Final answer:
SRP, or scaling and root planing, is a procedure that can reduce probing depth by 1-2mm by removing plaque and tartar and allowing the gums to heal.
Step-by-step explanation:
SRP, or scaling and root planing, is a dental procedure used to treat gum disease. It involves removing plaque and tartar from the teeth and smoothing the root surfaces to prevent further bacterial growth.
After performing SRP, there can be a reduction in probing depth of 1-2mm. This is because the procedure removes the buildup of plaque and tartar, which can lead to inflammation and deepening of the gum pockets. By removing the irritants and providing a clean surface, the gums can heal and reattach to the teeth, resulting in a shallower probing depth.
For example, if a patient had a probing depth of 5mm before SRP, it may be reduced to 3-4mm after the procedure. This reduction indicates an improvement in gum health and a decrease in the severity of gum disease.
