Altering osteoclast numbers using CTSK models in utero affects mice offspring craniofacial morphology.

The findings of this study suggest that modulation of osteoclast numbers during pre- and post-natal development may be a previously unknown factor in the aetiology of skeletal malocclusions. An improved understanding of the factors affecting bone homeostasis during development and growth may help in the development of future therapies that would target the early intervention of skeletal malocclusion.
