Critical Evaluation of the 2017 Classification of Periodontal and Peri-implant diseases and Conditions – An Update

Abstract

Periodontal disease is the multifactorial disease that leads to the destruction of the tooth-supporting structures. A classification system provides a framework that helps in diagnosis and assembles similar disease phenotypes in a more homogeneous form. Several classifications have been proposed by many authors. Till date, the American Academy of Periodontology (AAP) 1999 Classification was the most extensively used classification, which was designed to overcome the drawbacks and deficiencies of the 1989 classification. However, presence of some drawbacks has limited its use in routine clinical practice. So, the current classification has been developed in 2017 by AAP and the European Federation of Periodontology (EFP) to overcome the disadvantages of the 1999 classification. The 2017 classification is extremely extensive and more intricate than 1999 classification, which is useful to the overall dentist and periodontists to select the best treatment options for the patients. This review summarizes the newer classification, key changes from 1999 Classification/modification and disadvantages of the newer classification.
