What qualifies as stage 3 moderate periodontitis?

Stage 3 moderate periodontitis is characterized by an attachment loss of 25-50%. This stage marks a significant advancement in periodontal disease, where the surrounding support structures of the teeth begin to break down more notably, but not yet to the extent seen in severe periodontitis. At this stage, clients may notice some degree of gum recession, and the condition can lead to further complications if not addressed. The classification system used to identify the stages of periodontitis is crucial for ensuring appropriate treatment strategies and client education, making it necessary to understand the specific thresholds of attachment loss that categorize the severity of periodontal disease.
