Like Duolingo,
but for learning
dental X-rays.
Practice the calls dentists make every day: what's normal, what's not, and what to do next.
Try it right here — no sign-up. One radiograph, one call.
The full scan
Read panoramic X-rays without losing the landmarks.
Drag the light across the radiograph.
Built by a dentist
Every case checked by a licensed dentist.
Real radiographs
Train on real patient X-rays.
5-minute lessons
Made for study breaks.
Why it works
Dental X-ray practice that trains your eye.
Short, active reps for clinic, boards, and real patient care.
Stop calling every shadow a lesion
Cervical burnout, Mach bands, and normal anatomy all mimic decay while your eye is still training. Learn the look-alikes — so you know when it's caries and when it's nothing.
Read it like a dentist
Every case is a real radiograph with a licensed dentist's reasoning. Make your call first, then compare — and catch what you missed.
Your read
"Looks clear to me."
Expert read
Caries — distal of the molar.
Free while in early access.
Why we built Papilla
Diagnosis is
pattern recognition.
School teaches the facts. The patterns take practice — and the misses keep happening long after graduation.
I kept seeing the same pattern: healthy findings treated like disease, and subtle lesions missed until they became serious. Diagnosis is pattern recognition — I built Papilla to help students learn the patterns before real patients pay the price.
40%

In one study, dental students got only 53% of panoramic landmark questions right.
