X-linked hypophosphatemic rickets: Orthodontic considerations and management. A case report.

ABSTRACT

X-linked hypophosphatemic rickets (XLH) is a rare condition affecting bone metabolism. It has characteristic dental features such as poorly mineralised dentine, spontaneous abscess formation in the absence of caries and taurodontism. There are limited published data about patients with this condition undergoing orthodontic treatment, and there is no clear guideline on the suitability of orthodontic treatment in this cohort. We present a case report of a patient with XLH with a confirmed PHEX gene mutation undergoing orthodontic treatment and clinical recommendations to support treatment.
