Chapter 4 Dentition Flashcards
(Dentition): Types of teeth, Permanent dental arch
Central Incisor,
Lateral Incisor,
Cuspids (canine),
First bicuspids (premolar),
Second bicuspid (premolar),
First molar,
Second molar,
Third molar (wisdom teeth)
(Dentition)
(Components of a tooth): Crown
area above the gum line
(Dentition)
(Components of a tooth): Root
below the gum line
(Dentition)
(Components of a tooth): Enamel
dense surface for protection
(Dentition)
(Components of a tooth): Dentin
solid portion of tooth
(Dentition)
(Components of a tooth): Pulp
contains nerves and blood vessels within the tooth
(Dentition)
Dental development): Deciduous teeth (shedding teeth
10 teeth in each arch
(Dentition)
Dental development): Permanent teeth (successional teeth
16 teeth in each arch
(Dentition): Dental occlusion
relationship of upper dental arch to lower dental arch when teeth come together
(Dentition)
(Dental occlusion): Class I occlusion
Normal,
Neutrocclusion,
First mandibular molar is one-half tooth anterior to the first maxillary molar
(Dentition)
(Dental occlusion): Class II occlusion
Malocclusion,
First mandibular molar is posterior to normal position,
Mandible is retracted
(Dentition)
(Dental occlusion): Class III occlusion
Malocclusion,
First mandibular molar is anterior to normal position,
Mandible is protruded
(Dentition): Micrognathia
condition in which the mandible is small in relation to the maxilla
(Dentition): Micrognathia, affects
May be part of other genetic syndromes,
May interfere with infant feeding,
May cause abnormal alignment of the teeth
(Dentition): Open bite
anterior teeth do not occlude (do not touch when you bite down) because of excessive eruption of posterior teeth
