Try DodoDentist freeAn odontogram is a standardised diagram of all teeth in the mouth, used by dentists and hygienists to record and track the clinical condition of each tooth. 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.
Deux systèmes de numérotation dominent la pratique clinique. La notation FDI (ISO 3950) est utilisée en Europe, en Amérique du Sud, en Asie et dans la plupart du monde. Chaque dent reçoit un code à deux chiffres : le premier chiffre (1–4 pour les dents permanentes, 5–8 pour les dents de lait) identifie le quadrant, et le deuxième (1–8) identifie la dent dans ce quadrant. Ainsi, la première molaire supérieure droite est 16, et la canine inférieure gauche est 33.
Universal numbering (used in the USA) assigns each permanent tooth a unique number from 1 to 32, starting at the upper right third molar (#1) and going clockwise to the lower right third molar (#32). Primary teeth are lettered A–T. While Universal is simple to memorise for a single-arch view, FDI is more intuitive for cross-referencing quadrants and is preferred in international publications. This online odontogram supports both — toggle freely and the Findings Summary updates accordingly.
Un dossier dentaire complet enregistre bien plus que les caries. Les restaurations (obturations), couronnes, bridges fixes, traitements endodontiques, scellants, implants et dents manquantes ou extraites apparaissent tous sous forme de symboles ou de codes couleur. Les observations parodontales — profondeurs de sondage, récession, saignement au sondage, implication de furcation — sont souvent notées sur une grille parodontale séparée. Les systèmes numériques comme DodoDentist superposent les deux sur le même diagramme dentaire pour obtenir une image clinique complète.
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.
Les odontogrammes sur papier sont encore courants dans les petits cabinets et cliniques universitaires, mais la saisie numérique présente des avantages évidents. Les dossiers numériques sont lisibles, consultables et partageables ; ils peuvent être associés aux radiographies et aux plans de traitement ; et ils éliminent les erreurs de transcription. Les logiciels basés sur le cloud comme DodoDentist ajoutent des rappels de rendez-vous, l'intégration de la facturation et l'accès multi-appareils — afin que vos dossiers soient disponibles sur votre tablette au fauteuil, sur votre ordinateur de bureau à la réception et sur votre téléphone entre les cliniques. L'outil interactif de cette page vous permet de découvrir comment fonctionne la saisie numérique avant de vous engager dans un système complet.
Le tableau ci-dessous répertorie les abréviations les plus courantes utilisées en odontologie et leurs significations en langage clair. Les conventions peuvent varier légèrement selon les cabinets et les pays.
| Abbreviation | Signification |
|---|---|
| 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.
