workers (http://jdr.sagepub.com/content/91/4/351.full).
Our cover image shows a provocative study on the novel concept of high-frequency acceleration on bone regeneration is demonstrated by Alikhani and co-workers (http://jdr.sagepub.com/content/91/4/413.full).
