Orthodontic and orthopedic treatment of a patient with incontinentia pigmenti

Abstract

Incontinentia pigmenti is an uncommon, inherited disorder with predominantly ectodermal manifestations that is associated with skin (100%), dental (90%), skeletal (40%), central nervous (40%), and ocular (35%) deformities. It is an X-linked dominant disease, usually lethal in males and occurring in female infants. The dental effects include delayed eruption, partial anodontia, microdontia, and cone or peg-shaped teeth. The dental, clinical, and radiological findings in a 16-year-old female are presented here. The patient had peg-shaped teeth and a unilateral maxillary transverse discrepancy associated with oligodontia in the maxillary and mandibular arches. Orthodontic treatment included rapid maxillary expansion and fixed orthodontic therapy for prosthetic purposes and elimination of the functional midline shift.
