Abstract The last 25 years have brought unprecedented advances to our understanding of periodontal disease. Consider that the 1970 periodontitis was believed to effect most individuals over the age of 35 years, to progress steadily in an individual once initiated until teeth were lost, to be the primary cause of tooth loss in adults, to be caused by the bacterial mass accumulating on the tooth surface and subgingivally, and to involve the host in some fashion or another. In the 25 years since then, impressive research advances in the epidemiology of periodontal disease, the specific bacterial etiology of periodontal disease and the immunoinflammatory mediators of periodontal tissue destruction have greatly altered our view of periodontal disease. Thus, given these research advances in the understanding of periodontitis, what may the future hold for improved diagnosis and treatment of periodontal disease1 Impressive research into new ways to diagnose the periodontal diseases is well underway. Investigators are seeking new ways to diagnose an individual's degree of risk for periodontal disease initiation, susceptibility to disease progression, level of disease “activity” and the likely response to treatment and recurrence of active disease. New diagnostic tests should greatly advance our ability to more accurately and specifically diagnose periodontal disease. The future also looks promising for new treatment strategies to slow or arrest periodontal disease progression. The bacterial specificity of periodontal disease etiology revealed since 1970 has logically led to the use of antibiotics in periodontitis treatment. In the late 1980s the concept of locally delivering antibiotics to the periodontal pocket was introduced, and subsequent clinical trials have indicated that it is possible to reduce pocket depth and inflammation with tetracycline locally delivered to the periodontal pocket. Likely, we have barely scratched the surface in studying the efficacy of locally delivery antimicrobial agents to alter the progression of periodontal disease. As new agents are developed and better delivery systems to the periodontal pocket are developed, the future should see a variety of antimicrobial agents available which can slow periodontal disease progression. The future also holds promise for slowing periodontal disease progression by blocking inflammatory pathways important in periodontal tissue destruction. Clinical trials of flubiprofen, naproxen and ketoprofen indicate that it is possible to slow periodontal disease progression with non‐steroidal anti‐inflammatory drugs which inhibit one destructive pathway. In addition, data from animal models indicate that chemically modified tetracycline as an inhibitor of couagenase can slow disease progression in animals. Again, we have likely only just begun to explore the wide range of molecular mediators of tissue destruction which may be targeted for blocking and thereby slow or arrest periodontal disease progression. Last, research into regenerating periodontal structures lost as a result of disease has had a noteworthy record of progress m the past 25 years. Techniques that utilize bone grafts, root treatments, tissue guiding membranes or polypeptide growth factors have ably indicated that it is possible to regenerate new attachement structures in humans. As investigators continue to unravel the mysteries of the embryonic development of the periodontium. the ability to predictably regenerate lost periodontal attachment structures holds great promise for the future.
