Orthodontic tooth movement regulated through mediators of inflammatory pathways-a review

The present scenario in the field of orthodontics has been focusing more on patient demands rather than achieving what is called as ideal for that particular patient. Esthetic and shorter treatment duration is nowadays the prime concern among the adults who seek for an orthodontic treatment. In such circumstances, carrying out tooth movement becomes a challenge for an orthodontist within the stipulated time. Various treatment modalities have been proposed in terms of biomechanics, alteration in cellular and molecular biology, surgery to accelerate orthodontic tooth movement in order to reduce the treatment duration. Hence it is necessary to understand the underlying biological implications of orthodontic treatment occurring during application of forces for various types of tooth movements. The present review was being undertaken to focus primarily on various biological aspects at cellular and molecular level and their interactions taking place during normal orthodontic loading of tooth or groups of teeth. The biological mechanisms controlling the shift from the stimulus, consisting of continuous force application, to the reaction, represented by the displacement of the tooth in the periodontal space, could be evaluated by monitoring the higher or lower rate of biomarkers in periodontium.
