What is calculus not considered in periodontal disease?

Calculus, also known as tartar, is a mineralized plaque that forms on teeth and is significant in the context of periodontal disease. However, it is not considered a disease itself. Instead, it serves as an accumulation that facilitates the environment for periodontal pathogens to thrive, contributing to disease development. Periodontal disease encompasses a range of inflammatory conditions affecting the supporting structures of teeth, and while calculus is a contributing factor, it is not classified as a disease in its own right.

By distinguishing calculus from being a disease itself, it becomes clear that its role is more about contributing to the disease process rather than being the root of the disease. This is essential for understanding the nature of periodontal disease and the need for effective dental hygiene practices to manage calculus formation and maintain periodontal health.
