An Evaluation of Root Length Measurements Using Intraoral Scan and Panoramic Radiographs

An Evaluation of Root Length Measurements Using Intraoral Scan and Panoramic

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

Study Overview

• Status: Completed
• Conditions: Root Resorption
• Intervention / Treatment: Other: Intraoral Scan

Detailed Description

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.

• Study Type: Observational
• Enrollment (Actual): 21

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 13 years to 55 years (Child, Adult)

Study Population

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

Description

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.
