Brit.

/priːˈdɛnteɪt/, U.S.

/priˈdɛnˌteɪt/

Origin: Formed within English, by derivation. Etymons: pre- prefix, dentate adj.

Etymology: < pre- prefix + dentate adj. With sense 2 compare scientific Latin Predentata, order name (O. C. Marsh 1894, in Amer. Jrnl. Sci. 148 90).

†1. Zoology. Having teeth only in the fore part of the upper jaw, as certain whales. Obsolete.

ΚΠ

1834 H. W. Dewhurst Nat. Hist. Cetacea 130 Predentate Cetacea; or, those with teeth only in the anterior part of the upper jaw.

2. Palaeontology. Of or relating to an order of dinosaurs characterized by possession of a predentary bone (in some classifications called Predentata, equivalent to the Ornithischia of others). rare.

ΚΠ

1894 O. C. Marsh in Amer. Jrnl. Sci. 148 89 A comparative series showing the relative development of the anterior and posterior branches of the pubis in six genera of American Predentate Dinosaurs is shown.

1923 Science 29 June 732/2 A complete skull of Protoceratops, a pre-dentate dinosaur, ancestral to the giant Ceratopsia.

1952 Condor 54 80 The symphysis is fused in predentate dinosaurs.

3. Medicine. Designating a child prior to the emergence of the first teeth; occurring before this developmental stage.

ΚΠ

1965 Arch. Oral Biol. 10 61 The accretion of filamentous and branching forms..did not appear to be solely dependent upon tooth eruption since these forms could be isolated from predentate infants.

1988 Clin. Immunol. Newsletter 9 190 No monomeric IgA and little IgG was observed in whole salivas from predentate infants.

2001 Jrnl. Dental Res. 80 2064/2 We found that breast-fed compared with bottle-fed children, and those given on-demand feeding, are likely to be at higher risk for predentate colonization of S[treptococcus] mutans.
