About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Subject has initial records including CBCT scan and panoramic radiograph that are clear. Subject must have no restorations or significant loss in tooth structure in target teeth or teeth adjacent to target.

Exclusion criteria

  • Subjects who have records that are not clear, and who are missing target teeth.

Treatment and study plan

Intraoral Scan

Other

All patients will have an intraoral scan performed for measurements to be taken on.

Primary outcomes

  1. 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.
