Official Title: An Evaluation of Root Length Measurements Using Intraoral Scan and Panoramic

Brief Summary: This study will attempt to validate a method of estimating root length on panoramic radiograph by crown measurement on intraoral digital scans.

Detailed Summary: Intraoral digital scans will be taken on patients who have completed orthodontic treatment, and measurements will be made on the crown dimensions. These dimensions will then be applied onto the same teeth as seen on panoramic radiographs and a mathematical relationship will be determined for root length. Changes in root length will be measured from initial records to treatment complete panoramic radiographs and these estimates will be compared to actual root length changes as measured in CBCT (Cone Beam Computed Tomography) records.
Sponsor: Loma Linda University

Current Primary Outcome: Change in root length in mm [ Time Frame: Root length will be measured at the initiation of orthodontic treatment and at an average of 24 months later. ]

Changes in root length will be calculated, starting from the initiation of orthodontic treatment to completion of treatment, at an average of 24 months.


Original Primary Outcome: Same as current
