 Background & Aims: It is known that Hertwig's epithelial root sheath and stem cells of apical papilla (SCAP) can organize the odontoblast cells under favorable conditions resulting in continued formation of the root even after the pulp is necrotic. The aim of this case report was to demonstrate the continued development of the roots of an immature permanent tooth with necrotic pulp subsequent to conservative root canal treatment.

 Case report: The patient was an 8-year-old healthy boy with a severe carious lesion in the lower left first molar tooth with an immature root. The tooth underwent a conservative treatment approach, i.e. minimal filling with (k-files: stainless steel, Mani- Japan) and copious 2.5% NaOCl irrigation and then was medicated with calcium hydroxide (U.S.P. Sultan-USA). In this case, after one year developed mature apices was observed without any complication.

 Conclusion: It is hoped that in the future, regeneration and stimulation of normal continued root development in necrotic immature teeth will replace apexification. Procedures and much fewer cases of cervical fractures of the crown and root and improper root/crown ratios will be encountered.
