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 ...

The, fact that root-length measurements may be made on 450 oblique-jaw radiographs of older adolescents with reasonable replicability even on a year-to-year basis (GARN, VAN ALSTINE & COLE, J Dent Res 57:A114, 1978) opens the possibility of exploring root-length crown-size correspondences in the mandibular dentition. Taking, then, root-length measurements for C through M2 on 122 subjects aged 1...

BACKGROUND Tooth crown dimensions vary between different ethnic groups, providing insights into the factors controlling human dental development. This present study compares permanent mesiodistal (MD) and buccolingual crown dimensions between four ethnic groups, highlighting patterns of tooth size between these groups and considers the findings in relation to genetic and environmental influence...

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...

In postnatal dental development, and in crown size itself, there is a demonstrable "distance gradient" so that teeth closer together within a jaw quadrant show higher correlations. Thus, adjacent teeth exhibit systematically higher commonality in both tooth formation and crown size than more remote teeth in the same quadrant, despite absolute differences in formation (calcification, root elonga...

As shown in 870 white participants in the National Collaborative Perinatal Project (NCPP), maternal health status during pregnancy and birth size are systematically related to mesiodistal and buccolingual crown dimensions of I1, I2, dc, dm1, dm2 and M1. Maternal diabetes, maternal hypothyroidism and large size at birth are associated with larger maxillary and mandibular teeth in white children....

Although the existence of a relationship between crown size and body size has previously been questioned 'S. M. GARN, and A. B. LEWIS, Amer Anthrop 60:894-880, 1958; H. A. BAILIT and J. S. FRIEDLAENDER, Amer Anthrop 68:665672, 1966), recent studies show that there are systematic, positive, but low-order, correlations between crown size and various body dimensions (R. FILIPSSON and L. GOLDSON, A...
