Growth of the hard palate in infants with Down syndrome compared with healthy infants—A retrospective case control study

A reference is omitted from the second sentence of the third paragraph in the Introduction section.

The sentence should read: The hard palate of DS adolescents is often described as high arched and constricted or narrow [4, 11, 12], but data in the literature are contradictory [13, 14], depending on patient age [23] of the studied DS group.
