Localised Aggressive Periodontitis
Also written as: LAP — Localised Aggressive Periodontitis
A now-superseded diagnostic category describing rapid, localised periodontal destruction typically affecting first molars and incisors in otherwise healthy young individuals.
Full Definition
Localised aggressive periodontitis (LAP) was previously used to describe a distinct clinical entity characterised by rapid alveolar bone loss concentrated at the permanent first molars and incisors, often in adolescents with minimal plaque deposits, and frequently associated with Aggregatibacter actinomycetemcomitans infection. The 2017 AAP/EFP Classification eliminated the category of aggressive periodontitis, incorporating these cases into the general periodontitis classification with appropriate staging and grading. Editors must recognise that documents using LAP or 'aggressive periodontitis' as diagnostic terms are using pre-2017 terminology and should annotate accordingly. The abbreviation LAP should be defined on first use.
Usage
Usage note: Flag as superseded nomenclature in any document post-dating the 2017 AAP/EFP classification. The preferred current classification is Stage/Grade periodontitis.
