After scaling and root planning healing occur by:
- A. Long junctional epithelium.
- B. New attachment.
- C. New bone and connective tissue formation.
- D. New attached periodontal ligament fibers.
The most accurate answer to the question "After scaling and root planning, healing occurs by" is: C. New bone and connective tissue formation.
Here's why:
- Long junctional epithelium:
While the junctional epithelium may initially lengthen after scaling and root planning due to inflammation, the goal of healing is actually to shorten it and reattach the periodontal ligament to the tooth root.
- New attachment:
This term is used to describe the reattachment of the periodontal ligament to the tooth root after scaling and root planning. However, it doesn't fully capture the underlying processes involved.
- New bone and connective tissue formation:
This is the most accurate answer because scaling and root planning removes calculus and inflamed tissue, allowing for the regeneration of new bone and connective tissue around the tooth root. This new tissue supports the periodontal ligament and helps to reattach it to the tooth, ultimately leading to a healthier periodontium.
- New attached periodontal ligament fibers:
While new periodontal ligament fibers are formed as part of the healing process, they are a consequence of the underlying bone and connective tissue regeneration, not the primary driver of healing.
Therefore, while all the options have some connection to healing after scaling and root planning, C. New bone and connective tissue formation is the most comprehensive and accurate answer.
