DentSloth 🦥: An AI-Powered Marketplace for Used Dental Instruments
Description and use
DentSloth automates the resale of used dental instruments from a single photo, providing identification, pricing, bilingual listings, and buyer matching.
Problem
New dental instruments are expensive and reselling used instruments is a chore, so many good instruments sit unused.
Outcome
DentSloth demonstrates a complete end‑to‑end pipeline that reduces the effort of reselling used dental instruments, potentially saving clinics money and reducing waste.
Workflow
- Take one photo of the instrument
- Gemma 3 4B vision model identifies instrument, brand, condition, defects, single‑use flag and confidence
- TabPFN predicts resale price, applies sanity rules and writes explanation
- Gemma writes bilingual listing (English + Hindi)
- Listing is saved to MongoDB with embeddings and published
- Sloth Run script matches new listings with buyers’ wishlists and sends a summary
Evidence
New dental instruments are expensive, and a young dentist opening a first clinic has to buy almost everything at once.
DentSloth removes the chore. A clinic takes one photo, and the sloth does the rest: Identify, Price, Write, Match, Starter Kit Builder.
On a hold‑out set of 120 rows, TabPFN reached a mean absolute error of Rs 58.3, compared with Rs 235.5 for a simple "average by instrument type" baseline.
The demo uses synthetic price data and fictional clinics. Prices are suggestions, not valuations.
