What type of healing occurs after scaling and root planing (ScRP)?

After scaling and root planing (ScRP), the typical healing process that occurs is the formation of a long junctional epithelium. This type of healing is characterized by the reattachment of the epithelium to the root surface, which forms a new, smooth surface that reduces the depth of periodontal pockets.

The long junctional epithelium is formed as the epithelium migrates apically to establish a new attachment at the root surface, effectively sealing off the area from bacterial invasion and promoting a healthier periodontal environment. This healing mechanism is significant because it provides a degree of periodontal health, although it does not restore the periodontal support lost due to disease.

In contrast, complete regeneration with new tissue, granulation tissue formation, and fibrous connective tissue healing involve different processes that may not be as typical following ScRP. While granulation tissue forms in healing wounds, it is not the predominant healing response in the context of periodontal therapy. Fibrous connective tissue healing may occur, but it is less specific to the response seen after ScRP compared to the long junctional epithelium that specifically characterizes the healing in this scenario.
