Abstract
Internal resorption (IR) is a progressive process initiated within the pulp space
with the loss of dentin. Although trauma and pulp inflammation/infection are the major
contributory factors in the initiation of IR, all the etiologic factors and the pathogenesis
have not yet been completely elucidated. Cervical external resorption is defined as
a localized resorptive process that commences on the surface of the root below the
epithelial attachment and the coronal aspect of the supporting alveolar process, namely,
the zone of the connective tissue attachment. This report is presented two cases of
root resorption (external cervical resorption and inflammatory IR) in traumatized
teeth where cone beam computed tomography has been used as an important diagnostic
tool. Treatment of external cervical resorption involved endodontics and periodontics.
In case with inflammatory IR, only endodontic treatment was necessary. The postoperative
course was uneventful and a stable clinical outcome was obtained.
