How to take a good photo
Image quality directly affects analysis accuracy. Follow these steps for the best result.
1
Good lighting is essential
Use natural light or a bright lamp. Avoid dark rooms. The oral cavity must be clearly visible.
2
Open wide and hold still
Use a mirror to position yourself. Keep the camera 15–20 cm from the lesion. Avoid blurry shots.
3
Focus on the lesion
Tap the lesion on screen to focus. The area of concern should fill at least 40% of the frame.

AI prediction
The detected lesion is very likely a minor aphthous ulcer — a common, harmless mouth ulcer of the inner lip. Its round yellow-grey base, red halo, small size and single site are all reassuring features, with no signs of concern. Almost all of these heal on their own within 7–14 days.
