Study Notes

Dental Anatomy

The enamel is the outer surface of the anatomical crown, it is the hardest substance in the body, composed of 96% inorganic material and 4% organic
The cementum is a layer of connective tissue surrounding the root of the tooth
The dental pulp is the soft fleshy connective tissue inside the tooth, containing nerve fibers, blood vessels and lymph
The gingiva is a tough fibrous layer of connective tissue that covers the bone of both jaws. It is richly supplied with blood vessels
The dentine forms the bulk of the tooth and is slightly yellow in color. It can repair itself by laying down a tertiary layer

Functions of Teeth

The primary function of teeth is to masticate (chew) food
Teeth aid in speech production
The teeth help with swallowing by providing a surface for the tongue to push food against

Tooth Function cont…

The incisors are situated at the front of the mouth and are used for biting and cutting food
The canines are situated behind the incisors and are used for tearing food
The premolars are situated behind the canines and are used for crushing and grinding food
The molars are situated at the back of the mouth and are used for crushing and grinding food

Dental Notation

The Palmer notation uses a system of lines and numbers to identify the different teeth, with the upper teeth drawn on the left side and the lower teeth on the right side
The FDI notation uses a two-digit code to represent each tooth, with the first digit representing the quadrant and the second digit representing the tooth
