Differences Among Classifying Wisdom Teeth using Panoramic X-rays and Cone-Beam Computed Tomography
An interesting article titled “Is Panoramic Imaging Equivalent to Cone-Beam Computed Tomography for Classifying Impacted Lower Third Molars?” appears in the 2019 edition of the Journal of Oral and Maxillofacial Surgery written by Brasil et al. The article explorers if panoramic radiography is able to give similar results as cone-beam computed tomography (CBCT) for the degree of lower wisdom teeth impaction and when using panoramic radiography if the external oblique ridge is a reliable indicator for the degree of lower wisdom teeth impaction. In the article the authors discuss the Pell and Gregory classification which is used to classify the position of a wisdom tooth and can be used to potentially assess the risks of various complications. The authors state how wisdom teeth are usually evaluated using panoramic x-rays but this technique is susceptible to image overlap, magnification, and distortion, … Read more
