Dens invagination is a developmental anomaly that required specific treatment approaches. The invagination is truly negligible and enamel-lined for which the crown of the tooth is the only range and there is no extension on the level of the external amelocemental junction. A well ending surgical root canal treatment of an invaginated tooth applied a retrograde filling with MTA is concluded by this study. Periapical radiographic examination after 3 month and 6 year follow-up showed periapical healing with osseous formation.
