The teeth Flashcards
What is the general function of the teeth?
to break down food material during mastication in order to increase its surface area to facilitate enzyme activity and absorption
What is the hardest substance in the human body?
Enamel of the teeth
What covers the crown of the tooth?
Enamel
What is directly internal to the enamel?
Dentin
What makes up most of the tooth?
Dentin
What fills the central cavity of the tooth?
Pulp
What is contained within the pulp?
blood vessels, nerves, lymphatics all enter the pulp through the apical foramen
What is the bone like substance that covers the root of the tooth?
Cementum
What is the part of the tooth that projects above the gingivae and is covered by enamel?
The Crown
What is the junction between the crown and root of the tooth?
Neck
What is the part of the tooth that is embedded within the alveolar process of the maxilla or mandible and is covered by cementum?
Root
What is the common name for the gingivae?
The Gums
What is the gingivae?
Specialized oral mucosa that surrounds the teeth and covers adjacent alveolar bone
What is the type of tooth that is chisel-shaped and designed for cutting?
Incisors
These single rooted, pointed teeth are made for cutting and are used for puncturing and tearing. What teeth are these?
Canines
What teeth are single rooted, with broad chewing surfaces and are used for grinding?
Pre-Molars
What teeth are multi-rooted with very broad chewing surfaces and are used for grinding?
Molars
What is the surface of the teeth that faces the lip in the inscisors and canines?
Labial Surface
What surface of the teeth that faces the cheeks int eh premolars and molars?
Buccal surface
What is the surface of the teeth that faces the tongue?
Lingual Surface
What is the surface of the teeth that faces anterior and toward the mid-line?
Mesial Surface
What is the surface of the teeth that faces posterior and away from the mid-line?
Distal Surface
What is the surface of the teeth that is used for chewing?
Occlusal Surface
What is the dentition?
The set of the teeth
What is the total number of deciduous teeth? How many are in each quadrant?
20; 5
What is the total number of permanent teeth? How many are in each quadrant?
32; 8
What teeth are missing in the deciduous teeth?
Premolars
What teeth will replace the deciduous molars?
Adult/Permanent Premolars
Which teeth are commonly called the “wisdom teeth”? Why are they called this?
The 3rd Molar in the adult teeth: They do not erupt until 17-20 years of age
What is the innervation of the Maxillary (upper) teeth?
Superior Alveolar Branches of the Maxillary Division of the Trigeminal Nerve (CN V)
What is the innervation of the Mandibular (lower) teeth?
Inferior Alveolar Branches of the Mandibular Division of the Trigeminal Nerve (CN V)
