Abstract

The 2017 World Workshop on the Classification of Periodontal and Peri-Implant Diseases and Conditions introduced a revised framework for the diagnosis and management of periodontitis. A major innovation was the incorporation of grading, designed to supplement disease staging by providing insights into the biological characteristics of periodontitis. Grading reflects the rate of disease progression, anticipated response to therapy, and influence of systemic and behavioral risk factors. Patients are classified as Grade A (slow progression), Grade B (moderate progression), or Grade C (rapid progression), based on clinical attachment loss, radiographic bone loss, and supporting factors such as smoking and diabetes. This system shifts the diagnostic process from a static description of severity to a dynamic model that incorporates risk assessment and future disease trajectory. By integrating both staging and grading, the 2017 classification promotes a more individualized and evidence-based approach to patient care, improving diagnosis, prognosis, and treatment planning in periodontitis.
