Dental findings and management in a child with hypomelanosis of Ito

Hypomelanosis of Ito (HI) is a rare neuroectodermal disorder characterized by hypopigmented whorls of skin along the Blaschko lines. Mental retardation and intractable epilepsy are also commonly observed in HI. However, there are only a few published reports describing dental observations in HI patients. Here, we report the oral management and novel dental findings of a male HI patient aged 3 years and 10 months. The chief complaint was spontaneous gingival bleeding due to gingival hyperplasia induced by anticonvulsants, which was improved with plaque control and gingival massage. Numerous additional dental abnormalities were also evident, including enamel hypoplasia and large pulpal chambers.
