Study & Design

• Study Type: Interventional
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Amount of orthodontic root resorption. The premolar roots will be scanned with a MicroCT scanner and the extent of root resorption measured.[4 weeks post orthodontic forces]

Secondary Outcome Measures

Name	Time	Method
Orthodontic tooth movement. This will be measured clinically inside the mouth every 2 weeks for 8 weeks, and also from models from impressions of the teeth.[32 weeks after commencement of orthodontic treatment]
