3 Major Salivary Glands

Parotid/Stenson


Submandibular/Wharton's


Sublingual/Duct of Rivinus



1st Sexton

Central Incisor


Lateral Incisor


Canine

2nd Sexton

Pre-Molars

3rd Sexton

Molars

Line Angle

Two surfaces of a tooth that meet

Point Angle

Where 3 surfaces of a tooth meet


Where two line angles meet

Cervical

Surface on gum line

Tooth Surface Naming Convention

1. Proximal Surfaces


2. Facial Surfaces


3. Occlusal Surfaces

Palmer's Notation

Break teeth into 4 quadrants


Go from mesial to distal teeth


No double digits


Graphic Image denotes which quadrant it is

International Notation

Break into 4 quadrants (Right Maxillary, Left Maxillary, Left Mandibular, Right Mandibular)


Use Quadrant number as the first number of the tooth's identification


Second number is mesial to distal


Always double digits



Incisors Function During Mastication

Used to bite food

Canine

Used for ripping and tearing food apart


Holding food


Sharpest teeth

Premolar/Bicuspid Function

Chewing and grinding food

Molars Function

Chewing and grinding food

Anterior Teeth Shape

Triangular

Maxillary Posterior Teeth Shape

Trapezoidal

Mandibular Posterior Teeth Shape

Rhomboidal

Characteristics that contribute to self cleansing

Proximal Contacts


Interproximal Spaces


Embrasures


Facial and lingual contours


Curvature of the Cementoenamel Junction

Teeth Features That Indirectly Contribute to Stability During Function

Cusp Form


Proportions of crowns and roots


Root form


Anchorage and angles at which teeth are set in the jaws

Interproximal Spaces

Triangular in shape


Papillary gingiva/Interdental papilla forms the sides and base


When there is loss of gingiva, there is increase in size

Proximal Contact Areas

Consist of mesial and distal contact areas


Proper contacts prevents food impaction


Prevent trauma to the papillary gingiva


Provide support for the teeth


Improper contacts can contribute to periodontal disease

Embrasures/Spillways

Facial, lingual, incisal or occlusal to contact area


Prevent food impaction


Dissipate occlusal forces


Allows self cleansing


Gigival stimulation

Anterior Teeth Labial and Lingual Embrasure Size Comparison

Labial and Lingual embrasure are the same size


Posterior Teeth Buccal and Lingual Embrasure Size Comparison

Buccal embrasure is narrower than the Lingual embrasure

Incisal and Occlusal Embrasures Size

Size increases from anterior to posterior

Cervical (gingival) Embrasures Size

Size decreases from anterior to posterior

Function of Facial and Lingual Contours

Determines position of tongue and lips


Directing food at appropriate angle


Gingival stimulation


Prevent food impaction

Height of Contour

Allow for adequate gingival health


help form the mesial and distal contact area


Should be occlusal to Cementoenamel Junction

Lingual Height of Contour for Anterior Teeth

Cervical 1/3

Lingual Height of Contour for Posterior Teeth

Middle 1/3

First Molar Lobes

5 Lobes

Second Molar Lobes

4 Lobes

Third Molar Lobes
