External cervical resorption detected via cone‐beam computed tomography in a patient with myelin oligodendrocyte glycoprotein antibody–associated disease: A case report

External cervical resorption may occur in patients with MOG antibody-associated disease, which is clearly detected on cone-beam computed tomography. Therefore, dental screening is essential for these patients before initiating bisphosphonate therapy. Larger sample sizes are crucial to determine any possible association between external cervical resorption and MOG antibody-associated disease.
