Overview of the Dentition Flashcards
Is your first set of teeth
Primary dentition
Primary Dentition is also known as
Deciduous Dentition
Are the 20 Permanent teeth that replace the 20 primary teeth after they are shed
Succedaneous teeth
This period is the time when children have both primary and permanent teeth
Mix dentition
Begins when the last primary tooth is last
Permanent Dentition
This usually happens at about 12 years of age
Permanent dentition
The two arches of the mouth
Maxillary
Mandibular
The maxillary and mandibular arches are each divided into halves; the resulting four sections are called
Quadrants
The Four types of teeth found in the adult dentition are
Incisors
Canines or Cuspids
Premolars or Bicuspids
Molar
Are the incisors and canines
Centrals
Laterals
Cupsids
The canines are used for
Cutting
Tearing
The molar and premolars are used for
Chewing
Grinding food
The five surfaces of the teeth are
Mesial Distal Facial Lingual Masticatory
The crown of the tooth narrows toward the cervical line on all the teeth in the dentition.
Contours the teeth
narrows toward the cervical line on all the teeth in the dentition.
The crown of the tooth
Defined as the relationship between the maxillary and mandibular teeth when the upper and lower jaws are in fully closed position
Occlusion
occurs when the jaws are closed in a position that produces maximal stable contact between the occluding surfaces of the maxillary and the mandibular teeth
Centric occlusion
This system uses the permanent maxillary first molar as key to occlusion and malocclusion
Angle’s classification system
It is the tooth-numbering system used most often in the United States
Universal number system
The permanent teeth are numbered from 1 to 32 starting at
the upper right third molar
The permanent teeth are numbered from _______ starting at the upper right third molar
1 to 32
Uses a two-digit tooth-recording system based on the quadrants
ISO/FDI numbering system
Used brackets to represent each quadrant and number for each tooth in the quadrant; for permanent dentition the central incisor in identified as tooth number 1 in each quadrant
Palmer notation system
Anterior teeth include
Incisors and canines
The ________ of the tooth narrows toward the cervical line on all of the teeth in the dentition
Crown
key to occlusion and malocclusion in the angles classification system
Maxillary first molar
Palmers Notation system used brackets to represent each quadrant and numbers for each tooth in the quadrant; for permanent dentition, the central incisor is identified as tooth letters 1 in each quadrant
False
