The purpose of this study was to evaluate the amount of external apical root resorption (EARR) secondary to orthodontic treatment in patients with Short Root Anomaly (SRA) using Cone Beam Computed Tomography (CBCT) at the University of the Pacific Orthodontic Clinic. Root resorption changes ranged from 0.92-1.3 mm for all incisors. Between the Non-Hispanic and Hispanic group, there was no statistical significance for all tooth length changes. There is a statistically significant difference in the root resorption of SRA teeth and non-SRA teeth (0.55mm).
Learning Objectives:
After this lecture, attendees will be able to:
Compare visual scoring versus CBCT quantitative method of tooth length.
Compare the magnitude of root resorption between Hispanic and Non-Hispanic SRA affected individuals.
Determine if there is a difference in the magnitude of root resorption between SRA teeth and non-SRA teeth.
