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

Abstract

Aim: To evaluate the clinical and radiological results of a revascularization treatment done in a nonvital, immature permanent tooth using the amniotic membrane. Case description: A 12-year-old boy reported with a complaint of pain in the lower left back tooth since 1 month due to dental caries. On clinical examination, the mandibular left second premolar was tender on percussion and discolored due to dental caries. Radiographic examination of the same tooth revealed open apex, thin root dentinal walls, and periodontal ligament widening. An access opening was prepared, necrotic pulp extirpated completely followed by thorough irrigation. After drying the canal, closed dressing with the 3-mix antibacterial paste was given for 15 days. After 15 days, the paste was removed and the amniotic membrane was placed inside the canal extending 1 mm beyond the apex and mineral tri-oxide aggregate was placed over this followed by sealing of the cavity. The patient was followed up at 1, 3, and 6 months for clinical and radiographic evaluation. Conclusion: After 6 months, clinically the tooth found asymptomatic. Radiographic examination showed continued root elongation, closure in the periapical opening, thick root dentinal walls with narrowing of the canal space, and normal periradicular architecture. Clinical significance: Amniotic membrane can be used as a scaffold for revascularization in nonvital immature teeth.
