NCT07690488

Brief Summary

This study compared handheld and mechanically assisted scanning to evaluate fascial edema after third molar extraction. The flexible ruler served as the reference. Linear measurements were taken from the tragus to the pogonion, from the tragus to the corner of the mouth, and from the lateral corner of the eye to the angle of the mandible.

Outcome Measures

Primary Outcomes (1)

  • Collect fascial anthropometric measurement

    The measurement of the distances between the tragus and pogonion, the tragus and labial commissure, and the angle of mandible and lateral canthus with the use of a flexible ruler, handheld scanning, and mechanically assisted scanning.

    At postoperative first week

Secondary Outcomes (3)

  • Collect of image acquisition time

    At postoperative first week

  • Collect of the number of repeated scans

    At postoperative first week

  • Collect of patient reported outcomes

    At postoperative 7th day

Study Arms (1)

20 patients extracted impacted mandibular third molars

20 patients extracted unilaterally ot bilaterally mandibular third molars. Impaction classified as Pell and Gregory Level B and Winter Class II (vertical position)

Procedure: Measurement with flexible rulerProcedure: Measurement with handheld scanningProcedure: Measurement with mechanically assisted scanning

Interventions

Measurement with handheld scanningPROCEDURE

Face image of patients were collected using a LiDAR-equipped mobile device and the three dimensional scanning application. A researcher was manually moved around the participant's head along a horizontal trajectory until complete facial coverage and adequate mesh reconstruction.

Measurement with mechanically assisted scanningPROCEDURE

Face image of patients were collected using a LiDAR-equipped mobile device and the three dimensional scanning application. For recording, the device is positioned on a mechanism.

Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

20 healthy patients enrolled with bilateral or unilateral impacted mandibular third molars. Impaction classification was Pell and Gregory Level B and Winter Class II (vertical position).

You may qualify if:

  • Presence of at least one impacted mandibular third molar,
  • Complete root development of the impacted tooth,
  • Impaction classified as Pell and Gregory Level B and Winter Class II (vertical position)

You may not qualify if:

  • Pregnancy or lactation;
  • Neurological, endocrine, or psychiatric disorders associated with tremor or hereditary disorders affecting motor function,
  • Facial asymmetry, facial deformity, or facial hair that could interfere with facial contour assessment;
  • Current or planned use of medications that may influence postoperative facial edema, such as corticosteroids;
  • Presence of chronic conditions that could mimic facial edema or a history of complications such as hematoma or subcutaneous emphysema.
