Epstein pearls are the small white nodules found on the roof of a newborn's mouth.
Step-by-step explanation:
The small white nodules on the roof of a newborn's mouth are characteristic of Epstein pearls.
Epstein pearls are a common finding in newborns and are small, white, cystic lesions that appear on the gums and roof of the mouth. They are harmless and typically resolve on their own within a few weeks or months.

Down syndrome is a genetic disorder characterized by intellectual disability and certain physical features. And a cleft palate is a congenital condition where the roof of the mouth does not fully close during fetal development.
