Non-surgical Treatment of a Non-vital, Immature Permanent Tooth with a Large Periapical Abscess: A Case Report with 8-month Follow-up

Aim: The purpose of this case report is to present a non-surgical treatment of a non-vital immature upper central incisor with a large periapical abscess within 8 months of follow-up. 
Methods and Materials: A traumatic case was presented in which a paste of calcium hydroxide and iodoform (Metapex®) was placed in the root canal of an immature permanent tooth with a large periapical abscess. Affected teeth were radiographically evaluated periodically over 8 months after paste insertion. At the end of 8 months, this case showed persistent root growth and apexification with no evidence of periapical radiolucency. After that, a normal root canal treatment was performed. 
Conclusion: In this clinical case, calcium hydroxide and iodoform paste (Metapex®) was found to induce apical closure radiographically and clinically. At 8 months, the periapical abscess was shown to have healed with continued root growth.
