Orthodontic movement in deciduous teeth

Dental Press Journal of Orthodontics, 2015
Deciduous teeth exfoliate as a result of apoptosis induced by cementoblasts, a process that reveals the mineralized portion of the root while attracting clasts. Root resorption in deciduous teeth is slow due to lack of mediators necessary to speed it up;
