Charting the odontogram

The odontogram is the tooth chart at the heart of every appointment. It shows both arches as a row of teeth you can read at a glance and edit with a click. This guide explains how teeth, surfaces, and findings appear, how your spoken findings fill the chart in, and how to fix anything by hand.

How the chart is laid out

The chart shows two arches: the upper teeth on top, the lower teeth below. Each tooth is drawn as a small ring split into segments so you can see findings on individual surfaces at a glance:

• The four outer segments are the mesial, distal, buccal, and lingual surfaces.
• The center circle is the occlusal (or incisal) surface.
• The tooth number sits just below each tooth.

A Legend runs across the top of the chart. It shows what each color and symbol means: Caries, Composite, Amalgam, Inlay, and Onlay, plus markers for Crown, Bridge, RCT (root canal), and Note. If the legend is wider than the column, use the arrows on either side to scroll through it.

Note: A tooth marked Missing dims and shows an X. Whole-tooth findings like crowns, bridges, implants, root canals, and notes draw as overlays around the tooth, so the symbol stays readable even with several findings on one tooth.

How spoken findings fill the chart

When you dictate during an appointment, the assistant listens, interprets what you say, and places findings on the matching teeth automatically. Surfaces, conditions, mobility, and periodontal probing depths all flow in as you speak.

Two cues help you follow along:

• A small Cursor tag near the top right shows which tooth the assistant is working on, along with the aspect and direction it is reading. This is most useful during perio probing, when you call out numbers in sequence.
• Each tooth flashes briefly green the moment it updates, so you can confirm the finding landed on the right tooth.

Your changes save on their own a moment after each edit. A Saving… indicator appears while that happens — there is no Save button to press.

Editing or correcting a tooth by hand

You can adjust any tooth directly, whether the assistant placed the finding or you are charting manually.

1. Click the tooth on the chart. A small editor opens beside it, titled with the tooth number. Drag it by its header if it covers something you need to see.
2. Set whole-tooth flags. Tap any of the Flags pills — Crown, Bridge, Prosthesis, Implant, RCT, or Missing — to turn it on. Tap it again to turn it off.
3. Mark conditions by surface. In the Surfaces grid, find the row for the surface (M, D, B, L, or O) and check the condition: Caries, Composite, Amalgam, Onlay, or Inlay. Each surface holds one condition at a time, so choosing a new one replaces the old.
4. Set mobility. Under Mobility, choose None, M1, M2, or M3.
5. Add a note. Type any clinical observation in the Notes box. The note saves when you click away, and the tooth shows a dashed ring to flag that a note exists.
6. Close the editor with the × in its header. Your edits are already saved.

Tip: To remove something a dictation added by mistake, open that tooth and toggle the flag off or uncheck the surface condition — the same controls that add a finding also clear it.

Choosing FDI or Universal numbering

The tooth numbers on the chart follow your clinic's preferred notation. You can set it under Settings → Default Notation:

• FDI (International) — the two-digit numbering used across most of the world.
• Universal (US) — the 1–32 sequence common in the United States.

Switching the preference changes the numbers shown on the chart and used throughout the appointment; the findings themselves stay attached to the same teeth.

Note: Your spoken findings are matched correctly whichever notation you choose, so you can dictate in the numbering you are comfortable saying out loud.
