Orthodontic Root Resorption

An undesirable and unexpected treatment result of orthodontics is loss of the tooth root. Close radiographic examination of orthodontically treated individuals show some loss of root length in nearly every patient . The incisors are the most susceptible while the molars seem to be the least affected. Generally root resorption may be described as mild, moderate and severe. The aim of this project is to investigate the presence of dentin matrix protein 1 (DMP1), dentin phosphophoryn (PP), osteopontin (OPN) and bone sialoprotein II (BSP II) in gingival crevicular fluid (GCF) of subjects undergoing an orthodontic treatment. The identification of a marker for root resorption could lead to a new test for monitoring root resorption during orthodontic treatment. By the means of a radiographic evaluation today we are not able to detect an ongoing root resorption especially in the early stages. The results obtained in this study needs a bigger sample group to validate its significance.
