Accuracy and applicability of periodontitis risk assessment tools: A critical appraisal

Abstract

AbstractCurrently, periodontal risk assessment finds application at first visit (to identify individuals at high risk of either disease incidence, if still healthy, or disease progression, if already diseased) as well as at patient monitoring after active treatment and enrolment in a supportive periodontal care program. Although the current case definition of periodontitis embeds a prognostic determination (ie, periodontitis grade) that showed a predictive value for periodontitis‐related tooth loss, some limitations of periodontitis grade call for the implementation of different risk assessment tools in clinical practice. For some of these, significantly higher accuracy in predicting tooth loss during supportive periodontal care was reported compared with periodontitis grade. Validated periodontal risk assessment tools may be functional to obtain greater adherence to the suggested preventive and treatment protocols, improve oral hygiene performance, and tailor supportive periodontal care. Interestingly, periodontal risk can also be informative of the risk of peri‐implantitis in patients programmed for implant placement or rehabilitated with dental implants. A critical appraisal on the rationale behind risk assessment and the balance between the advantages and limitations of exercising risk assessment in periodontology is presented.
