Reviving Immature Permanent Teeth: A Case Report on Regenerative Endodontic Treatment as a Retreatment Option

 Endodontic intervention in necrotic immature
permanent teeth often presents a clinical challenge.
However, with careful case selection, regenerative
treatment can be an effective approach, yielding
favorable outcomes. Nevertheless, there is currently no
consensus on the optimal disinfection protocol or the
method to achieve predictable clinical results in
regenerative treatment. One of the advantages of
regenerative endodontic treatment is its potential to
stimulate further root development. In cases where
regenerative treatment fails, conventional methods such
as MTA apexification can be considered as an alternative
treatment option. This article presents a case report of
regenerative endodontic treatment in necrotic immature
tooth #21, along with a 24-month follow-up review,
showcasing the outcomes of the treatment.
