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.
Detailed description
This study compared Lidar-based scanning methods for evaluating fascial edema after third molar extraction. The three methods assessed were flexible ruler measurement, handheld scanning, and mechanically assisted scanning. Lidar-based scanning was performed using a mobile device and a dedicated application. Linear measurements were obtained from the tragus to the pogonion, from the tragus to the corner of the mouth, and from the lateral canthus to the angle of the mandible. The study objectives were to compare scanning methods, evaluate acquisition time and the number of repeated scans required for mobile scanning, and assess patient-related outcomes using a questionnaire.
Interventions
PROCEDUREMeasurement with flexible ruler
linear measurements were obtained directly using a flexible ruler marked in millimeters
PROCEDUREMeasurement with handheld scanning
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.
PROCEDUREMeasurement with mechanically assisted scanning
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.
