A Tribute to Gerald M. Bowers and Robert G. Schallhorn

Abstract

I am privileged to be the guest editor of this issue of Clinical Advances in Periodontics, one that honors two of the greatest clinicians, educators, and scholars in the field of periodontology. It is especially appropriate that we honor Jerry Bowers and Bob Schallhorn together not only because they have collaborated on numerous articles and courses on periodontal regeneration but they also happen to be the best of friends. What I find most remarkable about Jerry and Bob is their impact on our specialty, an impact that transcends time. The articles contained in this issue of Clinical Advances in Periodontics demonstrate firsthand how Jerry and Bob’s research on regeneration continues to influence the way members of our profession practice today and will do so well into the future. Regeneration is, after all, one area of dentistry that we as periodontists can say we “own.”Their contributions to the field of regeneration also apply to dental implants diagnosed with peri-implantitis, a growing area of concern and one in which periodontists should remain in the forefront. Jerry and Bob have left an indelible mark on our profession, and future periodontists will continue to benefit from their work. Remember that Jerry was the first periodontist to look at growth factors for periodontal regeneration. He did this in 19911 when he combined osteogenin with demineralized freeze-dried bone allograft. Furthermore, his histologic evaluation of new attachment studies2,3 proved definitively that regeneration was possible. Almost all of us use combination therapies for guided tissue and/or bone regeneration. Bob Schallhorn and Pam McClain’s landmark article from 19884 continues to influence us when we use techniques to restore lost periodontium or alveolar bone. Most importantly, Bob and Jerry’s work serves as a constant reminder that: 1) the basis for our clinical decisions should be grounded in evidence; 2) adherence to surgical techniques that capitalize on the fundamentals of wound healing is essential to achieve success; and 3) the patient relies on our clinical judgment and compassion. I encourage all of you to meet these two greats at the 99th Annual Meeting of the American Academy of Periodontology in Philadelphia in September. It will be an experience you will not forget. Their enthusiasm for the field of periodontology is infectious. Their service to our chosen profession is something to be emulated. Their contributions to the boarding process and clinical studies, their leadership in the American Academy of Periodontology, and their grooming of the educators who continue to mold our future clinicians and leaders are things for which we owe them a big debt of gratitude. I have been blessed to be mentored by Bob and Jerry, who have shown me how a professional should act. Above all, they are cherished friends. Jerry and Bob, this issue is but a small token of our appreciation. Your students, your colleagues, and your friends will always admire you, and those in your profession will always be indebted to you. I thank all of you who have contributed to this special issue of Clinical Advances in Periodontics. I know that I speak for all of us when I say thank you, Jerry and Bob, from the bottom of our hearts. n
