Outcome Measures

Primary Outcomes (1)

  • Change in root length in mm

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

    Root length will be measured at the initiation of orthodontic treatment and at an average of 24 months later.

Study Arms (1)

Experimental group

All patients who have initial and final records qualify in the experimental group.

Other: Intraoral Scan

Interventions

Intraoral ScanOTHER

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

Sampling MethodProbability Sample
Study Population

Patients who have undergone orthodontic treatment, and associated tooth movement, and have initial records directly before the initiation of treatment.

You may qualify if:

  • 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.

You may not qualify if:

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