Which stage demonstrates the highest level of attachment loss?

The stage that demonstrates the highest level of attachment loss is Stage 4. In veterinary dentistry, the classification of periodontal disease typically ranges from Stage 1, which involves initial inflammation and mild attachment loss, to Stage 4, where there is severe attachment loss, often accompanied by significant bone loss and teeth mobility. At this stage, the periodontal structures are critically compromised, and the disease progression has reached a point that may pose a risk of tooth loss.

The assessment of periodontal disease stages is vital for developing treatment plans and determining the prognosis for affected animals. As the stages progress, the extent of tissue damage and the impact on overall oral health become increasingly severe, emphasizing the importance of early intervention and preventive care.
