Odontogram and FDI dental chart software: what Dr Dental IQ records

What an odontogram is

An odontogram, also called a dental chart or tooth chart, is a diagram of the mouth that shows every tooth and what has been found or done to it. It is usually the first page a dentist opens, because it answers three questions at a glance: which teeth are healthy, which have been treated, and which still need work.

A paper chart shows this at one visit. A digital chart keeps every visit, so the dentist can see how a tooth changed over time.

How FDI numbering works

FDI (ISO 3950) gives every tooth a two-digit number. The first digit is the quadrant — 1 upper right, 2 upper left, 3 lower left, 4 lower right. The second digit is the position counted from the midline, from 1 for the central incisor to 8 for the third molar. So 16 is the upper-right first molar and 36 is the lower-left first molar.

Dr Dental IQ shows all 32 permanent teeth in this numbering (11–48). The wisdom teeth (18, 28, 38, 48) can be shown or hidden. The same numbers are used in treatments and in the findings of the AI radiograph assistant, so a note about tooth 46 always means the same tooth.

What Dr Dental IQ records for each tooth

• Condition: healthy, caries (with a severity from mild to severe), composite filling, amalgam filling, root canal, zirconia crown, veneer, implant, extracted or missing.
• Surfaces: mesial, distal, occlusal, buccal, lingual and incisal, so a filling or a lesion is recorded on the surface where it is.
• Status of the work: existing, planned, in progress or completed.
• Photos and notes attached to the tooth, kept with its history.

The history of every tooth

Each tooth has its own record with four tabs: status, timeline, photos and notes. The timeline lists treatments, changes of condition, photos and notes in order, with the price recorded for a treatment, so a dentist can see what was done to tooth 26 and when.

How the chart fits the treatment workflow

When a treatment is recorded for a tooth, the chart shows it: planned work as planned, work under way as in progress, finished work as completed. Recording a treatment does not erase what the dentist charted for that tooth: a tooth marked with caries stays marked until the dentist updates it.

The chart also feeds the treatment plan. When the clinic uses the AI radiograph assistant, only findings the dentist has accepted can be added to the chart, as planned work.

What it does not claim

• It does not diagnose. The chart records what the dentist enters or accepts; it decides nothing on its own.
• It covers the 32 permanent teeth (FDI 11–48). Primary-tooth numbering and a periodontal chart are not part of it today.
• It is the clinic's own record, kept inside that clinic's account; other clinics cannot see it.
