Operating the program

Anatomic location and color

• After starting the DS OML program, the Start page will appear on your screen.
• Here you can choose between six options for locating the oral mucosa lesion.
• After clicking on the relevant category, you will in the second step be shown different options for color rendering of the selected region based on sample images.
• For side-by-side comparison, transfer your image created with an intraoral camera into Decision Support by clicking either "Import picture" or "Twain import".
• The selected image is then automatically transferred to every page you access thereafter. You can change its size and position by clicking on it with your mouse.

Comparing different oral mucosa lesions

• If a differential diagnosis is indicated for an oral mucosal change, you can display both clinical pictures parallel to each other.
• To do this, click on the "i" in the upper left of the screen next to the corresponding differential diagnosis image.
• In the next step, you will have the option of looking at the text or the image corresponding to the differential diagnosis.
• Return to the previous page by clicking the "Back" button.

Importing image files

• The "Import picture" command (Ctrl + O) in the File menu allows you to import an image from any directory on your computer.
• After clicking on a picture in the selected directory, that image is previewed in the right-hand field of the window.
• The dimensions of the image are displayed, and the image can be enlarged or reduced using the magnifying glass icons.
• Once you have chosen an image, click the "Open" button to import it. Now you can enlarge or reduce the picture by clicking on it.
• The last directory opened remains available for additional image imports. You can delete the imported picture by clicking "Delete Image" in the Extras menu.

Index

• Clicking "Index" (Ctrl + I) displays a new window with diagnostic terms listed in alphabetical order.
• Highlighted terms in blue can be activated and show you immediately the sample images and the corresponding description of the relevant oral mucosa lesion (see 4.3.).
• If you run the mouse lightly over the terms, you will see a text field highlighted in yellow, which displays the description of the characteristic features and recommendations.
• The search function at the bottom of the window lets you find the desired clinical picture even more quickly and efficiently.
• After a letter is entered in the search field, the index is automatically positioned on terms starting with the selected letter.
