What does “Aggressive periodontitis (former classification)” mean?
Aggressive periodontitis is a former diagnostic term used to distinguish rapidly progressing destruction of the attachment and bone supporting the teeth. The current international classification describes periodontitis by stage and grade rather than separating chronic and aggressive forms as distinct disease categories.
Relate an old diagnostic name to the current condition
An older record may say “aggressive periodontitis.” That information can help explain the pattern at the time, but it does not replace an assessment of present periodontal health. Current attachment and bone loss, tooth mobility and function are examined to plan treatment.
Assess progression from records and risk factors
When possible, previous periodontal measurements and X-rays are compared to assess change over time. If earlier records are limited, indirect indicators such as bone loss relative to age are considered alongside smoking and diabetes. A sudden feeling of gum pain does not by itself determine the grade.
Plan treatment and ongoing maintenance together
Plaque control, management of risk factors and instrumentation to remove plaque and tartar below the gums are followed by reassessment. If pockets remain, their depth and the form of the lesions guide consideration of repeat instrumentation or surgery that opens the gum to access root surfaces. Maintenance remains necessary, and an old diagnostic label alone does not automatically determine the need for antibiotics or surgery.
Frequently Asked Questions
Is aggressive periodontitis still a separate diagnostic category?
The 2017 international classification combined the former chronic and aggressive categories under periodontitis. The condition is now described using stage, grade, distribution and risk factors.
Does bone loss at a young age always mean aggressive periodontitis?
Age alone is not enough. Current classification and treatment planning consider attachment and bone loss, evidence of progression and risk factors.
