Revascularization of a Nonvital, Immature Permanent Tooth Using Amniotic Membrane: A Novel Approach

Area of Science:

• Regenerative Endodontics
• Biomaterials in Dentistry
• Pediatric Dentistry

Background:

• Immature permanent teeth with necrotic pulps present a challenge in regenerative endodontics.
• Traditional treatments for nonvital immature teeth often lead to unfavorable outcomes.
• Exploring novel scaffolds for pulp revascularization is crucial for preserving tooth structure.

Observation:

• A 12-year-old patient presented with a nonvital, immature mandibular second premolar exhibiting signs of dental caries and periapical inflammation.
• Clinical and radiographic examination revealed an open apex, thin dentinal walls, and widened periodontal ligament.
• The treatment involved pulp extirpation, antibacterial dressing, amniotic membrane placement, and mineral trioxide aggregate (MTA) capping.

Findings:

• After 6 months, the treated tooth was clinically asymptomatic with significant root development.
• Radiographic evaluation demonstrated continued root elongation, apical closure, thickening of root dentinal walls, and canal narrowing.
• Periradicular tissues appeared normal, indicating successful regeneration and healing.

Implications:

• Amniotic membrane serves as a viable scaffold material for pulp revascularization in immature, nonvital permanent teeth.
• This novel approach offers a promising alternative for managing immature teeth with necrotic pulps, promoting root development and healing.
• The findings support the use of amniotic membrane in regenerative endodontic procedures, potentially improving long-term tooth survival.
