Study Notes

Overview of Dental Anatomy and Charting

Understanding tooth morphology involves identifying the size, shape, and structure of individual teeth.
Permanent and primary teeth can be categorized by location, anatomical features, and functions.
Eruption timelines for primary teeth (around 6 months to 3 years) and permanent teeth (6 years to late teens) are critical for dental assessment.
Dental arches and quadrants are essential for organizing and describing the mouth's structure.

Primary/Deciduous Dentition

Primary teeth are smaller, whiter, and less mineralized compared to permanent teeth.
Functions include mastication, lip support, speech formulation, and maintaining space for secondary teeth.

Secondary/Permanent Dentition

Consists of larger and more durable teeth that replace primary teeth.
Ensures a full set of teeth for adult functions, including improved chewing efficiency.

Tooth Morphology and Tissues

Teeth are composed of different tissues, each serving unique functions within the oral cavity.
The root of the tooth anchors it to the jaw and contains vital tissues like pulp and nerves.

Tooth Surface Definitions

Mesial: Surface closest to the midline of the dental arch.
Distal: Surface farthest from the midline.
Buccal: Surface in contact with the cheeks.
Labial: Surface in contact with the lips.
Lingual: Surface in contact with the tongue.
Palatal: Surface in contact with the hard palate.
Occlusal: Biting surface of posterior teeth.
Incisal: Cutting surface of anterior teeth.
Proximal: Surface in contact with adjacent teeth.

Importance of Dental Charting

A visual representation assists in diagnosis and treatment planning.
Facilitates patient counseling regarding dental needs.
Serves essential functions for legal protection and forensic identification in emergencies.

Charting/Numbering Systems

FDI System: International coding system used widely, especially in Canada and Europe.
Universal/National System: Used in the U.S.; teeth are numbered 1-32 for permanent teeth and A-T for primary teeth.
Palmer System: Uses quadrants with numbers and letters for permanent and primary teeth, respectively.

Basic Charting Terms

Abscess: A pus collection due to infection.
Crown: A cap covering a tooth, made of gold, porcelain, or stainless steel.
Bridge: A prosthetic device replacing missing teeth, consisting of abutments and a pontic.
Denture:
- Complete dentures are for missing all teeth in an arch.
- Partial dentures are for some missing teeth.
Diastema: Space between teeth, commonly seen between maxillary central incisors.
Drifting: The movement of teeth due to the support they provide to each other within the dentition.
