Relative magnitudes of crown size reduction and body size reduction in 47-trisomy G.
Since crown size reduction has been observed in 47-trisomy G (M. M. COHEN and R. A. WINER, J Dent Res 44:197-208, 1965; M. M. COHEN, S. M. GARN, and M. A. GECIAUSKAS, J Dent Res 49:460, 1970) with delayed tooth formation timing (S. M. GARN, C. W. STIMSON, and A. B. LEWIS, J Dent Res 49:640, 1970), it is useful to compare the magnitude of crown size reduction with the magnitude of body size redu...
متن کاملIncreased crown-size asymmetry in trisomy G.
Trisomy G (Down's syndrome or "mongolism") is associated with multiple dental abnormalities (J. OSTER, Mongolism, Copenhagen: Danish Science Press, 1953). Teeth are frequently missing, all morphologic classes are involved, and the remaining teeth are characterized by size reduction (M. M. COHEN and A. WINER, I Dent Res 44:197-208, 1965; and M. M. COHEN, S. M. GARN, and M. A. GECIAUSKAS, J Dent ...
متن کاملEffect of agenesis on the crown-size profile pattern.
Agenesis and hypodontia are associated with crown-size reduction in the remaining teeth (S. M. GARN ET AL, J Dent Res 41:717, 1962, Nature 200:488-489, 1963; J Dent Res 42:13441363, 1963; H. J. KEENE, Amer J Orth 50: 445-451, 1964; and K. HANIHARA ET AL, J Anthrop Soc Nippon 73:72-81, 1965). The question arises as to whether crown-size reduction associated with tooth number reduction is uniform...
متن کاملGenetic basis of the crown-size profile pattern.
Although genetic control of crown diameters has been documented by a number of workers (R. H. OSBORNE ET AL, Amer J Hum Genet 10: 350-356, 1958; S. M. GARN ET AL, J Dent Res 44:228-242, 1965; D. W. LEWIS and R. M. GRAINGER, Arch Oral Biol 12:539-544, 1967; and D. H. GOOSE, J Dent Res 46:959-962, 1967), genetic involvement in crown-size patterning has not been ascertained for the whole dentition...
متن کاملAdrenal gland length in euploid and trisomy 18 fetuses at 11-13 weeks.
OBJECTIVES To establish a normal range for fetal adrenal gland length at 11-13 weeks' gestation and to investigate whether the length is altered in fetal trisomy 18. METHODS Fetal adrenal gland length was measured by three-dimensional ultrasound in fetuses at low risk of aneuploidies (n = 400) and another group at high risk, including 380 euploid fetuses and 41 with trisomy 18. The data of th...
