Objectives: Incontinentia pigmenti (IP) is an X-linked genodermatosis caused by a mutation of the IKBKG gene. The objective of this study was to present a systematic review of the dental and oral types of anomalies, to determine the total number and sex distribution of the anomalies, and to analyze possible therapies. Materials and methods: We analyzed the literature data from 1,286 IP cases from the period 1993-2010. Results: Dental and/or oral anomalies were diagnosed for 54.38% of the investigated IP patients. Most of the anomaly types were dental, and the most frequent of these were dental shape anomalies, hypodontia, and delayed dentition. The most frequent oral anomaly types were cleft palate and high arched palate. IKBKG exon 4-10 deletion was present in 86.36% of genetically confirmed IP patients. Conclusions: According to the frequency, dental and/or oral anomalies represent the most frequent and important IP minor criteria. The most frequent mutation was IKBKG exon 4-10 deletion. The majority of dental anomalies and some of the oral anomalies could be corrected. Clinical relevance: Because of the presence of cleft palate and high arched palate in IP patients, these two anomalies may be considered as diagnostic IP minor criteria as well.

One of interesting aspects in dermatology is the fact that skin may reflect the presence of anomalies in other organs and tissues. One such example is incontinentia pigmenti (IP), a rare, complex, X-linked genodermatosis. Clinical manifestations of IP according to evolution and prognosis can be considered as skin, as well as dental, eye, and central nervous system, changes. We have investigated a total of nine families with 25 subjects, 23 females and 2 males. In 12 female and 2 male subjects, all of them with clinical characteristics of IP, we observed the following abnormalities: teeth-shape anomalies (coni- or peg-like teeth), the presence of numerous cariotic teeth, early dental loss, delayed eruption, partial anodontia, and gothic palate. To our knowledge, this is the first time that the presence of gothic palate in patients with IP has been documented. As we found out, in two female subjects and one male subject, in which nonrandomed X inactivation did not occur, gothic palate could be supposed as characteristic of IP. [ABSTRACT FROM AUTHOR]
