Perioceutics promote growth of which tissue?

• A. Growth of junctional epithelium
• B. Bone regeneration
• C. Healing of gingiva
• D. Regeneration of cementum

Answer: (A)

Perioceutics are local therapies designed to boost periodontal wound healing by delivering agents directly to the site to influence early tissue responses. The tissue that grows first and fastest during healing after periodontal injury is the junctional epithelium. This epithelial layer rapidly migrates along the tooth root to reestablish a seal that protects underlying tissues from bacteria and helps stabilize the wound. Because JE formation is the earliest and most predictable step in healing, perioceutics focus on promoting this epithelial growth to achieve quick and effective closure of the pocket. While bone and cementum regeneration are important for long-term periodontal regeneration, they occur later and are more complex, so the primary targeted tissue by perioceutics is the junctional epithelium.
