Periodontal and peri-implant diseases and conditions: New classification

A new global classification system for periodontal health, diseases and conditions, as well as peri-implant diseases and conditions, has been announced at the EuroPerio9 congress, the world’s leading congress in periodontology and implant dentistry.

The comprehensive classification was based upon the most contemporary evidence and includes a staging and grading system for periodontitis, indicating severity and extent of disease, accounting for lifetime disease experience and taking into account the patient’s overall health status. The complete review and consensus reports are published simultaneously in both the Journal of Clinical Periodontology (EFP) and the Journal of Periodontology (AAP).

This was a huge undertaking but one of vital importance, ensuring that an international language for clinical care, research and education is established, and updating the 1999 classification system to account for rapid advances in scientific knowledge over the last 20 years,” said Iain Chapple, EFP Secretary General and Co-Chair of Group 1 of the workshop.

The new classification is the outcome of a joint workshop held by the European Federation of Periodontology and the American Academy of Periodontology in Chicago in November 2017. The workshop included over 100 experts from Europe, America, Australia and Asia who reviewed existing literature to create a global consensus that enables care to be standardised for patients around the world.

In the new classification, clinical health is defined for the first time and periodontitis is described in four stages, ranging from Stage 1 (least severe) to Stage 4 (most severe). The risk and rate of disease progression has been categorised into three grades from lowest risk of progression (Grade A) to the highest (Grade C). The grading considers risk factors such as smoking and the presence of concomitant diseases, such as diabetes.

The new classification should provide a globally consistent approach to diagnosis and management and ultimately improve outcomes for our patients,” said Prof Chapple.

Next steps include careful education of the Oral Healthcare team to ensure its simplicity is recognised as, at first glance, the classification may appear complex but it is actually quite pragmatic, and to make sure we train effectively in its implementation,” concluded Prof Chapple.

About the EFP

The European Federation of Periodontology (EFP) is an umbrella organisation of 30 national scientific societies devoted to promoting research, education and awareness of periodontal science and practice.

It represents more than 14,000 periodontists and gum-health professionals from Europe, northern Africa, and the Middle East.

About EuroPerio9

EuroPerio is the world’s biggest scientific meeting devoted to periodontology. The most recent of these triennial meetings, EuroPerio8, took place in London in June 2015 and brought together almost 10,000 people. EuroPerio9 will take place from 20 to 23 June 2018 at the RAI, Amsterdam, The Netherlands.
