First we will see what the meaning of antiderivation is? An antiderivative of a
function f can be thought as a function F whose derivative is equal to f or we
can say that F' = f.

ANATOMY of TEETH 2
1. Anatomy of a tooth. a. Anatomical crown- portion of tooth covered with enamel Dental Anatomy Anatomic crown
b. Clinical crown - visible part of tooth above the gum line . Anatomical crown Clinical crown Dental Anatomy
c. Root (1) Part of tooth embedded in the alveolar process and covered by cementum. Dental Anatomy
d. Apex- tapered end of root tip.
e. Apical foramen-
the root tip.
3. Tissues of the tooth. a. Enamel (1) Makes up anatomic crown. (2) Hardest material in the human body. (3) Incapable of remodeling and repair. Dental Anatomy
(1) Makes up bulk of tooth.
(2) Covered by enamel on crown and cementum on the root.
(3) Not as hard as enamel.
(4) Exposed dentin is often sensitive to cold, hot, air, and touch (via dentinal tubules).
Dentin Enamel Dentinal Tubules
(1) Covers root of tooth.
(2) Overlies the dentin and joins the enamel at the cemento-enamel junction (CEJ).
(3) Primary function is to anchor the tooth to the bony socket with attachment fibers.
CEJ Dentin Enamel Dentinal Tubules Cementum
d. Pulp (1) Made up of blood vessels and nerves entering through the apical foramen. (2) Contains connective tissue, which aids interchange between pulp and dentin. Dental Anatomy
Dentin Enamel Dentinal Tubules Cementum Pulp
a. Alveolar process.
(1) Bone extensions of the maxillae and mandible that supports the teeth .
(2) Cortical plate is the dense outer layer of bone covering the spongy (cancellous) bone
Dentin Enamel Dentinal Tubules Cementum Pulp Alveolar Process Cortical Plate Spongy Bone
b. Periodontal ligaments. (1) Dense connective fibrous tissues that connect teeth to the alveolar bone. (2) One end is embedded in cementum and other end in bone. (3) Supports and protects the tooth from normal shock. Dental Anatomy

c. Gingiva - surrounds the teeth and covers the alveolar process. Dental Anatomy
