The odontogram draws on every tooth what was noted and what was done on it. Each drawing below is the one in the app’s legend, beside what the finding means and how you recognise it on the odontogram.

  1. Tap the “i” button, What the colours and drawings mean, at the bottom of the odontogram’s left bar.

Legend opens over the odontogram; close it by tapping ×.

Tap the “i” button, What the colours and drawings mean, at the bottom of the odontogram’s left bar.

Caries, fillings, recurrent caries and caries at the gum line are noted on the affected surface, in the tooth’s panel: tapping the same surface again goes from caries to a filling, then to recurrent caries. A sealant is noted on the whole tooth, under More.

Drawing Finding What it means How you recognise it
Caries on the occlusal surface Caries Untreated caries, on the surfaces you marked. Red on the affected surface, and the tooth number shows on red.
A filling on the occlusal surface Existing Filling A filling the tooth already has. Green on the surface.
Recurrent caries on the occlusal surface Recurrent Caries Caries that has come back next to a filling. Green ringed in red; orange in the 3D view.
Caries at the gum line Caries at the gum line Caries at the edge of the gum. Red fading away from the gum.
A sealant on the occlusal surface Sealant A sealant protecting the grooves of the biting surface. Violet on the biting surface.

Noted in the tooth’s panel: Not Present, Crown, Root Canal, Retained Root and Fracture are in view, while Implant, Bridge Pontic, Post and Veneer are under More. Splinted teeth show once the doctor has performed the splinting.

Drawing Finding What it means How you recognise it
A crown Crown A prosthetic crown on the tooth. Blue-grey over the crown of the tooth.
A veneer Veneer A veneer bonded to the front face. Cream over the front face.
An implant Implant An implant in place of the root, with its crown. A screw in place of the root, under the crown.
A bridge over three teeth Bridge A bridge pontic: a tooth with no root, held by the teeth next to it. The pontic has no root; a line joins it to the teeth holding it.
A missing tooth Not Present The tooth is missing. Only a dashed outline.
A retained root Retained Root Only the root is left of the tooth: above the gum, below it or a small fragment. The tooth is drawn up to where the root is left, the rest outlined.
A crown fracture Fracture The tooth is fractured, on the crown or the root, vertically or horizontally. A zigzag line across the crown or the root.
Three root canals Root Canal The tooth’s canals are treated: completely, partially or only the pulp chamber (pulpotomy). Red in the canals: down to the tip when complete, dotted after the filling when partial, only in the pulp chamber for a pulpotomy.
A post Post A post in the canal, holding the tooth’s build-up. Grey in the canal.
Four splinted teeth Splinted teeth Teeth tied together so they do not move. A line joins the splinted teeth.

Noted on the whole arch, from Upper Arch or Lower Arch, above the odontogram.

Drawing Finding What it means How you recognise it
A total denture Total Denture A denture replacing every tooth of the arch. A pink base under the arch; the denture’s teeth pale pink.
A partial denture Partial Denture A denture replacing only some of the teeth. The base under the denture’s teeth only.
A fixed appliance Fixed appliance A fixed orthodontic appliance, metal or ceramic. Brackets and the wire between them; ceramic brackets are lighter.
Aligners Aligners Clear aligners that straighten the teeth. Clear blue over the crowns.
A removable appliance Removable appliance An orthodontic appliance the patient takes out. The plate, under the biting surfaces.
A fixed retainer Fixed Retainer A wire bonded behind the front teeth, holding them in place after orthodontic treatment. A wire behind the front teeth.

Noted under Probing, in the tooth’s panel. Every value also shows as a number, not by colour alone.

Drawing On the odontogram What it means How you recognise it
A tooth’s probing Probing The gum’s edge and the probing depth, at six points on every tooth. Red: the edge of the gum. Blue: the bottom of the pocket; the band above it is the pocket.
Bleeding on probing Bleeding on probing Where the gum bled when probed. A red dot on the gum’s edge, at the site that bled.
A grade 2 furcation Furcation Bone has receded where the roots part, graded 1 to 3. A circle where the roots part: empty for grade 1, half filled for grade 2, filled for grade 3.
Grade 2 mobility Mobility How much the tooth moves, graded 1 to 3. Above the tooth: arrows either side of the grade.
A deep pocket, five millimetres A deep pocket A probing depth of 4 mm or more. The value, on orange, under the tooth number while probing.
A healthy depth, two millimetres A healthy depth A probing depth under 4 mm. The value, on green.
Drawing On the odontogram What it means How you recognise it
Number 36 on red Caries to treat The tooth has untreated caries. The tooth number, on red.
A 3 beside the number In the history How many times the tooth was worked on. A number beside the tooth number, filled for the visit chosen in History.
A tooth outlined in blue Already noted with the brush When you note one finding on several teeth, the teeth you have already noted it on. Outlined in blue; a blue ring in the 3D view.
A faded tooth Faded The tooth has nothing to do with what is open, for example the plan shown. Drawn faded.
Drawing On the odontogram What it means How you recognise it
A tooth with a dashed orange outline Treatments planned The tooth has treatments in the plan shown. A dashed orange outline; a hatched orange ring in the 3D view.
A tooth outlined in blue, picked in the plan Tooth picked in the plan The tooth you are adding procedures to in the plan. Outlined in blue.
The Stage 2 label Planned The stage the tooth’s next treatment belongs to. The stage’s label, for example “Stage 2”.
A tick on green Performed Everything planned on the tooth is done. A tick on green.
The today label Today The tooth has treatments on today’s visit. The “today” label.
A coloured dot Doctor The doctor of the tooth’s last treatment. A dot in the doctor’s colour, under the tooth number.

A crown, an implant, a bridge pontic, a missing tooth or a retained root describe the tooth as it is now. Caries and fractures noted on that tooth before are no longer drawn, but they stay in the tooth’s history. A root canal is drawn together with any of them, for example under a crown.
