Most cases occur during the early stage of the mixed dentition. Specifically, EIRR occurs in approximately 5%-8% of luxation injuries, 30% of replanted teeth following avulsion, and 38% of intruded teeth. Conventional methods for addressing EIRR in immature teeth pose several challenges. This often requires numerous dental visits where Ledermix and calcium hydroxide are used, which may significantly prolong the treatment. Additionally, the effect of prolonged use of calcium hydroxide medication in the root canal is debatable. Recent publications have highlighted the ability of regenerative endodontic treatment (RET) to effectively stop and repair EIRR in a relatively brief time, yielding impressive results. Nevertheless, the underlying mechanism responsible for this effect remains unclear.</p><p><strong>Methods: </strong>A hypothesis is proposed and drawn from existing data, explaining the mechanism by which RET triggers alterations in the root dimensions of necrotic immature teeth, facilitating continuous root maturation.
