Periodontology: The Past, the Present, the Future

In 2025, the Journal of Periodontal Research proudly celebrates its 60th anniversary. On this occasion, after more than 50 years, we are transitioning to 12 issues per year [1]. Together with this milestone, we introduce one of the exciting initiatives marking the journal's new era: a series of Perspective Articles under the theme “The Past, The Present, The Future”. This series will feature contributions from the “giants” of our field and will serve as a unique opening to each issue of the Journal of Periodontal Research.

The series commences with an insightful contribution from one of the most influential figures ever in periodontology: Professor Jan Lindhe. This manuscript stems from a memorable conversation we shared over tea and biscuits at his home in May 2024. During this magnetic interview, I was transported back in time to relive the pivotal moments that have shaped periodontology, vividly recounted from his extraordinary memory. At the same time, I was struck by his revolutionary mindset, as he continues to challenge established dogmas and share his visionary ideas for the future of our discipline.

I am delighted to share the essence of this unforgettable encounter, which holds a special place in my heart. I hope that this manuscript not only transports readers to that tea-and-biscuits moment, but also ignites a burst of inspiration from the past, present, and future of periodontology.

Journal of Periodontal Research

The launch of the Journal of Periodontal Research in the mid-1960s marked a transformative moment for periodontology. At the time, Dr. Harald Löe—an influential periodontist and researcher—recognized the need for a dedicated journal that would treat periodontology as a research-driven discipline. Unlike the clinical-focused publications of the time, which centered on practical tips and specific geographic areas, this new journal aimed to elevate scientific inquiry in periodontology, positioning the field as a serious, research-based specialty globally. For many years, the Journal of Periodontal Research earned its place as one of the leading journals in dentistry worldwide.

My own career began alongside the Journal of Periodontal Research. My first article as lead author was published in JPR in 1966 [2], the second ever piece published in the journal. Periodontology was still finding its footing then, and at that time, the main focus was on understanding the etiology of periodontitis.
