[Biochemical aspects of orthodontic movement: recent findings and trends].

The orthodontic tooth movement produces physical and biochemical reactions in the periodontium. Tooth movements can be expressed by cell activation inducing bone resorption and remodelling. Substances as cAMP, cGMP, neuropeptides, prostaglandins and ormons play a basic role in this mechanism as mediators and modulators of the cellular responses. The Authors review the possibility to control the degree of the tooth movement acting on this biochemical process.
