Treating dentigerous cyst by extracting wisdom teeth

by

An interesting article titled “Marsupialization of Dentigerous Cysts Followed by Enucleation and Extraction of Deeply Impacted Third Molars: A Report of Two Cases” appears in Cureus in April 02, 2022 written by Nedal Abu-Mostafa (vol. 14, no. 4, pp. e23772). The article discusses two cases of a dentigerous cyst (DC) that involves the crown or a portion of the crown of an unerupted or impacted tooth that more commonly affect mandibular or lower impacted wisdom teeth. In the article discussion is made of dentigerous cysts being the second most common odontogenic cysts. Dentigerous cysts are caused by an alteration of the reduced enamel epithelium and results in fluid accumulation between it and the enamel of the crown. The progression of dentigerous cystsis are slow and often do not present any symptoms and the patient learns about them through an x-ray or … 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
