What thickness is the coronal cementum that is typically removed during root planning?

The correct thickness of the coronal cementum that is typically removed during root planning falls within the range of 16 to 60 microns. This understanding is important because root planing is a procedure aimed specifically at smoothing the root surfaces to facilitate healing and reattachment of periodontal tissues.

During this process, it is essential to remove not only the calculus and bacterial plaque but also the disorganized cementum and any irritants that may be present. The thickness of 16 to 60 microns is considered a critical range that represents the amount of cementum that can be effectively removed without compromising the structural integrity of the root surface.

Removing more than the recommended thickness may lead to the exposure of dentin or other structures beneath the cementum, which can result in increased sensitivity and potential adverse effects on the periodontal attachment. Therefore, awareness of this specific range is vital for achieving optimal clinical outcomes in periodontal treatment.
