Questions and answers about the charting drill

A listening drill for dental charting. Your browser speaks a callout the way an operator dictates it, such as "number 3, MOD amalgam", you chart it on the odontogram, and ChartCall grades the tooth, the surfaces and the material or condition separately and names whichever you missed.

Dental assisting and dental hygiene students learning to chart from dictation, veterinary technology students learning to chart a COHAT, people training on the job, and instructors who want to play callouts to a lab from a projector.

Yes. Switch the chart to canine or feline at the top of the drill, practice, exam or projection page. The dog chart has 42 permanent teeth and the cat chart 30, both in modified Triadan numbering, with deciduous charts for puppies and kittens. There are 36 invented dogs and cats with 229 findings, called the way a veterinarian dictates during a COHAT.

As the quadrant digit and then the position: 104 is one oh four, 309 is three oh nine, 110 is one ten and 411 is four eleven. Sometimes the tooth is named instead, such as left mandibular first molar for 309. Grades are said as words, so mobility 2 is heard as mobility two.

Everything on the dog and cat charts is free, with no account: the daily drills of 10 callouts, every practice category, the exam and projection mode. Each chart keeps its own progress in this browser.

Yes. Everything on the site is free, with no account: the daily drills, every practice category on the human, dog and cat charts, the timed exam of 40 callouts, projection mode, the session history, the glossary and the guide. There is no paid plan.

No. All 60 human cases with 363 findings, and all 36 dog and cat cases, are invented for practice. No real patient data is used anywhere, and nothing you chart here is a clinical record.

Callouts are spoken by your browser's own speech engine. Check the volume and the voice picker. If your browser has no speech voices, the callouts are shown as text instead and the page says so. Chrome, Edge, Safari and Firefox on a computer can all speak them.

Universal by default: 1 to 32 for permanent teeth and A to T for primary teeth. A toggle switches the chart and the spoken callouts to FDI two digit numbering. The dog and cat charts always use modified Triadan numbering.

Each part is graded on its own. The feedback names the part that was off: the tooth, a surface left off or added, or a material or condition that differed from the callout. Composite for amalgam is a material miss even if the tooth and surfaces are right.

In this browser's local storage only. Nothing is uploaded. The progress page exports it as a JSON file, which you can import on another browser.

It teaches one consistent set of conventions, the common US ones, and the guide says where practice varies. Where your program differs, for example in chart colours or abbreviations, follow your program.
