Module: Dental Records, Nomenclature, and

Charting the Oral Cavity


Module: Dental Records, Nomenclature, and Charting the Oral Cavity

Dental Records, Nomenclature, and Charting

the Oral CavityPart A: Dental Nomenclature

Part B: Dental Charts and Abbreviations



Learning Objectives1. Define the Key Terms.

2. Identify the maxillary and mandibular arches.

3. List the hard and soft tissues of the teeth.

4. Name all the teeth.

5. State the tooth surfaces.

6. List common abbreviations used to identify simple, compound, and complex cavities.



Learning Objectives7. Describe systems used for charting permanent

and primary dentition.

8. Explain color indicators and identify charting

symbols.

9. Recognize the quadrants, posterior, and anterior

sextants of the oral cavity.

10. Apply dental charting terminology on a diagram.

11. Distinguish all six cavity classifications.

Tooth Surfaces

Mesial Surface: Surface of toothtowards the midline

Distal Surface: Surface of toothaway from the midline

Occlusal Surface: Chewingsurface of posterior teeth


Tooth Surfaces

Incisal Edge: Cutting edge of anterior teeth

Facial Surface: Surface towards the face

Labial Surface: Surface towards the lipsof anterior teeth

Buccal Surface: Surface towards cheek ofposterior teeth

Lingual Surface: Surface towards the tongue


Dental Numbering Systems

The Universal Numbering System

The Federation Dentaire InternationaleSystem for Numbering

Palmer System for Numbering


Cavity Classifications

Class I Class II

Class IVClass III

Class V Class VI


Basic Charting Terms

• Denture

• Drifting• Restoration• Root Canal

Treatment• Sealant• Abcess

• Bridge• Abutment• Pontic• Caries• Crown


Charting Color Indications and Symbols

• Red represents work to be done.• Blue represents treatment completed.• Amalgam restoration: outlined and filled in solidly

with blue.• Composite restoration: outlined in blue.• Gold restoration: outlined and diagonal lines.• Porcelain restoration: outlined.• Sealant: S on occlusal surface.• Stainless steel crown: outlined with swervy lines.


Assessment Questions

• On which tooth surfaces would pits and fissures be found?

• What is the difference between a Class III and a Class IV cavity?

In the mesial and distal occlusal areas and on the buccal and lingual surfaces

A Class III cavity is a one-surface cavitybetween the anterior teeth, and a Class IVcavity is a two-surface cavity between the teethand includes the incisal angle of the tooth.
