A tooth is divided into two parts
|
the crown and one or more roots.
|
|
|
The anatomical crown
|
is that portion of the tooth encased in enamel.
|
|
|
also called canines, used for cutting and tearing
|
Cuspids
|
|
|
translucent and can vary in color from yellowish to grayish white.
It can endure crushing pressure of approx. 100,000 psi. |
Enamel
|
|
|
also referred to as premolars, used for cutting and tearing.
|
Bicuspids
|
|
|
Constitutes the largest portion of the tooth
Dentin is harder than bone but softer than enamel. |
Dentin
|
|
|
Types of teeth
Incisors: used to incise food Cuspids: also called canines, used for cutting and tearing Bicuspids: also referred to as premolars, used for cutting and tearing. Molars: used for grinding and chewing solid masses of food. |
Molars
|
|
|
Bonelike tissue that covers the roots of the teeth in a thin layer.
Main function is to anchor the teeth to the bony walls of the tooth sockets in the periodontium |
Cementum

|
|
How many teeth do we have
|
1st set (baby teeth)???

|
|
used to incise food
|
Incisors
|
|
|
commonly caused by a bacterial infection
|
Abscess
|
|
|
An enclosed pouch or sac that contains fluid or semisolid material.
|
Cyst-
|
|
|
-results when the pulp has become inflamed and a small pus-like abscess forms in the pulpal canalo.
|
Periapical abscess
|
|
|
disruption of the superficial covering of the mucosa or skin. May be caused by biting, denture irritation, toothbrush injury, viruses or other irritants.
|
Ulcers
|
|
|
an inflammation involving the gingival tissues.
|
Gingivitis-
|
|
|
the condition in which a tooth is blocked by a physical barrier, usually teeth or bone.
|
Impaction
|
|
|
a chronic inflammatory condition that involves the gingiva, crest of the alveolar bone, and periodontal membrane.
|
Periodontitis-
|
|
|
loss of tooth substances from a chemical process that does not involve bacteria.
|
Erosion
|
|
|
-is the most frequent cause of severe tooth pain.
|
Acute pulpitis
|
|
|
Pulpitis-an inflammation of the dental pulp, usually caused by a bacterial infection resulting from dental caries or fractured teeth.
|
Pulpitis-
|
|
|
-usually a result from an infection of the pulpal tissue causing the pulp to become necrotic (die).
|
Periapical Abscess
|
|
|
If a carious lesion is present gently excavate the cavity.
If drainage occurs through the cavity, the PT may experience a rapid relief of pain. NEVER apply heat to the external surfaces of the face. |
Periapical Abscess
|
|
|
Type IV
|
Root Fracture
|
|
|
- a condition commonly referred to as a dry socket. Normally a results when a blood clot fails to form or washes out of the socket of a recently extracted tooth. Very Painful.
|
Postextraction alveolar osteitis
|
|
|
Type I-
|
Enamel Fracture
|
|
|
Type II
|
Enamel/Dentin Fracture
|
|
|
Type III-
|
Enamel/Dentin Fracture with pulp exposure
|
