In simple words: A severe and fast-acting gum disease that typically affects certain teeth in younger people, causing inflammation and damage to the gums and bone supporting the teeth.

A rapidly progressing form of periodontitis, primarily affecting young individuals, characterized by localized inflammation and destruction of the periodontal tissues supporting the teeth. This typically involves interproximal attachment loss on at least two permanent teeth, one of which is a first molar, and involving no more than two teeth other than first molars and incisors.

Example 1: A 15-year-old patient presents with rapid bone loss around the first molars and incisors, consistent with localized aggressive periodontitis., A 25-year-old non-smoker with no systemic diseases exhibits severe inflammation and attachment loss on two first molars and one incisor, indicating localized aggressive periodontitis., A patient with localized aggressive periodontitis undergoes scaling and root planing, along with antibiotic therapy, to control the infection and halt further bone loss.

Documentation should include clinical findings like pocket depths, attachment loss, bone loss evident on radiographs, and the specific teeth affected.Any relevant family history of periodontal disease or contributing factors like smoking or systemic conditions should also be noted.
