Bednar's aphthae can still be found in newborn infants but have nearly disappeared from recent paediatric literature.
To find out the incidence of Bednar's aphthae among newborn infants during the first week of life and the factors associated with the ulcers.
Clinical findings and statistical data were documented of 1,654 infants routinely examined for preventive reasons in two obstetric hospitals in Cologne, Germany.
Bednar's aphthae were found in 236 of the 1,494 neonates examined (15.8%) in whom the whole palate could be visualized. They were associated with spontaneous birth at term, nutrition with formula, and mucosal hyperaemia of the typical anatomical location.
Bednar's aphthae are not a rare phenomenon and still commonly occur in neonates.
