RESUMO
Incontinentia pigmenti (IP) is a genodermatosis with an X-linked dominant mode of inheritance, characterized by ectodermal, mesodermal, neurological, ocular, and dental manifestations. The purpose of this case study was to report the oral and dental manifestations of an IP case in a Venezuelan pediatric patient. A 9 year-old Venezuelan girl was evaluated. She showed macular pigmented lesions in her face, trunk, back, legs, and fingers as well as abnormal hair distribution, alopecia on the vertex, and hypoplasia of eyebrows. During the dental examination, conical shaped-teeth and delayed dental eruption was evidenced. The microanalytical examination showed dentin without significant alterations in the mineralization except for hypermineralization in focal areas. In addition, a decrease in the enamel mineralization was observed.
