Pulpal tissue response to orthodontic forces – a literature review

Journal Title: Forum Ortodontyczne - Year 2006, Vol 2, Issue 1

Abstract

AIM: The aim of the study was to review the results ofinvestigations of the effect of orthodontic force applicationon the pulpal tissue.MATERIAL: This literature review based on publishedpapers. In available Polish literature studies of the effect oforthodontic forces on the pulpal blood flow were not found.METHODS: The review includs papers studying theeffect of orthodontic force application on human pulpalblood flow. Results of histological, biochemical, radiographicstudies, thermal and electrical tests as well as laserDoppler flowmetry measurements of blood flow were presented.RESULTS: Investigators observed vacuolization of theodontoblast layer and alterations in microcirculatory systemof the pulp. They reported depression of pulpal respiration rate and increased response thresholds to electricalstimulation. Predentin formation activity was observed.Reduction in the pulpal blood flow during orthodonticforce application was also reported. CONCLUSIONS: Onthe basis of the presented literature review it may be concludedthat either brief or continuous orthodontic forcesinduce changes in the pulp tissue. The presented observationsare relevant for a more complete understanding ofthe biologic aspects of orthodontic treatment. Their clinicalimplications are not clear, thus further investigation isrequired. (Orthod. Forum 2005; 2:5-9)
