Management of Acute Periodontal Conditions—The EFP S2k Level Clinical Practice Guideline

BACKGROUND: The European Federation of Periodontology (EFP) has developed Clinical Practice Guidelines (CPGs) for the treatment of periodontitis and for the management of peri-implant diseases. In accordance with the 2018 Classification, acute periodontal conditions are characterised by rapid-onset pain or discomfort, tissue destruction and infection. Therefore, the development of a CPG to guide patients and clinicians in their management is justified. AIM: To develop an S2k-level CPG for the management of acute periodontal conditions, necrotising periodontal diseases, periodontal abscesses and acute manifestations of endodontic-periodontal lesions. METHODS: This S2k-level CPG was developed by the EFP, following methodological guidance from the Association of Scientific Medical Societies in Germany and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) process. A rigorous and transparent process included synthesis of relevant research in two commissioned systematic reviews, evaluation of the quality and strength of evidence, formulation of specific recommendations and a structured consensus process involving leading experts and a broad base of stakeholders. Recommendations were based on the best available evidence, combined with structured expert consensus, particularly in areas where direct evidence remains scarce. RESULTS: The S2k-level CPG for the management of acute periodontal conditions presents a structured approach, grouping the recommendations in three successive steps: (1) confirming diagnosis, following the case definitions of the 2018 classification; (2) initial treatment, to control the acute condition including pain and active tissue destruction; and (3) subsequent treatments, to manage the pre-existing conditions and prevent the risk of disease recurrence and/or control the potential sequelae. CONCLUSION: The present S2k-level CPG informs clinical practice, health systems, policymakers and, indirectly, the public on the available and most effective interventions in the management of acute periodontal conditions.
