Abstract

Background and Objectives: External root resorption is one of the dentist concerns with the fast retraction method of orthodontic treatment. Cone Beam Computed Tomography (CBCT) is commonly used in the detection and evaluation of teeth changes associated with various orthodontic treatments. This is a pilot study to investigate the severity and possibility of internal and external root resorption for orthodontic patients who undertook fast anterior teeth retraction using corticotomy.

Material and methods: Eleven patients’ radiographic records extracted from CBCT archive for patients who received fast retraction teeth movements by corticotomy. CBCT scans before and after treatment were interpreted the presence and amount of external and internal root resorption for all teeth. All of the statistical analyses were conducted using STATA Version 13.0 (StataCorp, College Station, Texas, USA).

Results: Only external root resorption was statistically significant and detected for those patients who received accelerating orthodontic treatment. The amount of root resorption ranged from 1 mm to 3 mm. In specific, some participants had 1 mm others 1-2 mm and the rest had 3 mm. anterior teeth were more affected than premolars.

Conclusion: CBCT scan should be considered to follow up cases with fast retraction orthodontic treatment because there is a high chance of external root resorption.
