Abstract

Tooth eruption depends on the presence of osteoclasts to create an eruption pathway through the alveolar bone. In diseases where osteoclast formation, or function is reduced, such as the various types of osteopetrosis, tooth eruption is affected. Diseases in which osteoclast formation or activity is increased, such as familiar expansile osteolysis and Paget's disease, are associated with dental abnormalities such as root resorption and premature tooth loss. Less is known about the origin of the dental problems in these conditions as there are no rodent models of these diseases as yet. In this short review, the genes currently known to be mutated in human osteoclast diseases will be reviewed and, where known, the effect of osteoclast dysfunction on dental development described. It will focus on human conditions and only mention rodent disease where no clear data in the human are available.
