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.
Dos sistemas de numeración dominan la práctica clínica. La notación FDI (ISO 3950) se utiliza en Europa, América del Sur, Asia y la mayoría del mundo. Cada diente recibe un código de dos dígitos: el primer dígito (1–4 para permanentes, 5–8 para primarios) identifica el cuadrante, y el segundo (1–8) identifica el diente dentro de ese cuadrante. Así, el primer molar superior derecho es 16, y el canino inferior izquierdo es 33.
La numeración universal (utilizada en EE.UU.) asigna a cada diente permanente un número único del 1 al 32, comenzando en el tercer molar superior derecho (#1) y continuando en el sentido de las agujas del reloj hasta el tercer molar inferior derecho (#32). Los dientes primarios se designan con letras de la A a la T. Aunque Universal es simple de memorizar para una vista de un solo arco, FDI es más intuitivo para hacer referencias cruzadas entre cuadrantes y es preferido en publicaciones internacionales. Este odontograma en línea admite ambos sistemas: cambia libremente y el Resumen de Hallazgos se actualiza en consecuencia.
Un gráfico dental completo registra más que solo caries. Las restauraciones (empastes), coronas, puentes fijos, tratamientos de conducto, sellantes, implantes y dientes faltantes o extraídos aparecen como símbolos o códigos de color. Los hallazgos periodontales —profundidades de sondaje, recesión, sangrado al sondaje, afectación de la furcación— a menudo se grafican en una cuadrícula periodontal separada. Los sistemas digitales como DodoDentist superponen ambos en el mismo diagrama dental para obtener una imagen clínica completa.
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.
Los odontogramas en papel siguen siendo comunes en consultorios pequeños y clínicas de estudiantes, pero el registro digital tiene claras ventajas. Los registros digitales son legibles, buscables y compartibles; pueden vincularse a radiografías y planes de tratamiento; y eliminan errores de transcripción. El software basado en la nube como DodoDentist añade recordatorios de citas, integración de facturación y acceso multidispositivo, para que tus historiales estén disponibles en tu tableta junto al sillón, en tu escritorio en recepción y en tu teléfono entre clínicas. La herramienta interactiva en esta página te da una idea de cómo funciona el registro digital antes de comprometerte con un sistema completo.
La tabla a continuación enumera las abreviaciones de odontograma dental más comunes y sus significados en lenguaje simple. Las convenciones pueden variar ligeramente entre clínicas y países.
| Abreviatura | 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.
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.
Select an active condition from the colour-coded palette (e.g. Caries — red). Then click any tooth on the chart to apply that condition. The tooth changes colour and 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.
