Intro to Dental Anatomy

What is Enamel?

Its the hardest substance in the human body, it covers visible portion of the tooth

What is Dentin?

It makes up the bulk of the tooth, covers largest area of the tooth and is the second hardest tissue in the human body

What is Cementum?

It covers the root of the tooth from the crown all the to the tip of the root

Where is the Pulp of a tooth found?

Found in the hollow center of the tooth

Name the 4 things contained within the Pulp of the tooth

Blood vessels, nerves, lymphatics and variety of primitive connective tissues

What is the Pulp Cavity?

Its a chamber inside the tooth that is surrounded completely by dentin

Difference between Pulp Chamber vs Root Canal

Pulp chamber is in the crown, it wider and in the center

Root canal is a narrower canal that goes down the root of the tooth

Describe the Crown of a tooth

Its the half top of the tooth covered by enamel

Describe the Root of a tooth

Its the half bottom of the tooth covered by cementum

Describe the Root Apex of a tooth

The tip of the root

Describe the Apical Foramen of a tooth

A hole at the root of the tooth where our pulp exist

Describe the Cementoenamel (CEJ) of a tooth

Its where enamel and cementum join

Describe the Dentinoenamel (DEJ) of a tooth

Its where dentin and enamel join

Describe the Cementodentinal (CDJ) of a tooth

Its where cementum and dentin join

What is Periodontium

The 4 supporting structures of teeth

Define Gingiva

The soft tissue in the mouth (gums)

Define Alveolar Bone

The bone that make up the surrounding area of the tooth (jawbone)

Define Periodontal Membrane

A soft tissue/ligament that connects the tooth and the alveolar bone

Define Cementum

It connects the periodontal membrane to the hard structures on the tooth, and the periodontal membrane is connected to the hard bone

What is the Anatomic Crown?

It is the part of the crown covered by enamel

What is the Clinal Crown?

Is it the part of the crown which is above the gingiva

Define Maxillary Teeth

Teeth that are in the upper jaw

Define Mandibular Teeth

Teeth that are in the bottom jaw

List the 8 tooth types

Central Incisor, Lateral Incisor, Canine/Cuspid, 1st premolar/bicuspid, 2nd premolar/bicuspid, 1st molar, 2nd molar, 3rd molar

Define Quadrant

Maxillary Right, Maxillary Left, Mandibular Right, Mandibular Left

What teeth are Anterior?

The six front teeth

What teeth are Posterior?

The premolar and molar teeth

What is DAQT?

Dentition, Arch, Quadrant, Tooth type, its used for naming each tooth

Define the Mesial Surface

The surface closest to the midline

Define the Distal Surface

The surface away the midline

Define the Facial Surface

The face side of the teeth

Define the Labial Surface

The anterior teeth (lip)

Define the Buccal Surface

The posterior teeth (check)

Define the Lingual Surface

The tongue surface side

Define the Occlusal Surface

The biting surface on posterior teeth

Define the Incisal Surface

The biting surface on anterior teeth

Define the Line Angles

An angle formed by two surfaces Ex: mesiolingual

Define the Point Angles

Angle formed by three surfaces Ex: mesiolabiolincisal

What is another name for the cervical line?

CEJ Cementoenamel junction
