Revascularization: a treatment for permanent teeth with necrotic pulp and incomplete root development

Area of Science:

• Endodontics
• Regenerative Dentistry
• Dental Traumatology

Background:

• Immature permanent teeth with necrotic pulp present treatment challenges, including fracture risk and material extrusion.
• Traditional apexification methods do not strengthen dentin walls.
• Revascularization was previously thought impossible in infected immature teeth.

Purpose of the Study:

• To review literature on regenerative procedures and revascularization in immature permanent teeth.
• To identify current recommendations for indications, medications, and treatment methods.

Main Methods:

• Comprehensive literature search.
• Review of articles on regenerative endodontics and revascularization.
• Analysis of current clinical practices and recommendations.

Main Results:

• Root canal disinfection and stem cell stimulation can induce hard tissue formation.
• Continued root development is achievable through regenerative procedures.
• New hard tissue formation strengthens existing dentin walls.

Conclusions:

• Revascularization offers an improved treatment protocol for immature teeth, enhancing root strength.
• While outcomes are unpredictable, regenerative procedures are superior to treatments resulting in thin, fragile root walls.
• Successful revascularization provides an alternative to extraction and opens doors for further treatment options if needed.
