Journal of Dental Research Centennial April 2019: Microbiology of Periodontal Diseases and Dental Caries — A Historical Perspective

Alexandria, VA, USA – 2019 marks the Centennial of the Journal of Dental Research (JDR). Over the last century the JDR has been dedicated to the dissemination of new knowledge and information on all sciences relevant to dentistry and to the oral cavity and associated structures in health and disease.

To celebrate, the JDR is featuring a yearlong, monthly commemorative article and podcast series that highlights topics that have transformed dental, oral and craniofacial research over the past 100 years.

The April 2019 issue of the JDR features the article “The Role of Bacterial Biofilms in Dental Caries, Periodontal and Peri-implant Diseases: A Historical Perspective” by Ana Paula V. Colombo, Federal University of Rio de Janeiro, Brazil and Anne C.R. Tanner, The Forsyth Institute, Cambridge, Harvard School of Dental Medicine, Boston, Massachusetts, USA.

Over the last 100 years, groundbreaking research in oral microbiology has provided a broad and deep understanding about the oral microbiome, its interactions with our body and how the community can impact our health, be protective or lead to the development of dental diseases.

“While the challenges of dental diseases remain as they were 100 years ago, the methods to study them in the clinic and laboratory have evolved dramatically,” said Tanner. “The discovery of DNA and gene sequencing methods has led to powerful culture-independent technologies for analysis of microbial communities associated with dental health and disease. We can now go beyond the ‘one-pathogen one-disease’ paradigm.”

“From checkerboards and microarrays to metagenomics and transcriptomics, using next generation sequencing techniques we’ve learned that dental biofilm is a much more diverse community, composed by species or phylotypes that may acquire and express distinct levels of virulence,” said Colombo. Both investigators further noted that neither caries nor periodontal diseases were single homogeneous infections with differences based in part on variation between individuals and clinical presentations of disease.

The fourth JDR Centennial podcast, titled “The Role of Bacterial Biofilms in Dental Caries and Periodontal Diseases” features a conversation between Colombo and Tanner, moderated by JDR Associate Editor, Nicholas Jakubovics, Newcastle University, England.

Throughout 2019 Jakubovics, will include ‘Historical Highlights’ and archival excerpts from the rich history of research findings published in the JDR. In the April issue, Jakubovics highlights the star paper “Genetic, Nutritional, and Maturational Correlates of Dental Development” [Garn SM, Lewis AB, Kerewsky RS. 1965. Genetic, nutritional, and maturational correlates of dental development. J Dent Res. 44(Suppl): 228-242], which examined correlations between biological and nutritional factors and development of the dentition. Through this long-running, longitudinal, population-based study, Garn, Lewis and Kerewsky found that genetics explained at least 90% of the variation in tooth size, rate of calcification and timing of tooth movement during childhood development.

Along with the article and podcast series, the legacy of the JDR will be honored during a celebration at the 97th General Session of the IADR, held in conjunction with the 48th Annual Meeting of the AADR and the 43rdAnnual Meeting of the Canadian Association for Dental Research, in Vancouver, British Columbia, Canada from June 19-22, 2019.
