4. Dental
media
timeline

5. Share of 2015 articles

6. Our goal: trace the movement of knowledge
through heterogeneous literatures

7. Discussion of research findings in media
• ~1750 or approximately 6% of articles on 24 blogs, Dr Bicuspid &
DentalTown discuss findings of research articles
• articles containing “journal of”, compendium or “abstract “
• ~ 2.7x other media mentions
• Sources vary:
• 25% or 765 posts on Jablow blog are abstracts of research articles
• 11% or 572 articles on Dr Bicuspid discuss research articles
• 41% or 198 posts on Dental Dude blog discuss research articles
• No lag
• media discusses articles the same month they are published or become available
early access

8. Case study – cone beam computed
tomography (CBCT)
Year Milestone
1972 Computed tomography discovered
1979 Nobel prize
1980s-90s The math years
1994 1st CBCT scan, Italy
1996 NewTom introduced, Italy
1998 1st dental paper:

11. Guidelines discussion: another interaction
with research

12. Topic model of CBCT media discussion

13. Topic model of research literature
source Hicks’ classifying abstracts

14. Topic overlaps
Research
literature
Professional media

15. Conclusions
• Professional media are symbiotic with the scholarly literature
• A lot of media posts draw on journal articles
• Topics are similar, with professional media emphasizing
contextualization and journal articles emphasizing technical precision
• Future work – hierarchical topic model across heterogeneous
literature and discourses to develop metrics of this interaction
