What is the objective of root planning?

The objective of root planing is primarily to achieve a smooth root surface free from bacteria. This process is an important aspect of periodontal therapy, as it effectively removes not only plaque but also calculus and any infected cementum or dentin from the root surface. By creating a smooth surface, root planing enhances the healing of periodontal tissues and promotes reattachment of the gingiva to the root, ultimately helping to reduce periodontal pocket depth and improve overall periodontal health.

While removing plaque is part of the process, the main goal extends beyond just plaque removal; it focuses on ensuring that the root surface is devoid of bacteria that can lead to further periodontal disease. The other options, such as restoring gum tissue or whitening teeth, do not align with the primary aim of root planing, which is to prepare the root surface for optimal healing and support the health of the surrounding gum tissue.
