Classification of periodontal and peri-implant diseases and conditions 2018. Second part

Abstract

The 1999 classification of periodontal diseases was in force for 18 years. In 2017 a world workshop was performed, where periodontal experts from all over the world, with the co-sponsorship of the American Academy of Periodontology (AAP) and the European Federation of Periodontology (EFP), met to update and present a new classification as evidence based on scientific research has expanded. They were divided into four working groups: I periodontal health, diseases, and gingival conditions. II Forms of periodontitis. III Periodontal manifestations of systemic diseases and developmental and acquired conditions. IV Peri-implantdiseases and conditions. This second part will address the main definitions and parameters of group III (Periodontal manifestations of systemic diseases and developmental and acquired conditions), which includes systemic diseases that cause direct damage to healthy periodontal tissues, periodontal abscesses, and endodontic-periodontal lesions, classifying them according to whether or not periodontitis exists. It also considers the change of the term biotype by periodontal phenotype and a new classification of gingival recessions, which evaluates their severity from the interproximal attachment loss. Finally, group IV (Peri-implant diseases and conditions) is also reviewed, describing peri-implant health, peri-implant mucositis and peri-implantitis, and hard and soft tissue deficiencies.
