The term comes from the Greek "odonto" (tooth) and "gram" (drawing or record). Unlike a simple written note, an odontogram gives an instant visual overview: the clinician, patient, and any treating colleague can see at a glance which teeth carry fillings, crowns, decay, or implants, and which are missing.
Dental charting is performed at every examination or recall appointment. The dentist or auxiliary calls out findings tooth by tooth — reading from upper right to upper left, then lower left to lower right — while a second person records them on the chart. Modern dental software makes this a one-person task: the clinician taps or clicks each tooth directly on a digital odontogram displayed on a screen or tablet.
Two numbering systems dominate clinical practice. FDI notation (ISO 3950) is used in Europe, South America, Asia, and most of the world. Each tooth gets a two-digit code: the first digit (1–4 for permanent, 5–8 for primary) identifies the quadrant, and the second (1–8) identifies the tooth within that quadrant. So the upper right first molar is 16, and the lower left canine is 33.
A numeração Universal (usada nos EUA) atribui a cada dente permanente um número único de 1 a 32, começando no terceiro molar superior direito (#1) e seguindo no sentido dos ponteiros do relógio até o terceiro molar inferior direito (#32). Os dentes da dentição primária são designados com as letras A-T. A notação Palmer, usada no Reino Unido, Irlanda e Austrália, escreve a posição 1-8 (A-E para os dentes da dentição primária) dentro de um colchete que marca o quadrante. Enquanto Universal é simples de memorizar para uma visualização de um único arco, FDI é mais intuitivo para referência cruzada de quadrantes e é preferido em publicações internacionais. Este odontograma online suporta todos os três - alterne livremente e o Findings Summary será atualizado automaticamente.
A complete dental chart records more than just decay. Restorations (fillings), crowns, fixed bridges, root canal treatments, sealants, implants, and missing or extracted teeth all appear as symbols or colour codes. Periodontal findings — probing depths, recession, bleeding on probing, furcation involvement — are often charted on a separate periodontal grid. Digital systems like DodoDentist layer both on the same tooth diagram for a complete clinical picture.
Accurate dental charting requires good lighting, a probe or explorer, and a systematic approach. Work quadrant by quadrant and surface by surface — mesial, occlusal/incisal, distal, buccal, and lingual — for every tooth. Call out the tooth number using the system your practice has adopted, then the surface and condition (e.g. "16, MOD composite"). Note existing restorations and new caries separately, so treatment records stay clear over time.
Os odontogramas em papel ainda são comuns em consultórios menores e clínicas universitárias, mas o registro digital tem vantagens claras. Os registros digitais são legíveis, pesquisáveis e compartilháveis; podem ser vinculados a radiografias e planos de tratamento; e eliminam erros de transcrição. Software baseado em nuvem como DodoDentist adiciona lembretes de appointments, integração de faturamento e acesso em múltiplos dispositivos — para que seus registros estejam disponíveis no seu tablet ao lado da cadeira, no seu desktop na recepção e no seu telefone entre clinics. A ferramenta interativa nesta página dá a você uma noção de como o registro digital funciona antes de você se comprometer com um sistema completo.
The table below lists the most common dental charting abbreviations and their plain-language meanings. Conventions may vary slightly between practices and countries.
| Abbreviation | Meaning |
|---|---|
| MO | Mesio-Occlusal — two-surface filling on the mesial and occlusal faces |
| DO | Disto-Occlusal — filling on the distal and occlusal faces |
| MOD | Mesio-Occlusal-Distal — three-surface filling spanning the full occlusal table |
| RCT | Root Canal Treatment — pulp removed, canals shaped and filled |
| Ext | Extraction — tooth removed or planned for removal |
| Imp | Implant — titanium fixture placed in the jawbone |
| Cr | Crown — full-coverage restoration capping the entire tooth |
| Br | Bridge — fixed prosthesis replacing one or more missing teeth using adjacent teeth as abutments |
| Se | Sealant — thin protective coating applied to pits and fissures |
| Ca | Caries — active tooth decay; may be coded by surface (e.g. Ca-MO) |
| F | Filling / Restoration — amalgam, composite, or other restorative material |
| Perio | Periodontal disease — bone or attachment loss noted |
| BOP | Bleeding On Probing — clinical sign of gingival inflammation |
| Fu | Furcation involvement — disease affecting the root fork of multi-rooted teeth |
An odontogram (also called a dental chart or periodontal chart) is a graphical record of the condition of a patient's teeth. Each tooth is drawn schematically and annotated with clinical findings — caries, restorations, crowns, missing teeth, implants, and more — giving the dental team an instant visual overview of oral health status.
The FDI (World Dental Federation) two-digit system is used internationally. The first digit identifies the quadrant (1=upper right, 2=upper left, 3=lower left, 4=lower right) and the second identifies the tooth within that quadrant (1=central incisor, 8=third molar). Universal numbering, standard in the USA, numbers all 32 permanent teeth 1–32 clockwise from the upper right. For example, the upper right first molar is #3 in Universal and #16 in FDI. This tool also supports Palmer notation, used in the UK, Ireland and Australia, which writes the position 1–8 inside a quadrant bracket.
Paper charts require manual drawing and are prone to legibility errors; digital charting (like DodoDentist's built-in module) is faster, searchable, and integrates with appointment scheduling, billing, and treatment planning. Paper records must be physically stored; digital records are encrypted and backed up automatically.
Periodontal charting extends the basic odontogram by recording probing depths (in millimetres) at 6 sites per tooth, furcation involvement, recession, mobility scores, and bleeding on probing. It is used to diagnose and monitor gum disease. This page covers condition charting on a basic odontogram — for full periodontal charting, use the dedicated tool: Periodontal Chart tool
Select an active condition from the colour-coded palette (e.g. Caries). Then click any tooth on the chart — or one of the crown surface circles between the arches — to apply that condition. The chart is the same anatomical odontogram DodoDentist uses in the clinic, so a crown condition tints the crown, a root canal draws a canal line down the root, an implant draws its threads, and a missing tooth becomes a dashed outline. The Findings Summary updates in real time. To clear a tooth, select "Healthy" then click the tooth. Press Reset to start a fresh chart.
Yes. Use your browser's Print function (Ctrl+P on Windows, Cmd+P on Mac). The tool includes print-optimised styles so the chart renders clearly in black and white or colour.
This online odontogram is designed for educational use, demonstrations, and quick reference. For full clinical charting integrated with patient records, treatment plans, billing, and multi-user access, use DodoDentist's professional dental practice management software.
Primary dentition (deciduous, baby, or milk teeth) consists of 20 teeth that erupt between ages 6 months and 3 years. They are gradually replaced by the 32 permanent teeth from age 6 onward. This tool supports both dentitions; toggle the Dentition switch to switch between them.
