[Periodontal regeneration--finally a reality?]

Area of Science:

• Periodontal regeneration
• Biomaterials science
• Tissue engineering

Context:

• Periodontal disease leads to loss of tooth support.
• Surgical regeneration of periodontal tissues has been a long-standing challenge.
• Early research focused on root surface treatment and graft materials.

Purpose:

• To review historical and recent advancements in periodontal regenerative surgery.
• To highlight key findings in enhancing connective tissue regeneration.
• To discuss current and emerging materials for periodontal regeneration.

Summary:

• Progress in periodontal regeneration involves root surface detoxification, use of demineralized bone/dentin matrices for osteoinduction, and chemical treatments like citric acid or tetracycline.
• While animal studies show high regeneration rates, clinical outcomes have been variable.
• Recent innovations include guided tissue regeneration using membrane materials.

Impact:

• Improved understanding of root surface interactions and osteoinductive potentials.
• Development of new biomaterials and techniques for periodontal reconstructive surgery.
• Ongoing research into resorbable membranes, graft materials, and biologic response modifiers promises further clinical advancements.
