Research of vitamin D3 influence on the growth and compact bone density measured by morphometric indices

This paper investigated the dependence of density and cortical bone growth on different doses of vitamin D over a long time period. The development of a bone was followedby Exton-Smith, Garn and Barnett-Nordin morphometric indices. The results clearly shown that vitamin D has a positive effect on bone density as well as its volume, which is expressed through the morphometric indices, and that deficiency of vitamin D reduces bone density and its volume. In this study we reach the conclusion that the Exton-Smith morphometric index provides more complete information on the volume in function of bone growth and vitamin D in relation to other indices, primarily because it also includes as a parameter length of the bone.
