What are the three major functions of the Teeth and there definition ?
Phonetics - speaking
aesthetics - appearance
What is the function of the anterior teeth ?
What is the function of the posterior teeth ?
Anterior Teeth = incising
Posterior Teeth = grinding
Explain the concept of teeth form to function ?
Teeth are formed to take the shape of the job they will be performing.
Carnivores - tearing meat
Herbivores - grinding vegetation
Omnivores - Both Lateral and vertical chewing
Name the two arches and the quadrants represented by them ?
Maxillary Arch - Right and Left Quadrant
Mandibular Arch - Right and Left Quadrant
Name the Anterior Teeth and the Posterior Teeth ?
What is an alternate name for Canines?
What is an alternate name for Premolars?
Anterior Teeth - Incisors and Canines (Cuspids)
Posterior Teeth - Premolars (Bicuspids - sometimes three cusps Tricuspids) and Molars
Explain these tooth numbering systems ?
Universal (1-32 and A-T)
Federation Dentare Internationale
Palmer notation (quadrant/tooth)
Universal numbers all teeth Right to Left and in a clockwise fashion.
Universal for deciduous teeth - A-T
Federation Dentare = Quadrant and tooth number. Example - canines (13,23 ,33, 43)
Palmer Notation= It is a cross quadrant with the number 1-8
What is the Anatomical crown made of ?
What is the Anatomical root made of ?
What is the clinical crown ?
What is the clinical root ?
Anatomical crown: enamel
Anatomical root : cementum
The clinical portion is the portion you can see with the naked eye.
What is enamel ?
What is cementum ?
What is Dentin ?
Enamel - the hardest substance in the human body , but it is brittle .
Cementum - is the the surface layer of the tooth root
Dentin-Main component of the tooth
Draw the Dentoenameljunction (DEJ) ?
Draw the Cementoenameljunction (CEJ) aka cervical line ?
where the Dentin and enamel meet.
where the cementum and enamel meet.
Draw the pulp cavity -include the horns , canal , and chamber ?
What does the pulp consist of ?
Blood vessels and nerves.
Identify the following direction/surfaces
Facial - “outside” surface (aka buccal and labial)•Lingual - “inside” surface (aka palatal)•Mesial - toward midline•Distal - away from midline•Incisal and occlusal - top surfaceGingival (towards thegums; cervical)
What is Proximal vs Interproximal vs intraproximal ?
Interproximal: between two adjacent teeth
Proximal : distal or mesial
intraproximal : inside
Draw the thirds on a maxillary Incisal tooth , facial and proximal view ?
Top to Bottom
Right to Left
What are the three functions of proximal contact areas ?
–Aids in food
Is the distal contact more cervical than the mesial contact ? T or F
What is the Height of Contour ?
Height of contour (HOC) = greatest
point of curvature of a crown
Which way does the Cervical line (CEJ) curve facing the lingual and facial aspects ? Which way does the cervical curve on the mesial and distal aspects?
Draw it ?
Mesial and Distal = incisally /occlusally
Facial and Lingual = apically
Where is the root usually the widest ?
How many roots do the Anterior teeth and Premolars possess ?
How many roots do the Posterior Teeth possess? if more than one where are they located.(ex. mesial , buccal ...)
