Biomimetic Intracanal Reinforcement Using an Autogenous Biological Post in Primary Anterior Teeth: A Clinical Case Re-port.

Background: Severe early childhood caries frequently results in extensive coronal destruction of primary anterior teeth, compromising retention and function. Intracanal reinforcement is often required to enable coronal reconstruction. Biological posts fabricated from extracted human teeth have been proposed as a biomimetic alternative to conventional post systems. Objective : The purpose of this report is to describe the comprehensive rehabilitation of a pediatric patient with severe early childhood caries using a biomimetic intracanal reinforcement approach, including the fabrication and clinical application of an autogenous biological post in primary anterior teeth. Case Presentation: A 5-year-old female patient diagnosed with severe early childhood caries presented with extensive coronal destruction of maxillary primary incisors. Comprehensive rehabilitation was performed, including pulp therapy and intracanal reinforcement. A customized biological post was fabricated from an extracted human tooth obtained from an institutional tooth bank and sterilized according to biosafety protocols. The post was adapted to the canal morphology and cemented using glass ionomer luting cement, followed by composite resin crown reconstruction. Results: Results: The biological post demonstrated satisfactory clinical adaptation, retention, and short-term functional stability. Conclusion: A dentin-derived biological post may represent a viable biomimetic intracanal reinforcement option in severely compromised primary anterior teeth. Further longitudinal and biomechanical studies are required to confirm long-term outcomes.
