Incorporating New Technologies in Periodontal Diagnosis into Training Programs and Patient Care: A Critical Assessment and a Plan for the Future

N ew diagnostic technologies may be capable of providing the dental practitioner with powerful tools that can assist in the early identification of periodontal disease that can result in expediated treatment. In this paper, clinical, host, and microbiological parameters will be evaluated for their ability to assess disease activity and to assist in the treatment decision‐making process. The discussion will focus on: 1) the perceived need for markers of disease activity; 2) the most commonly proposed markers of disease activity currently under consideration for clinical application; and 3) a plan for future use of disease activity markers. The review concludes that: 1) tooth loss and most forms of rapid disease progression is limited to a small subset of patients within the periodontally diseased population; 2) no single parameter will stand alone as a measure of disease activity; 3) different aspects of treatment may require different combinations of tests to successfully intercept disease in this vulnerable patient group; and 4) early diagnosis can affect long‐term periodontal status. Best estimates are presented for: 1) pre‐disease identification of high‐risk population groups; 2) early diagnosis of disease activity on a site and patient basis; and 3) assistance in the therapeutic decision‐making process. It is further concluded that the complexity of the problem may require a re‐examination of priorities such that more time and money is allocated to early diagnosis as opposed to treatment in this highly vulnerable patient population.
