Dens invaginatus: diagnosis and management strategies

Summary:  Purpose: to review the aetiology, classification, diagnosis and management of teeth affected with dens invaginatus. •Developmental dental anomaly where there is invagination of the enamel organ into the dental papilla before completion of calcification; which creates a pocket of organic material underneath enamel surface. •Bacterial contamination and propagation in the irregularity which leads to …
