Using imaging to assess the impaction of lower wisdom teeth as one ages

by

An interesting article titled “Impaction of lower third molars and their association with age: radiological perspectives,” written by Ryalat et al. appears in BMC Oral Health in 2018 (vol. 18, no. 1, Published April 4, 2018). The article explores the impaction pattern in radiographic images of wisdom teeth. The authors were motivated by the belief that if the impaction patterns of wisdom teeth can be identified this can help guide clinical decision making regarding to extract or to retain lower impacted wisdom teeth. Specifically, for the study two individuals looked at 1,198 orthopantomographs or panoramic radiographs with 1,810 impacted lower wisdom teeth or third molars. Originally a total of 4,600 orthopantomographs were retrieved from those taken at The University of Jordan Hospital between the years 2010 and 2014, but 3,402 were excluded due to patient age being outside of the … Read more

The Predictive Value of using Panoramic X-Rays for Wisdom Teeth Surgery Complications

by

An interesting article titled “Predictive Value of Panoramic Radiography for Injury of Inferior Alveolar Nerve After Mandibular Third Molar Surgery,” appears in the 2017 edition of the Journal of Oral and Maxillofacial Surgery (vol. 75, pp. 663-679) written by Su et al. The article sought to explore if panoramic x-rays taken before wisdom teeth removal can predict possible injury of the inferior alveolar nerve. In the article the authors discuss how inferior alveolar nerve injury is the third most common complication following wisdom teeth removal. When inferior alveolar nerve injury occurs numbness of the lip or chin can occur along with difficulty speaking and chewing food. Current studies have shown inferior alveolar nerve injury occurs about 8% of the time after wisdom teeth removal with less than 1% expected to be permanent. Current practice has shown that panoramic x-rays can … Read more

Differences Among Classifying Wisdom Teeth using Panoramic X-rays and Cone-Beam Computed Tomography

by

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
