Abstract: The early symptoms of periodontitis are not obvious, while it always accompanied by severe alveolar ridge defects, tooth drifting, flaring, and even tooth loss in advanced stage. It leads to a heavy burden on the country, society, and patients themselves with high prevalence. In 2018, consensus reports on the Classification of Periodontal and Peri-implant Diseases and Conditions were published by the American Academy of Periodontology (AAP) and European Federation of Periodontology (EFP), which divided periodontitis into four stages and three grades. Subsequently, the EFP has published S3-level clinical guidelines for the treatment of stage Ⅰ-Ⅲ and stage Ⅳ periodontitis. This article will discuss the clinical diagnosis and treatment practice of severe periodontitis based on the 2018 Classification with a case of periodontitis (stage Ⅳ, grade C).

Key words: new classification, severe periodontitis, stage, grade, clinical diagnosis and treatment
