PULP TISSUE REACTIONS TO SPECIFIC ORTHODONTIC MOVEMENTS: A LITERATURE REVIEW
A dental movement during an orthodontic treatment may generate an inflammatory or degenerative response on pulp tissue. As this tissue exposed to a mechanical load under different magnitude, frequency and length, it expresses both macroscopic and microscopic changes by induction of circulatory and vascular changes. However, most cases the pulp tissue has a tendency to recover itself keeping its structure and function. It has therefore been suggested that injury upon pulp produced by orthodontic forces is permanent, and the pulp tissue may eventually lose its vitality, although few researches refuse this correlation. This inconsistency in the literature is probably a result of invalid interpretations. To that extent the purpose of this literature review carried out at Universidad Cooperativa de Colombia in 2010 is to understand how the pulp disease may occur in response to therapeutically orthodontic tooth movements and whether these effects are temporary or permanent.
