Objective
The aim of the study was to review all cases referred for cone beam computed tomography
(CBCT) to the department of dental radiology at the Leeds Dental Institute to aid
diagnosis of root resorption associated with impacted canines. We aimed to establish
if referral for and reporting of these CBCT assessments were in compliance with current
guidelines. In addition, we introduced a new and innovative tool to aid reporting
of CBCT images of root resorption associated with an impacted tooth. All plain film
radiographs taken before CBCT were reviewed to determine if root resorption was evident
or suspected from the plain film radiographs.
Study Design
Root resorption was recorded from plain film radiographs taken before CBCT by using
a resorption scale designed by the authors for assessing root resorption associated
with impacted canines (Two-Dimensional Leeds Resorption Scale). CBCT radiography reports
of all cases were reviewed to identify cases with confirmed root resorption.
Results
All cases referred for CBCT were compliant with guidelines relating to referrals and
reporting.
Conclusions
CBCT provided improved detection rates (63%) of root resorption associated with impacted
canines. The resorption scale developed by the authors (Three-Dimensional Leeds Orthodontic
Root Resorption Target Scale) is intended to address the subjective nature of reporting
of CBCT images taken to assess root resorption associated with impacted teeth.
