the Effect of Different Background Color and Skin Tone on the Accuracy of Auricular Scanning

Condition(s) studied

Investigational drug(s) / intervention(s)

Black background: Changing the background color during scanning to evaluate its effect on scan quality .

White background: Changing the background color during scanning to evaluate its effect on scan quality .

Participant own skin as a background: Changing the background color during scanning to evaluate its effect on scan quality .

Study summary

The goal of this study is to find the best miss and match background color around an ear when taking scans for it , the investigators will recruit participants of three different skin tone and will scan their ear three times; one scan without any background, second scan with black one and the third scan with white background, then the investigators will take an actual physical impression of the participants ear and the investigators will obtain a cast which will be scanned also and its scan will be compared to the three scans taken with different backgrounds to find the best combination.

Eligibility

Primary outcome measure(s)

• Evaluation of the effect of different backgrounds and skin tones on trueness of auricular scans via intraoral scanner. — The study is expected to take place over a 6-week period. Each participant will be scheduled for one session lasting approximately one hour.
  The resultant standard tessellation files (STL) of every scan done via the intraoral scanner will be compared to the STL of the scan done via the extraoral scanner of the same participant by a metrological software to evaluate trueness.
