Moreover, the RANKL/Osteoprotegerin system has been shown to be related to odontoclast activity.
When tooth resorption occurs, cells called odontoclasts break down the dentin layer of the tooth.
Both layers form the barrier that prevents resorption and odontoclasts (similar to osteoclasts) from adhering or reabsorbing unmineralized matrix.
Root resorption results from the activity of odontoclasts, which play a role similar to that of osteoclasts in bone resorption.
Morphological and functional properties of odontoclasts on dentine resorption.
The apparent mechanism involved consists of significant reductions in the numbers of odontoclasts, and mononuclear cells on the dental roots, as well as in the alveolar bone, ultimately slowing down the bone remodeling process thereby the pace of tooth movement.19
This is attributed to procedural considerations and the higher cellular content of primary pulp, where undifferentiated mesenchymal cells may differentiate into odontoclasts in response to caries or the pulp medicament, leading to IR [Kennedy and Kapala, 1985; Kopel, 1992].
