In the context of periodontal treatment, what happens if cementum is not removed during subgingival instrumentation?

In periodontal treatment, particularly during subgingival instrumentation, the removal of cementum is crucial for effective healing and reattachment of periodontal tissues. If cementum is not adequately removed, it can interfere with the healing process.

Specifically, residual cementum can harbor bacteria and toxins, which may contribute to ongoing inflammation and prevent the formation of a new and healthy attachment of the periodontal tissues to the root surface. This situation hinders the body’s natural ability to heal and can lead to further periodontal issues, such as pocket formation or attachment loss. Thus, the absence of effective cleaning of the root surface can significantly impede tissue reattachment.

This concept highlights the importance of thorough subgingival debridement in periodontal therapy to ensure optimal healing conditions and support the reattachment of healthy periodontal tissues.
