Vital Pulp Therapy of an Immature Traumatized Permanent Tooth with External Inflammatory Root Resorption, a Case Report

Negar Pourhatami, Safoura Sahebi, Shamseddin Ahzan


External inflammatory root resorption is a serious complication of a dental
trauma, which leads to progressive loss of the tooth structure and destruction of
periodontal tissues. Therefore, it represents a challenge in endodontic practice
especially in cases of young children with incomplete root development.
Vital pulp therapy (VPT) is an appropriate technique in the management
of immature permanent teeth with partial pulp necrosis. This case report
describes the outcome of a successful VPT in an immature traumatized
permanent tooth with concurrent associated partial necrosis and external root
resorption limited to the coronal part of the root in a 7-year-old boy. The tooth
was treated according to the protocol suggested by American Association of
Endodontics (AAE), consisted of disinfecting the root canal system beyond
the resorptive lesion. Afterwards, mineral trioxide aggregate (MTA) was
packed into the coronal portion of the canal and the tooth was restored with
composite resin. The radiographic follow-up at 3 months showed arrest of
root resorption followed by re-establishment of the periodontal space at 6 and
12 months in the absence of clinical symptoms. The satisfactory outcome of
this case suggests that this conservative approach can heal a partially necrotic
pulp and create a favorable environment for continued root development, and
arrest of the resorptive process.
