Rett syndrome--a rare and often misdiagnosed syndrome: case report.

Rett syndrome is a recently discovered, progressive neurological disorder that occurs exclusively in females early in life. Females with this rare and often misdiagnosed clinical entity have unusual but distinctive oral/digital habits. Dentists aware of Rett syndrome and its distinct manifestations will be able to aid in early diagnosis and treatment of those afflicted. A case report of a 4-year, 3-month-old white female with Rett syndrome and review of pertinent literature are presented. The previously reported oral/digital habits and oral manifestations of Rett syndrome are listed along with other unreported oral findings. Many of these oral manifestations are not unique to Rett syndrome. There is a likelihood that they may be related to trauma secondary to the excessive oral/digital habits, poor gait, and seizure activity.
