Background

Invasive cervical resorption (ICR) is a progressive, dynamic, external inflammatory process. The full extent of this resorptive process is often difficult to establish using 2-dimensional radiographic techniques. Small-volume cone beam computed tomography (CBCT) has become an important tool to evaluate additional factors that influence clinical decisions and outcomes.

Objective

Our objectives were to detect the impact of 3-dimensional evaluation on diagnosis, treatment planning, and prognosis from periapical (PA) radiographs.

Materials and Methods

A total of 27 cases of ICR with matching PA and CBCT images were included in the study. All images were individually assessed by 3 board certified endodontists in a blinded manner. Examiners were required to classify each case based on the Heithersay classification, provide a suitable treatment plan based on their own radiographic interpretation, and estimate a long-term prognosis based on both PA and CBCT assessments done separately.

Results

There was a low to moderate rate of agreement regarding resorption classification, surgical treatment decision, and prognoses, regardless of the imaging modality.

Discussion

The use of CBCT allows for the evaluation of ICR characteristic features and eventually leads to better agreement on diagnosis, surgical treatment decision, and prognosis.
